INTRODUCTION

One of the functions of Civil Aviation Authority of Nepal is to issue 'licence' through

Licensing and Examination Division of Flight Safety Standards Department to Flight Crew and

Air Traffic Controllers. Besides knowledge and skill, the applicant must possess proper health

condition - physical and mental, and functioning special senses to perform the task. Hence

'Medical Examination and Assessment' of the applicant forms an integral component and a

regulatory requirement, before the licence is issued, whether it be an initial or a renewal. He

also should be free of condition or disease that may cause incapacitation jeopardizing the

safety of flight while performing his duties.

Medical Requirements have been prepared in complete completed cooperation with senior

COSCAP aviation medicine experts as per the guideline of ICAO Annex-1 and Doc 8984. At

the same time necessary conformity with ailment prevalence in Nepal has been taken into

consideration and accordingly implemented. It has been essentially prepared for the Designated

Medical Examiners, Licensing and Examination Division, Civil Aviation Authority of Nepal to

provide guidelines for medical information/standards, Policies and Procedure in order to

provide license requirements of Flight Crew and Air Traffic Controllers and assess their fitness

in presence/absence of medical condition.

Medical Requirements consist of 3 parts:

Part 1 : Requirements for Medical Examination and Assessment

Part 2 : Medical Standards of Licensing Requirements

Part 3 : Guidelines on Medical Conditions.

They are in conformity with ICAO Standards and Recommended Practices, Annex 1 to the

Convention on International Civil Aviation and are duly adopted by Civil Aviation Authority

of Nepal. This Requirement also incorporates Flight Operation Requirements/Personnel

Licensing Requirements issued by Civil Aviation Authority of Nepal and subsequent

amendment. In the preparation of these Requirements, Manual of Civil Aviation Medicine

ICAO, Doc 8984-AN/895, and other Aviation Authorities Regulations and Standards practiced

by leading aviation countries have also been taken into consideration.

As knowledge and techniques are advancing rapidly and more and more experience is

achieved, both in medicine and aviation, these medical requirements may be amended by

Director General, Civil Aviation Authority of Nepal as and when appropriate.

privilege of his license until he has fully recovered.

Such cases should be notified by the applicant at the time of medical examination and in case

of licence holder by himself or airline in writing to CAMA or LED. All relevant medical

papers or document must be submitted.

___________________________________________________________________________

Medical Requirements, Fourth Edition, October 2016 5

CIVIL AVIATION AUTHORITY OF NEPAL

Decrease in medical fitness can usually be assumed to be present in the following situations:

1. After severe illness, injuries, accident, operation, invasive procedures or

hospitalization,

2. Incapacitation for more than 21 days,

3. Problematic use of substances or illicit drugs,

4. Being pregnant

He/she may be required to undergo medical examination and assessment and be certified

medically fit before he exercises the privilege of his license.

1.9 BORDERLINE MEDICAL FINDING

In case of finding which is outside the prescribed normal range or undesirable or indicative of

early sign of disease process, but not necessarily likely to cause incapacitation or jeopardize

the flight safety, the CAMA will inform the applicant or licence holder and may ask further

tests +/or opinion from experts or advise him to see his airline doctor or his doctor to take

timely precautions.

1.10 ACCREDITED MEDICAL OPINION

If the applicant for or the holder of a license does not meet the requirement or is found to have

any condition due to illness, injury or operation or sequelaeae there from which causes or may

cause incapacitation interfering with the performance of duties, further evaluation from the

specialist and additional tests may be required. Such cases may be referred to specialists or

experts for their opinion by CAMA. Opinion received from such special medical evaluation is

called 'Accredited Medical Opinion'. If accredited medical opinion certifies him medically fit,

it indicates that applicant's or holder's failure to meet any requirement, is such that exercise of

the privileges of the licence is not likely to jeopardize the flight safety. And also his relevant

ability, skill and experience of the applicant and operational conditions are given due

consideration in such evaluation. It may be endorsed by CAMA with limitation or restrictions

if necessary, for the sake of flight safety.

1.11 MEDICAL FLIGHT TEST

In some case or where there is suspicion of overt manifestation of decreased physical ability or

functional limitation, he may be tested in actual flight to see if he can operate the aircraft

without compromising the flight safety during routine and emergencies. This will be done

under the supervision of an instructor pilot, and preferably with CAMA and can also be

combined with pilot proficiency check.

___________________________________________________________________________

Medical Requirements, Fourth Edition, October 2016 6

CIVIL AVIATION AUTHORITY OF NEPAL

1.12 FLEXIBILITY CLAUSE

If the applicant has deficit or defect, numerical or otherwise, that may cause a degree of

functional incapacity, CAMA can recommend for renewal of license, with the evidence that

the applicant has already acquired and demonstrated ability, skill and experience which could

compensate for the failure to meet the prescribed medical standard. Besides it is believed not to

produce any hazard either of incapacity or of inability to perform his duty safely. However this

provision may be applied with endorsements e.g. operational limitation or restriction,

assistance like glasses, additional tests in medical examination, frequent medical examination,

etc. It will be done usually on 'accredited medical opinion'. This is popularly called as 'waiver'

and assessed as 'fit' under 'flexibility clause' only after careful consideration of all aspects of

the individual case.

1.13 MEDICALLY UNFIT OR DEFERRED MEDICAL ASSESSMENT

If the applicant for the licence, whether it be initial or renewal, does not clearly meet the

medical requirements or is found to have any condition due to illness, injury or operation or

sequelaeae there from or influence of psycho-active substances or problematic use of

substances or drugs, which causes or may cause incapacitation interfering with the

performance of duties safely, he will not pass the medical assessment. He will be certified

medically unfit. However, in case of doubt, medical assessment is deferred until further

evaluation is done and then after only final certification is made whether medically fit or unfit.

1.14 SUSPENSION OF LICENCE ON MEDICAL REASON

In case of licence holder on receiving notice in writing or through reliable source that he does

not meet the medical requirement or is found to have any condition due to illness, injury or

operation or sequelaeae there from or influence of psycho-active substances or problematic use

of substances or drugs, which causes or may cause incapacitation interfering with the safe

performance of duties, his licence may be suspended, until full medical examination and

assessment is done later at pre-specified time or after he fully recovers. At that time he must

submit complete medical report with diagnosis, treatment and progress from the treating

doctor. If it is going to take long time, they must submit the medical report periodically,

usually not later than six months, so as to maintain their record and continuity. This period of

observation is usually two years at the maximum, after which the will be treated as for initial

issue of licence.

1.15 PROVISION OF APPEAL

If the licence is denied or suspended or deferred on medical ground and the applicant for or

holder of license is not satisfied, he has the right of appeal to Director General, CAAN within

the period of 45 days. The DG in turn may get second opinion.

