Class 2 Medical Certificate Hong Kong: Complete Guide 2025

A detailed guide to obtaining and maintaining a Class 2 Medical Certificate in Hong Kong, covering requirements, the examination process, costs, renewal, and links to pilot licensing.

Before you can solo an aircraft or earn a Private Pilot Licence (PPL) in Hong Kong, you must hold a valid medical certificate. For most recreational and private pilots, that means a Class 2 Medical Certificate. Issued by the Hong Kong Civil Aviation Department (CAD) or a designated aviation medical examiner (AME), this certificate proves you meet the medical standards necessary to fly safely. Without it, your logbook remains empty, no matter how many hours you have studied or how much you have spent on ground school subjects.

This article explains everything you need to know about the Class 2 Medical Certificate in Hong Kong: eligibility, the examination process, common pitfalls, costs, renewal timelines, and how it fits into your broader journey toward a PPL or even a Commercial Pilot Licence. Whether you are a complete beginner or an experienced pilot returning after a break, understanding the medical certificate is a critical first step.

What Is a Class 2 Medical Certificate?

A Class 2 Medical Certificate is the minimum medical standard required to exercise the privileges of a Private Pilot Licence (PPL) in Hong Kong. It is also required for a Student Pilot Licence (SPL) and for certain other recreational flying activities. The certificate is issued under Hong Kong Civil Aviation (Personnel Licensing) Regulations, which align closely with International Civil Aviation Organization (ICAO) Annex 1 standards.

There are two main classes of medical certificate in Hong Kong:

Class 1 Medical Certificate, required for Commercial Pilot Licence (CPL) and Airline Transport Pilot Licence (ATPL) holders. Stricter standards apply, especially for vision, cardiovascular health, and hearing.
Class 2 Medical Certificate, required for PPL, SPL, and some recreational licences. Standards are less stringent but still comprehensive.

For a detailed comparison of the two, read our article on medical certificate class 1 vs 2. If you are aiming for a career as a professional pilot, you may eventually need a Class 1, but for most hobbyists and private flyers, the Class 2 is sufficient.

Who Needs a Class 2 Medical Certificate in Hong Kong?

You need a Class 2 Medical Certificate if you are:

Applying for a Student Pilot Licence (SPL), the first licence you get before you can fly solo.
Applying for or renewing a Private Pilot Licence (PPL), for fixed-wing or helicopter.
Flying as a non-commercial pilot on a Hong Kong-registered aircraft.
Undertaking flight training at a Hong Kong flight school that requires a valid medical before first solo.

Even if you are just beginning your journey and reading our complete guide to learning to fly and general aviation in Hong Kong and the region, you should arrange your medical examination early, ideally before you start ground school. A medical condition discovered later could delay or end your training.

Medical Standards for Class 2 Certificate

The Hong Kong CAD follows ICAO standards but may impose additional requirements. The key areas assessed are:

Vision

Distance visual acuity: Must be at least 6/9 in each eye separately, with or without correction. If you wear glasses or contact lenses, your corrected vision must meet this standard, and your uncorrected vision must be at least 6/60 in each eye.
Near vision: Must be able to read N5 (approximately 0.5 m) and N14 (approximately 1 m) with or without correction.
Colour vision: Must be able to correctly identify aviation signal colours (red, green, white). Testing is usually done with Ishihara plates or a colour vision lantern.
Binocular function: Normal binocular field of vision and no diplopia (double vision).

Hearing

Hearing loss must not exceed 35 dB at any of the frequencies 500, 1000, or 2000 Hz, and not more than 50 dB at 3000 Hz, in the better ear.
If you fail the pure-tone audiogram, you may still pass with a speech discrimination test or a practical test of hearing in a noisy environment.

Cardiovascular

No history of coronary heart disease, significant arrhythmia, or other conditions that could cause sudden incapacitation.
Blood pressure must be well-controlled, typically below 155/95 mmHg on examination. Higher readings may require further investigation or a period of monitoring.
An electrocardiogram (ECG) is required for initial issue if you are aged 40 or over, and for renewals from age 50 onward.

Other Medical Conditions

Diabetes: Well-controlled diabetes (Type 2) is usually acceptable. Insulin-dependent diabetes may require special assessment.
Mental health: Any history of psychosis, severe depression, or substance dependence may be disqualifying unless fully resolved and stable for a period determined by the AME.
Neurological: Epilepsy, recurrent seizures, or unexplained loss of consciousness are generally disqualifying unless a specialist confirms a low risk.
Medications: Many common medications (e.g., some antidepressants, blood thinners, or sedatives) may affect your fitness to fly. You must declare all prescription and over-the-counter drugs.

If you have any chronic condition, it is wise to consult an AME before starting training. The eligibility requirements for Hong Kong include medical fitness as a core component.

The Examination Process in Hong Kong

Step 1: Find an Authorised Aviation Medical Examiner (AME)

Only doctors approved by the Hong Kong CAD can conduct Class 2 medical examinations. The CAD publishes a list of AMEs on its website. As of 2025, there are approximately 15-20 AMEs in Hong Kong, most based at private clinics in Central, Admiralty, Wan Chai, and Kowloon. Some AMEs also operate at the Hong Kong Aviation Club (HKAC) in Shek Kong.

You should book an appointment directly with an AME. Expect a wait of 1-3 weeks, depending on the clinic. The examination takes about 1-2 hours.

Step 2: Prepare the Required Documents

Before your appointment, gather:

Your Hong Kong Identity Card (HKID) or passport.
A completed CAD medical history form (available from the CAD website or your AME).
Any relevant medical reports, including specialist letters, hospital discharge summaries, or recent blood test results if you have a chronic condition.
Your current glasses or contact lenses prescription, if you wear them.
A list of all medications you take, with dosages.

If you have had a previous medical certificate (from any country), bring a copy.

Step 3: Undergo the Examination

The AME will perform:

General physical examination (height, weight, pulse, blood pressure, heart, lungs, abdomen).
Vision tests (visual acuity, near vision, colour vision, field of vision).
Hearing test (pure-tone audiogram).
Urine test (for glucose, protein, and blood).
ECG if you are 40 or over (or earlier if indicated).
Blood tests (haemoglobin, fasting glucose, cholesterol), not always routine but may be requested.

The AME may also ask about your lifestyle: smoking, alcohol consumption, exercise, and stress levels. Be honest, withholding information can lead to revocation of your certificate later.

Step 4: Receive Your Certificate

If you pass all tests, the AME will issue a CAD medical certificate form (CAD 339) on the spot or within a few days. The certificate is valid for:

12 months if you are under 40 years of age.
6 months if you are 40 or over.

The certificate is sent to the CAD for recording. You will receive a copy for your logbook and records. Keep the original in a safe place, you must present it when applying for or renewing your licence.

Cost of a Class 2 Medical Examination in Hong Kong

As of 2025, the typical cost for a Class 2 medical examination with a Hong Kong AME ranges from HK$2,500 to HK$4,500. This includes the consultation, basic tests (vision, hearing, urine, blood pressure), and the certificate fee. Additional tests, such as ECG (HK$800, HK$1,200), blood tests (HK$500, HK$1,000), or specialist referrals, are extra.

Some health insurance plans in Hong Kong cover part of the cost if you have outpatient coverage, but medical certificate examinations are often excluded. Check with your insurer.

For comparison, a Class 1 medical examination costs roughly