Medical Requirements, Fourth Edition, October 2016 7

CIVIL AVIATION AUTHORITY OF NEPAL

1.16 EXPIRED LICENCE DUE TO MEDICAL REASON

The flight crew or air traffic controller whose licence has expired due to medical reason will

have to undergo medical examination and assessment and be assessed medically fit for the

reissue of the licence. During the medical examination he should submit full medical report of

the treating physician with all the investigations and treatment and report that he has fully

recovered from the medical condition. If he has missed two consecutive medical examinations

from the validity period of license, his medical examination will be as in the initial issue of

licence and other tests may be required.

ascertain his medical fitness and to comply with medical requirements of CAAN, the licence

holder shall not refuse to undergo such examination

1.18 DISPENSATION OF MEDICAL EXAMINATION AND

ASSESSMENT

If the license holder is in such a region where medical examination is not possible, LED can

extend the validity period to a period of 3 months in case of CPL, ATPL and Flight Engineer

and other flight crew for commercial purpose and 6 months in case of PPL. This will be

considered in exceptional circumstances for one time only. But in such case he should forward

to LED a medical certificate from a local registered practitioner declaring his medical fitness in

accordance with the Medical Requirements, if possible.

1.19 EXCEEDING CUMULATIVE FLIGHT HOURS LIMITATION

The privilege of the licence will automatically cease the moment the crew crosses the

cumulative flight hours limitation as laid down in FOR. However on special circumstances it

maybe waived only if the there is a written application and LED is convinced and medical

examination by CAMA is satisfied and certifies him medically fit. He will specifically insures

that there is no symptoms and signs of fatigue. This will be in exceptional situation and for the

shortest possible period only.

PART 3 GUIDELINES ON MEDICAL CONDITIONS

Before issuing a license, initial or renewal, the applicant of flight crew or air traffic controller licence is

medically examined. If he passes the medical assessment of the required Class as per the standards laid

down in Medical Requirements, he will be assessed as Medically Fit and recommended for the issue of

the licence. If the applicant is found to have any finding or medical condition that does not clearly meet

the medical requirements, he fails the medical assessment and so will not be recommended for issue of

licence. This also applies to the licence holder.

Hence the main objectives of the medical examination and assessment are to insure that the applicant or

holder is:

1. physically and mentally capable of performing his flying duties in a safe manner. This includes

having full use of his faculties i.e. visual ability, hearing, colour perception, balance, muscle

sense, etc. and his ability to evaluate the flight conditions and to decide the safe course and act ;

2. free of disease or condition which may suddenly render him incapable of performing his duties in

a safe manner during on-going flight (acute incapacitation) or imperceptibly lead to commit or

omit actions that may jeopardize safety of the on-going flight (subtle incapacitation); and

3. free of disease which may slowly but within the period of validity of his licence reduce his

capacity for performing his duties below the acceptable level.

In borderline or doubtful findings or persistence of residual pathology or reduced function or disability

after recovery from illness or operation or accident or any other medical event, he may be considered for

recertification. Such cases are usually referred to the specialists who may require additional tests. All

medical reports from treating physician should be provided, when applicable. If such specialists are of the

opinion that the findings or residual pathology or reduced function or disability is not likely to interfere

with the safe operation of the aircraft or with the safe performance of his duties, he may be assessed as

medically fit. In such evaluation his relevant ability, skill and experience and operational conditions are

also given due consideration. On such accredited medical opinion he may be recommended for issue or

renewal of the licence by Aviation Medical Consultant or Civil Aviation Medical Board. On that

licensing may be issued or renewed. In such cases operation 'limitation' or 'restriction' is usually endorsed

for the sake of flight safety. They are, in case of flight crew, are as given below:

'Fit to fly as co-pilot only'

'Fit to fly with suitably qualified co-pilot'

'Fit to fly with a safety pilot with dual control in single pilot aircraft'

'Fit to fly solo in cargo or non-revenue passengers flights only'

Later he may be allowed to fly solo or without restriction

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

There may be other endorsements as use of appliances e.g. glasses, frequent assessments, additional tests,

specialist reports, accredited medical opinion, practical flight tests, etc. when the safe performance of the

licence holder's duties is dependent on compliance of such endorsements.

In case of Class II and Class III medical assessments, especially for private and recreational flying, less

stringent medical standards may be acceptable from the nature of their work and safety concern, though

the principle of evaluation will be the same.

If he is to be on medications, those should be from the approved list or should get prior approval from

Aviation Medical Consultant or CAMB.

Continuous supervision and follow-up will be important in some cases. It should be the responsibility of

Airline doctor or his family physician or even the medical examiner, if he is providing medical care.

Hence all airlines are expected to have a Medical Unit or at least a Medical Officer in their establishment,

who will be responsible to look after the health and follow up of such flight crew and other personnel of

the airline.

Following descriptions include only common conditions in general population, so also in the aviation

personnel, These guidelines, though, are meant for all applicants and holders of all classes of medical

assessments, are more directed to the flight crew.

These guidelines are given in order to help the Aero-Medical Examiner, Civil Aviation Medical Board to

deal with such medical conditions and to have a scientific, sound and uniform practice in assessing the

applicant for or holder of licence. On those guidelines appropriate actions and decision will be taken and

at the same time trying to retain the applicant or holder without compromising the flight safety. However

guidelines are not necessarily final. These guidelines may be modified from time to time on the basis of

further knowledge and experience.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

3.1 NEURO-PSYCHIATRIC CONDITIONS

The neuro-psychiatric symptoms varies from mild anxiety symptoms due to day-to-day events and

stresses to severe and incapacitating disorders. If there is doubt or suspicion during the medical

examination or on verifiable information from an identifiable source, psychiatric evaluation will be

required detailing his opinion and recommendation.

3.1.1 Anxiety based disorders (Neurosis): An applicant with the history of anxiety based disorder of

significant severity requiring psychotropic medication or admission in hospital or prolonged treatment or

recurrence, are normally rejected for all classes of licence.

The licence is suspended or is not issued during the psychiatric illness and while on treatment. But if the

illness was not of long duration and the psychotropic drugs were stopped for 6 months or more, he may

be considered for issue or recertification on the psychiatrist's accredited medical opinion with restriction

as 'to fly as or with suitably qualified co-pilot in the multi-pilot aircraft' or 'to fly with safety pilot with

dual control in single pilot aircraft' for 6 months after which he shall be evaluated again.

3.1.2 Sociopathic Personality Disorders: All such cases, if proved, are assessed as unfit for all classes

of licence.

3.1.3 Psychotropic Substance/Alcohol Abuse: These reduce performance, slows reaction and impair

judgment. The detrimental effect persists even after these substances have been eliminated from blood.

There are every chance of recurrence even after stopping them.

Hence history of abuse or effect of abuse of these substances are incompatible for flying. After successful

treatment and complete abstinence for six months or more, he may be considered for issue or

recertification on the psychiatrist's accredited medical opinion and provided abstinence is secure and

three monthly follow-up is maintained. It will be with restriction as 'to fly as or with suitably qualified

co-pilot in the multi-pilot aircraft', or 'to fly with safety pilot with dual control in single pilot aircraft.

Failing to comply with this or relapse will make him permanently unfit.

3.2 NEUROLOGICAL CONDITIONS

3.2.1 Seizure: Disturbance of consciousness in the flight personnel is usually due to transient cerebral

hypoxia following syncope, or more rarely due to cardiac disorder or an epileptic seizure. An epileptic

seizure occurring during flight is an unacceptable safety hazard even in the multi-pilot aircraft. It may be

a partial seizure and not immediately apparent to the other pilot or a generalized tonic-clonic seizure

consequences of which may disrupt the equipment or control. This may be especially hazardous if it

occurs during takeoff or landing. Hence it is important to be sure whether it is due to 'faint,' or 'fit i.e.

seizure'.

Epilepsy is by definition a recurrent seizure and causes sudden incapacitation. Hence the diagnosis of

epilepsy leads to permanent failure in all classes of medical assessment.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

Single seizure, if afebrile and unprecipitated, may be assessed as fit for certification after 10 years,

provided there is no recurrence, and he is off drugs for five years or more. He will also require normal

EEG and MRI of brain and a neurologist's opinion that there is no likelihood of having another seizure.

But it will be with restriction as 'to fly as or with suitably qualified co-pilot' in the multi-pilot aircraft or

'with safety pilot with dual control in single pilot aircraft' for one year, after which the restriction may be

lifted.

History of childhood febrile seizure, occurring before the age of 5 and not associated with neurological

deficit, may be considered fit for certification.

Post-traumatic epilepsy is disqualifying.

Abnormal EEG or MRI or recurrence of epilepsy, on the background of previous history of epilepsy

will be permanently disqualifying.

3.2.2 Head Injury: Accidents associated with head injuries are common in the modern world.

Head injurywith loss of consciousness and focal neurological deficit, depressed skull fracture,

cerebral injury or post-traumatic headache will be disqualifying.

There are two major concerns following head injury with loss of consciousness. One is the neuro-

psychological consequences of the head injury in the individual though without focal neurological

deficits, could be in the form of dysfunction in number of functional executive activities of brain. This is

the effect of acceleration/deceleration forces on the skull and the brain causing damage to cortical and

diffuse white matter. The other concern is the possibility of seizure. Both are incompatible to flight. The

duration of loss of consciousness and length of post-traumatic amnesia both show a good correlation of

severity of brain damage and occurrence of epilepsy.

Probability of epilepsy is greater in those with penetrating skull injuries. Even with full physical and

neuro-psychological recovery there is an increased probability of seizures for over 10 years. In general,

those who develop post-traumatic seizures, 50 % will occur within one year and 70 – 80% within two

years. Thereafter the incidence is 3 – 5 % per year upto ten years.

Depending upon the initial level of risk if the epilepsy has not occur two years after head injury the

reduction of risk may allow a pilot to return to flying without restriction, or as or with a copilot. After

five years this restriction can be removed.

Head injury with loss of consciousness and after complete recovery of mental and neurological

function may be assessed as 'fit' with or without restriction, after complete neurological examination and

appropriate laboratory and imaging studies. However a period of stabilization and Accredited Medical

Opinion is required before he is recommended.

3.2.3 Headache: Headache is a common symptom and mostly mild and short lived. But some may be

severe and incapacitating, and also chronic or recurring and so hazardous to flight safety.

Migraine: Some migraine presents as frequent attacks of severe headache associated with aura

particularly the disturbance of sight, and neurological disturbance, prostration from vomiting,

photophobia and occasional loss of consciousness. It shall be assessed as unfit for certification. But some

may be considered for recertification and assessed as fit 'to fly as or with suitably qualified co-pilot in the

multi-pilot aircraft' or 'with safety pilot with dual control in single pilot aircraft' for one year. If the

attacks of headache are of lesser severity and infrequent, and if he is in on treatment and free of headache

for more than 6 months. The restriction may be lifted after one year.

Cluster Headache: Chronic cluster headache without remission is assessed as permanently unfit. But if

occurs for a limited period followed by long period of remission, he may be certified fit with restriction

'to fly as or with suitably qualified co-pilot in the multi-pilot aircraft' or 'with safety pilot with dual

control in single pilot aircraft' with suspension of licence during relapse.

3.2.4 Neuralgic Pain: Neuralgic attacks of sudden severe pain as in trigeminal neuralgia and other

neuralgias are distracting and incapacitating and such history are assessed as unfit. But if becomes free

of pain spontaneously or after operation or with treatment and remains so for more than six months

without treatment, he may be considered for recertification with or without restriction. Neurologist

opinion may be required.

3.2.5 Infection: Infection of nervous system can occur sometime in the aviation personnel.

Viral Encephalitis: Generally applicant who has suffered from viral encephalitis would be assessed as

permanently unfit, as he often has residual neuropsychological deficit.

Viral Meningitis: Applicant who is neurologically normal two months after viral meningitis, will be

assessed as fit in al classes.

Bacterial Meningitis: Applicant who has completely recovered from bacterial meningitis may be

assessed as medically fit after one year, provided he is found to be normal on neurological examination,

electroencephalogram, and CT scanning and if there is no focal neurological deficit.

Bain Abscess: Applicant who has suffered from brain abscess is assessed as permanently unfit due to

increased risk for epilepsy from the scarring that forms round the abscess.

Guillain Barre Syndrome: Applicant who has made a full recovery from Guillainbarre Syndrome may

be assessed as fit. If he has mild residual weakness, he may be assessed with flight test also.

3.3 CARDIO-VASCULAR CONDITIONS

3.3.1 Hypertension: Hypertension is a common condition in the adult population and cause long term

changes, if not controlled, e.g. damage to major organs including heart, brain, kidneys and eyes. Hence

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

they can be cause of incapacitation jeopardizing the safety of flight. Hypertension is a common cause of

premature loss of licence.

Blood pressure measurement: Blood pressure measurement will be done both in seated and recumbent

positions. The systolic blood pressure shall be recorded at the appearance of thekorotkoffsounds (phase

I) and the diastolic blood pressure at their disappearance (phase V). If the blood pressure is raised and

the resting heart rate is rapid, further observation should be made during the medical examination after

some rest.

Hypertension will be suspected if blood pressure is recorded 140/90 mm of Hg or more in sitting position

after adequate rest. It will be confirmed if it is consistently so on weekly blood pressure examinations for

4 weeks. Hypertension is classified as per new National Heart and Lung and Blood Vessels Institute

(NHLBI) Standards (May 2003), as given below:

Condition

Systolic (mm of Hg)

Diastolic (mm of Hg)

Normal

<120

<80

Prehypertension

120 – 139

80 – 89

Stage I Hypertension

140 – 159

90 – 99

Stage II Hypertension

>160

>100

If the readings are above 140/90 mm Hg but below 160/100 mm of Hg i.e. Stage I Hypertension, an

ambulatory blood pressure measurement (ABPM) for 24 hours will be done to eliminate the white coat

and anxiety induced hypertension.

If 4 blood pressure measurements done at weekly intervals are more than 160/100 mm of Hg i.e. Stage II

Hypertension, no ABPM will be required.

24 hours ambulatory blood pressure measurement: It is programmed to record the blood pressure

every 30 minutes during the day time and every 60 minutes during night time. The applicant is instructed

to keep the arms still during measurements and continue his daily activities other times. He is also to

record the activities as well as time of going to bed and time of rising. For analysis more than 14 systolic

and diastolic blood pressure records during the day time and at least 7 records at night are mandatory.

Definition of normal blood pressure and hypertension using ABPM is given below:

Normotension

Hypertension

(Upper limits by rounding

downwards 0-5 mmHg)

(Upper limits by rounding

upwards 0-5 mmHg)

For 24 hours average

130/80 mmHg

>135/85 mmHg

For day time average

135/85 mmHg

>140/90 mmHg

For night time average

120/70 mmHg

>125/75 mmHg

The applicant with hypertension diagnosed for the first time, will require cardiovascular evaluation for

medical assessment including risk factors and target organs, and consist of:

 Detailed history including family, personal & social,

 Blood tests – Hb, ESR, urea, creatinine, electrolytes, fasting lipid profile, uric acid and fasting blood

sugar

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

 Urine analysis

 Chest X-Ray

 Electrocardiogram

 Echocardiogram

 Exercise Electrocardiogram Test

The applicant who is diagnosed 'Stage I Hypertension' will be treated initially with non-pharmacological

means and monthly blood pressure recording for three to six months maintaining the flight status, and

then with approved anti-hypertensive drugs, if necessary.

The applicant diagnosed as 'Stage II Hypertension' will be certified 'unfit temporarily' for flight duty.

Meanwhile it will be attempted to control the blood pressure by non-pharmacological means -/+

antihypertensive drugs or anti-hypertensive drug will be adjusted if he is already on treatment. The

minimum period of unfit should be 2 weeks from the effective dosage of approved drug or drugs, to

watch the adverse effects of these drugs in that dosage. During this period blood pressure will be

recorded weekly. After the control of blood pressure, he will be followed up monthly for three months

and then 3 monthly, provided blood pressure control is satisfactory.

This should be the responsibility of Airline doctor or his family physician or even the medical examiner,

if he is providing medical care. Before certification of medical fitness all the medical reports from

treating physician should be provided to the medical examiner and then to the Member Coordinator.

Non-pharmacological means or modification of life style (weight reduction, minimizing alcohol

consumption and salt intake, regular exercise,) is the first approach. Cessation of smoking and reduction

of saturated fat intake are to be strongly recommended as it reduces the associated cardiovascular risk.

Following classes of drugs have been identified as acceptable in the management of hypertension in

aviation personnel. viz. Non-loop Diuretics (Hydrochlorthiazide 25 mg/day, Chlorthalidone, Amiloride,

Triamterin, Aldosterone) , Hydrophilic Beta-blockers (Atenolol and metoprolol), Long acting Angiotensin

Converting Enzyme (ACE) Inhibitors (Enalapril, Lisinopril), Angiotensin II receptor blockers and Slow

Calcium channel blockers (long acting dihydroppyridines viz. amlodipine).

On periodic examination of those controlled on acceptable drugs for renewal of licence, the treating

physician will provide the medical report and records of at least 3-monthly blood pressure, and he will

have tests as listed above once every two years during medical examination

Stage I Hypertension is certified 'fit' without restriction, except during the initial few weeks of initiation

of treatment with anti-hypertensive drugs and he will be observed for any side effects.

Stage II hypertension is certified 'temporarily unfit' until his blood pressure is controlled and the anti-

hypertensive drugs cause no adverse effects. Then he will be assessed fit without restriction.

Presence of complication of hypertension will make him 'unfit'.

3.3.2 Coronary Artery Disease: Coronary artery disease is common especially in affluent society. The

incidence is in the increase in this part of the world. Sudden incapacitation is a dreaded situation during

the flight and hence it is the commonest cause of the loss of licence. Not only local lesion of the coronary

arteries are important, but risk factors and life style are also equally important and need no addressed.

Proven history or clinical diagnosis of Myocardial Infarction with or without symptom and with or

without treatment shall be assessed as 'unfit' in both initial and renewal, for all classes of licence. He may

be considered for recertification after one year, if there is no significant residual damage of myocardium

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

and no significant stenosis of coronary artery or its branches and according to accredited medical opinion

the cardiac condition is unlikely to interfere with the safe exercise of the privilege of his licence. It will

be endorsed with restriction for one year to fly as or with a copilot and this restriction may be lifter after

one year. Follow-up of annual cardiological review shall be required by a cardiologist, including

Exercise ECG +/or Myocardial perfusion scintigraphy. At 5 years repeat coronary arteriogram may be

required.

All cases of atypical chest pain or suspected or asymptomatic or symptomatic coronary artery disease will

be assessed as 'unfit' and shall undergo detailed cardiovascular evaluation and investigations, and require

'accredited medical opinion'. Case of angina +/or Exercise ECG positive for reversible myocardial

ischaemia will be assessed as unfit for any class of licence. If he was treated with coronary

angioplasty or with coronary artery by-pass graft, he may be assessed as fit after one year of the

procedure after cardiac evaluation and accredited medical opinion that there is no likelihood of becoming

suddenly incapacitated which would interfere with the safe operation of aircraft and the safe performance

of duties. It will be restricted multicrew operation for one year after which it may be lifted. Follow-up of

annual cardiological review shall be required by a cardiologist, including Exercise ECG +/or

Radioisotope Myocardial Perfusion Scan. At 5 years full cardiological evaluation and repeat coronary

arteriogram may be required.

Exercise Electrocardiography: A standardized protocol such as Bruce treadmill protocol or equivalent

should be employed. The subject should be exercised to symptom limitation and be expected to complete

at least three stages – nine minutes or 11 METs. The reason for discontinuing the test should be recorded

together with the presence or absence of any symptoms.

More than 1 mm ST depressionin Exercise ECG will be considered as positive for reversible

myocardial ischaemia. The depression should be horizontal or down sloping and lasts more than

0.08 second duration. There may be disturbance in conduction or/and ventricular or

supraventricular extrasystoles.

Failure to achieve increase in blood pressure or occurrence of fall in blood pressure is indicative

of extensive ischaemia.

Inability to achieve predicted heart rare target renders the test inconclusive rather than negative.

a. Absence of reversible ischaemia will rule out coronary artery disease.

b. Presence of reversible ischaemia shall have coronary angiogram, and further action will be taken

on the findings.

Coronary Angiogram :Significant stenosis is defined as coronary artery or its main branches being

obstructed more than 30 % and minor branches more than 50 %.

(a) Absence of significant stenosis in any coronary artery or its branches shall be defined as false

positive exercise ECG.

(b) Presence of significant stenosis of one or more coronary artery or braches will be disqualifying.

Applicants with ischaemic damage to the ventricle such as dyskinesia, hypokinesia or akinesia, ejection

fraction <50 and significant abnormality of wall motion shall be assessed as 'unfit'.

3.3.3 Epicardial, myocardial or valvularhear disease: Applicants withepicardial, myocardial or

valvular heart disease, wit or without symptom, treatment or surgery, shall be assessed as unfit.

Applicants without symptom for class II Medical Assessment may be assessed as fit after full

cardiological evaluation and accredited medical opinion, if they are not carrying revenue passengers.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

3.3.4 Vascular conditions: Applicants with following vascular conditions shall be assessed as unfit, viz.

Significant peripheral arterial disease, before or after surgery,

Aneurysm of thoracic or abdominal aorta, before or after surgery, and

3.3.5 Vaso-vagal syncope: Recurrent vaso-vagal syncope will be assessed as unfit.

3.3.6 Rhythm or Conduction Disturbances: Applicant with rhythm or conduction disturbance needs to

be valuated basically to find out (a) what extent of disability it can produce ? and (b) is there underlying

heart disease? This may require detailed cardiological evaluation with echocardiography, exercise

electrocardiogram, Holter monitoring, etc.

Commonly occurring conditions like respiratory arrhythmia, occasional uniform atrial or

ventricular ectopic complexes which disappear on exercise, rapid heart rate from excitement or

exertion, slow heart rate not associated with auriculo-ventricular dissociation, may be regarded as being

within normal limits.

Supra-ventricular premature beats or ectopicsare usually of less importance, but some of them may

predispose to supraventricular tachycardia, atrial flutter or atrial fibrillation.

Supraventricular tachycardia may accompany illnesses like Pneumonia or Thyrotoxicosis, in which

case the disease itself will disqualify him until he is cured or controlled.

Paroxysmal supraventricular tachycardia causedistractionandin some is incapacitating. Applicants

with successful therapy with anti-arrhythmic drugs need not be disqualifying. Ablation therapy should be

confirmed to be successful by repeat electrophysiological studies after 3 months. Restriction is applied as

to fly in multicrew aircraft or to fly with safety pilot for three months, after which the restriction can be

lifted.

Ventricular premature beats in presence of cardiac disease is disqualifying. It is also more likely to be

associated with serious ventricular tachycardia and hence disqualifying if they present with one or more

of the following characteristics :

(a) Prolonged Q-T interval,

(b) Occurrence in close proximity to the vulnerable period i.e R on T phenomenon,

(d) Multifocal origin,

(e) Post-extrasystolic T inversion or post-extrasystolic ST depression, and

(f) Increase in frequency with stress.

It may be assessed as fit with a density of < 200/hour if non-invasive investigations are satisfactory, but

multicrew endorsement is usually applied.

Applicants with broad +/or narrow complex tachycardia shall be assessed as 'unfit'.

Isolated sinus node dysfunction including sinus Bradycardia, may occur in healthy young people,

particularly those engaged in vigorous exercise. Such finding need not disqualify the applicant.

Sinoatrial disease may remain relatively free of symptom for years. Applicant, who is asymptomatic,

may be assessed as fit but with restriction to multicrew operation and regular review with exercise

electrocardiogram for chronotropic incompetence and Holter monitoring are required. Once symptomatic,

he is assessed as permanently unfit.

Atrial fibrillation may be encountered during medical examination. Leaving aside the possibility of

other disqualifying conditions which may coexist, the importance of atrial fibrillation is its possibility to

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

cause distraction, subtle incapacitation and the risk of thrombo-embolism. A single episode with a

defined cause e.g. vomiting, which is self limiting with spontaneous reversion to sinus rhythm eventually

get unrestricted flying status, though in the beginning are endorsed with multicrew status. Need for DC

conversion does not necessarily imply bad prognosis. Other types of atrial fibrillation are paroxysmal or

persistant or permanent atrial fibrillation.. Presence of structural or metabolic abnormality, or of

ischaemic, hypertensive or valvular heart disease, or thyrotoxicosis or possibility of alcohol abuse will

disqualify him from flying. So lone atrial fibrillation, without any obvious pathology may be assessed as

fit with restriction in multicrew operation, if asymptomatic. Permissible medication to reduce the

ventricular rate are Digoxin, Beta blockers and Verpamil.

Fist degree or second degree (Type I) should be investigated to rule out heart disease and to determine

the risk of complete heart block. This can be seen during rest, particularly sleep, in young adults who

engage in vigorous exercise, and so they are assessed as fit without restriction.

Bundle branch block: Isolated bundle branch block and left hemiblocks, which are long standing are

generally benign. Applicants with completeright or left bundle branch block require cardiological

evaluation on first presentation.

3.3.7 Congenital heart diseases: Sometimes applicant with congenital heart disease may apply for initial

or renewal of the licence. The condition may be known earlier or maybe detected for the first time.

Small or early (<24 years) corrected secundum atrial septal defect iscompatible with unrestricted

flying subject to regular review, but departure from this requirement implies restricted flying or denial.

Small ventricular defect may be assessed as fit as it tends close spontaneously or remain stable. Closure

in childhood likewise carries a good outcome.

Coarctation of aorta: Applicant who had undergone surgical correction after the age of 12 is assessed as

unfit due to increased risk of sudden death and incapacitation due to cerebrovascular accident. Applicant

who had undergone successful correction before the age of 12 may be certified fit.

3.3.8 Innocent murmurs: Murmurs not necessarily means a valvular heart disease. If it is diagnosed to

be innocent murmurs, he can be given unrestricted flying status. He may need cardiologist confirmation

with non invasive tests.

3.3.9 ECG Findings: They are listed below in different categories

• Normal Tracing - Fit

• Normal Variant - Fit

• Borderline – Requires evaluation

• Abnormal Tracing – - Unfit straightway or after evaluation

3.4 RESPIRATORY CONDITIONS

Respiratory diseases are the commonest cause of morbidity and loss of time of work in general

population. The disease, not so symptomatic on the ground, may cause problem and incapacitation due to

aviation environment.

3.4.1 Bronchial Asthma: An applicant with recent attack of bronchial asthma shall be assessed as 'unfit

for initial issue of licence. Recurrent attacks shall be assessed as 'unfit for renewal of licence. He may

be considered for certification only after being free from attack for 5 continuous years. History of

childhood asthma alone is not disqualifying.

3.4.2 Chronic obstructive airway disease requiring continuous medications shall be assessed as unfit.

The individual assessment is made on the basis of severity of disease, type and amount of medication

required, full history, pulmonary function test. Treating physician or chest physician's report is usually

required.

3.4.3 Pneumonia: Unfit until fully recovered.

3.4.4 Pulmonary Tuberculosis: Applicant or holder will be assessed as unfit during active tuberculosis

and in the initial phase of treatment at least for two months. Once the patient becomes asymptomatic and

there is marked clearing in the chest X ray, he may be assessed as 'fit' with restriction as only in multi-

pilot aircraft while he is on treatment.

3.4.5 Tubercular Pleural effusion, as in Pulmonary tuberculosis.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

3.4.6 Spontaneous Pneumothorax: It happens suddenly and can cause severe pain or breathlessness.

Open pleurectomy is recommended following a single event and flying duties can be resumed after 3

months after pleurectomy. Otherwise it can be considered for recertification only after 18 months.

Recurrent spontaneous pneumothorax are grounded permanently if pleurectomy is not done.

Investigation to exclude lung disease is required.

3.4.7 Pyothorax: If completely healed after medical +/or surgical treatment, he may be considered for

certification after 6 months. If pulmonary functions are satisfactory, he may be assessed as fit with multi

crew restriction. After one year the restriction may be lifted.

3.5 GASTRO-INTESTINAL CONDITIONS

Digestive complaints or conditions are common in population. These can distract or even incapacitate

though most of them are just a nuisance during the flight.

3.5.1 Gastro-oesophageal reflux disease: If troublesome and symptomatic, it will be assessed as unfit. It

will be assessed as fit after symptom are abated with or without acid suppressing treatment with or

without restriction.

3.5.2 Gastric or Duodenal Ulcer: Active ulcer confirmed on endoscopy are assessed as unfit Before

being assessed as 'fit' ulcer must have healed completely endoscopically. Continued treatment with acid

suppressing agents are allowed, if no side effects are produced.

3.5.3 Complications of ulcer e.g. haemorrhage or perforation: He is assessed as unfit for six months.

After treatment and if asymptomatic, he may be assessed as fit after re-endoscopic confirmation.

Continued treatment with acid suppressing agents are not disqualifying. It may be endorsed with

restricted flying in multicrew operations for six months.

3.5.4. Chronic Inflammatory Bowel Disease: Applicant with chronic inflammatory bowel disease shall

be assessed as unfit.

3.5.5 Cholelithiasis / Cholecystitis: Symptomatic cholelithiasis will be assessed as unfit and will be

assessed as fit only after cholecystectomy and full recovery. Asymptomatic incidental finding of a large

solitary gall stone may be assessed as fit. Acute Cholecystitisare certified unfit and will certified fit after

symptom is controlled after treatment.

3.5.6 Hernia: Significant hernias are disqualifying until they are repaired.

3.6 GENITO-URINARY CONDITIONS

3.6.1 Haematuria: An initial applicantwithhaematuria should be investigated before final assessment is

given. Others who are found to have isolated microscopic haematuria during routine medical

examination, may be assessed fit while further investigations are carried out. In case of frank

haematuria, licence is suspended or medical assessment result is withheld until the investigations are

completed.

3.6.2 Proteinuria: Trace protein result can occur in as little as 50 mg of protein in a litre of urine and 1+

at about 300 mg in a litre of urine. On finding 1+ proteinuria, one should get 24 hours excretion of

protein in urine. An applicant forinitial licence with proteinuria should be investigated before final

assessment is given. Applicants for renewal and licence holders with isolated mild proteinuria (<1 gm in

24 hours may continue to fly) whilst awaiting investigations may be allowed full flying duties without

restrictions. If Significant proteinuria (>1 gm in 24 hours) is found, medical licence result is withheld or

licence suspended pending the results of investigations. If associated with haematuria, hypertension, renal

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

impairment or signs of systemic disease, he should be assessed as unfit. If proteinuria is isolated finding,

he may be assessed as fit with restricted multicrew operations, provided that he is carefully followed up

at a minimum of six monthly intervals.

3.6.3 Urolithiasis: Urolithiasis or stone in the urinary tract is a common condition in the general

population. The concern is the sudden incapacitation due to colic that it can produce. Once the applicant

or holder is suspected of or diagnosed urolithiasis, further urological evaluation is mandatory. The stone

may pass per urethra or removed by extracorporeal shockwave lithotripsy (ESWL) or operation, but it

can recur in course of time. Hence follow up is important.

Urological evaluation are , as follows:

Full history including family history

Urine examination - routine and microscopic examination

Blood examination – urea, creatinine, electrolytes, calcium, uric acid

Intravenous urogram (IVU)

Ultrasound of abdomen and pelvis

Biochemical tests

Other tests as deemed necessary

Asymptomatic stone: Any stone in urinary tract, even without symptom will require further evaluation.

 If it is lying in the parenchyma and causes no obstruction, he may be certified fit without

restriction.

 If it is lying in collecting system with or without obstruction, his licence is suspended until the

stone is cleared. Ultrasound of abdomen and pelvis will be required in every medical assessment.

Symptomatic Stone: If the stone is causing colic pain, his licence is suspended until the stone is cleared.

Recurrent Stone: It is important to follow up closely for recurrence of stone by means of ultrasound in

each medical examination.

3.7 METABOLIC, NUTRITIONAL AND ENDOCRINAL CONDITIONS

3.7.1 Obesity : Gross obesity, BMI of more than 40, will be assessed as unfit for all classes of medical

assessments. Obesity, BMI more than 30, in an applicant will require further evaluation especially for

risk factors of cardiovascular diseases and obesity- associated health problems, before he is assessed as

fit. He also may required to be tested in the aircraft and cockpit about his movement and activities to

operate the aircraft.

3.7.2 Serum lipids abnormality: Serum lipids estimation (serum cholesterol, triglyceride, HDL &

LDL): The concern with disturbance of lipid metabolism is accelerated atherogenesis and so potential

increase in the risk of sudden cardio-vascular incapacitation in the aviation personnel.

The serum lipids estimation is to be done in the fasting stage. All the lipid components are to be

maintained within normal limits. It is even more important in presence of hypertension and /or coronary

artery disease and family history. In such cases and in presence of other risk factors, it is to be

maintained at further lower level, which are to be controlled by life style modification e.g. reduction in

alcohol, cessation of smoking, and increased exercise. If lipids do not come down to satisfactory level in

two periods of 3 months on non-pharmacological means, Statin medication are to be started.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

On the start of medication the license holder shall not be allowed to exercise the privilege of his licence

to insure that it has not caused significant side effects. During renewal lipid profiles will be required.

Lipid profile abnormality alone will not downgrade his medical fitness.

3.7.3 Diabetes: Diabetes mellitus is a common condition in the population and half of them remain

undiagnosed and the incidence is on the rise in this part of the world. So it is also found in the aviation

personnel. The problems in the aviation could be from diabetes as well as from its associated

complications e.g. marked increase in coronary artery disease, visual problems and nephropathy. The

other problem is from the treatment causing hypoglycaemia which can be severe and sudden or mild and

subtle. Both are serious hazards to flight safety.

Glycosuria found at 'Medical Examination' or at any other time requires that the license be suspended

until full investigation has been undertaken.

Should a diagnosis ofImpaired glucose tolerance (IGT) or Diabetes be made, the license must remain

suspended until stable control is achieved from diet +/- approved oral antidiabetic agents and maintained

for three consecutive months.

Typical symptoms of diabetes mellitus are weight loss, polyuria and polydypsia. Finding of glycosuria

and an elevated blood sugar are diagnostic. However, the difficulty arises from mild glycosuria and

subsequent abnormal blood glucose levels are found in a symptomless applicant during routine medical

examination. Abnormal blood glucose requires glucose tolerance testing.

Diabetes may be controlled on diet alone or oral antidiabetic agents or insulin may be required depending

on the type and severity of diabetes.

Should diabetes control be obtained satisfactorily by modification of diet alone, all classes of license

are restored.

Diabetes controlled by anti-diabetic agents, Metformin or Acarbose, will be assessed as fit.

Once diagnosed as impaired glucose tolerance or diabetic he should be on regular follow up under a

diabetologist or physician and should provide the report from him during the medical examination. All

cases of impaired glucose tolerance or diabetes on control with diet or approved oral antidiabetic agents

for consecutive three months will be endorsed with restriction to multicrew aircraft for one year, and then

after restriction will be removed if maintained on satisfactory control. Continued licence will necessitate

regular medical monitoring and maintenance of satisfactory blood sugar level, freedom from ketonuria

and glycosuria and that cardiovascular, neurological, renal and ophthalmological states remain normal. In

medical examination for renewal of licence, he will have urine routine and microscopic examination, 2

hours blood sugar after glucose load and Glycosylated haemoglobin, which should be in acceptable limit.

He also should provide a report from his doctor. Once a year they will have Exercise ECG test

andfundoscopic examination after pupil dilatation.

Failure of control of diabetes will suspend the licence. Frequent failure to maintain the control of

diabetes may be assessed as unfit permanently.

Should diabetes control be obtained only by the use of sulphonylureas or insulin, he will be assessed

as 'unfit.'

Diabetes with overt complication, though under control, will be assessed as permanently unfit.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

Glucose Tolerance Test:75 G of glucose loading in a minimum of 250 ml of water is given to a fasting

subject who has eaten a normal diet containing not less than 250 G of carbohydrate for the previous few

days. Normal activities during those three days and rest for half an hour before test. No further activities

until the test is completed.

No smoking in the morning and during the test. Test is to be done before 10 AM, preferably.

duties and continued licensing.

Hyperthyroidism: Once diagnosed and confirmed by thyroid function tests, his licence will be

suspended and he will be given appropriate treatment ( medical or radio-active iodine or surgical) under

the care of an endocrinologist or physician. After maintenance of euthyroid state including normal

thyroid function tests for sufficient length of time i.e. not less than 3 months and with good range of eye

movements and no diplopia, he will be assessed as medically fit with restriction to operate in multi crew

aircrafts for one year and subsequently the restriction will be lifted. The licence will, however, be

dependent upon continuing periodic review with thyroid function tests and a medical report of the

treating physician throughout the flying career.

Hypothyroidism: Similarly on being diagnosed and confirmed by thyroid function tests, his licence will

be suspended. He will be given Thyroxine under the care of an endocrinologist or physician. After

maintenance of euthyroid state including normal thyroid function tests for sufficient length of time i.e.

not less than 3 months, he will be assessed as medically fit with restriction to operate in multi crew

aircrafts for one year and subsequently the restriction will be lifted. The licence will, however, be

dependent upon continuing periodic review with thyroid function tests and a medical report of the

treating physician throughout the flying career,

3.7.5 Pregnancy: Though pregnancy is a normal physiological process, it causes major anatomical and

physiological disturbances and stress in the system which are associated with increase in incapacitation.

During the first trimester the chances of abortion are there, and till 20 weeks of pregnancy bleeding per

vagina and crampy abdominal pain can occur. Pregnancy is to be confirmed as early as possible and

thenafter she should have regular anti-natal care. After 26 weeks there can occur gastro-intestinal

disturbances due to hormonal change and anatomical displacement. Even fetal movement in the womb

can be discomforting and distracting. Hence she should be under monthly obstetrical assessment and only

after the clearance from that assessment she should be allowed to continue to privilege of the licence.

She also should be able to consider disqualified herself in presence any discomfort or symptom. They are

faintness, dizziness or vertigo, nausea or vomiting, anaemia (Hgb<10 G %), glycosuria or proteinuria,

urinary tract infection, vaginal bleeding, abdominal pain, high blood pressure, etc.

In general, it is advisable to suspend the licence in the first trimester and after 26 weeks of pregnancy.

Obstetrician's report is necessary.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

The flight crew should be informed of the hazards of low pressure and radiation to the fetus during flight.

4 – 6 weeks after confinement or termination of pregnancy, she should have medical examination and

assessment to confirm involution has taken place before she resumes her duties.

3.8 MUSCULO-SKELETAL CONDITIONS

Musculo-system is concerned for stability, power, movement and activities. Any significant deficiency

can be a threat to flight safety. If any doubt exists, he should be tested in actual aircraft during access and

exit, in use of controls during flight, and in emergencies and evacuation under the instructor.

3.8.1 Upper Limb: Good range of joints movement, power and dexterity of upper limbs are required in

the flight crew in order that aircraft controls, which are positioned not only in front of but also to the side

of, and above the seat, can be reached and used.

Injury of the upper limbs are common in the young age due to accidents and sport activities. Traumatic

dislocation of shoulder joint or gleno-humeral joint in a crew will disqualify him from flying. Only

after 8 - 10 weeks of reduction and rehabilitation and full activities he may return to full flight status. In

theses cases recurrent dislocation can often follow. In that case only after surgical repair and full recovery

of function he may be assessed as fit initially with restricted operation in multicrew aircrafts and later

cleared for solo flights. Clavicularfracture, disruption ofacromio-clavicular joint, and rotator cuff

injuryalso ground him temporarily.

Elbow movements, functionally speaking are complimentary to those of shoulder complex and therefore

some reduction of elbow flexion and extension in acceptable. But restriction of forearm rotation,

whether it is as a result of elbow condition, malunion of old forearm fracture or disruption of radio-

ulnar joint is unacceptable.

Ability to perform three basic types of activity of grasping, pinching and hooking are fundamental to

normal hand function. These three movements with normal coetaneous sensibility are essential for the

safe manipulation of aircraft controls. Limitation of movement of the joints, painful condition,

weakness and lack of sensation due to nerve lesion will suspend the licence. Freedom of symptoms at

least for six months is required before it is considered for assessment regarding fitness for flight duty

3.8.2 Lower Limb: Adequate lower limb function e.g. stability, power and adequate range of movement,

is essential for access and exit of the aircraft and safety in flight. Limitation of flexion in hip joint to less

than 90 degrees from neutral position from any cause is considered hazardous. Similarly painless range of

movement of knee of at least 90 degrees of flexion from fully extended position is required. Almost full

range of painless and stable movements of jankle and subtalar joints are required for the safe control of

the aircraft. Presence of unbalanced paralysis or weakness andfootdropas a result of the first sacral root

involvement due to disc prolapse, can result in an inability to control aircraft safely

3.8.3 Thoraco-lumar Spines: Low back ache are common symptom in young age group and more so in

helicopter pilots. When they have symptom, they should be grounded until they become symptom free.

Lumbar disc lesions are common and can be disabling. Those with sciatica due to disc prolapse may

have to undergo surgical treatment. Lesser degree of slip disc, grade I and those who had single level

spine fusion to control the symptom are considered fit for unrestricted flying role. Higher grades of slip

disc are usually disqualifying as they are associated with higher incidence of neurological abnormalities.

3.9 EAR, NOSE & THROAT CONDITIONS

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

Drum Perforation: A single dry perforation is acceptable. An acute perforation will result in being unfit

until hearing and tympanic membrane recovers.

Otitis media: Unfit until fully recovered.

Sinusitis: Unfit until fully recovered

Vertigo: Vertigo or giddiness is a common experience to many and usually it is transient and of no

consequence. Persisting and recurring vertigo in incompatible to safe flying.

Recurrent vertigo due to paroxysmal vestibular disorder and benign positional vertigo is assessed as

permanently unfit as it is recurring symptom. But in case of acute vestibular disturbance where the cause

is thought to be due to a transient disorder of the peripheral labyrinth with full recovery with normal

neurological assessment, he may be certified fit without restriction. Meniere's Disease is disqualifying,

but the diagnosis must be confirmed.

Monoaural hearing or loss of hearing in one year is disqualifying in all classes of licence.

Hearing Aid is not acceptable in all classes of licence.

Post-Surgical conditions: Though chronic or sequelae of the diseases of the ear are disqualifying, after

surgical treatment he may be considered if he has regained the function and is observed for certain length

of time. Applicant with simple myringotomywill be assessed as fit for all classes without restriction

after one month of observation, if the middle ear is dry, tympanic membrane healthy, and hearing is

normal and there is no vertigo. After simple mastoidectomy he may be assessed as fit if the ear

examination including hearing is normal and wound is healed. Tympanoplastydone for closure

perforation of ear drum also improves the hearing. If the hearing is satisfactorily recovered and ear drum

is intact and healthy, he may be assessed as fit without restriction in all class of licence after one month.

Otosclesrosis is a common cause of conductive deafness in adults. But after ear surgery viz.

Fenestration operation, Stapes immobilization operation, Stapedectomy with prosthesis

implantation, he may be considered for recertification if specialized ENT examination after three

months of operation finds satisfactory hearing, patent eustachian tube, no vertigo, no nystagmus and

unsteadiness on Valsalva manoeuvre or forceful nose blowing. It will be restricted to fly as or with

another co-pilot or safety pilot for two years observation period. After that period the restriction may be

removed.

3.10 EYE CONDITIONS

3.10.1 Poor vision: The applicant having poor vision, worse than 6/60 unaided, can get vision to 6/9 in

each eye with high refractory error correction may be considered for recertification. They should wear

either contact lens or high-index spectacle lenses.

3.10.2 Diseases of eye and adnexa cause visual or distracting ocular symptoms which in flight crew pose

flight safety issues. The presence of active disease of eyes or adnexa will be assessed as unfit temporarily

or suspend the licence until the condition has been cured or stabilized and is deemed unlikely to be a

safety hazard or recur. He may be assessed as fit initially in dual pilot category.

3.10.3 Cataract: A stationary cataract, or lens opacity, either congenital or acquired, if it does not

interfere with the vision, may be assessed as fit in trained flight crew and need not impose restrictions.

The cataract which interferes with the vision, orpresenile cataract, idiopathic or acquired, requires

temporary grounding and ophthalmic intervention. Ppseudophakia (intra-ocular lens implanted) is

certified fit provided all visual requirements are me, with or without correction, after three months of

surgery and refraction had remained stable on two occasions at the interval not earlier than three months.

CIVIL AVIATION AUTHORITY OF NEPAL

Medical Requirements, Fourth Edition, October 2016

3.10.4 Symptomless heterophoria is considered no bar for flying status depending on the magnitude of

deviation and degree of control, but manifest squint or heterotropia are assessed as unfit for flying.

3.10.5 One eye or monocular vision: A flight crew with one eye or monocular vision is assessed as

unfit.

3.10.6 Corneal and refractory surgery: Applicant with corneal and refractory surgery will be

assessed as fit only if following conditions are met during each medical examination.

 All the eye drops should have be withdrawn not less than six months.

 Visual acuity shall meet the required standards.

 Refraction and visual acuity must remain stable on two consecutive measurements at the

difference of three months, six months after surgery.

There should be no ongoing treatment of the eyes.
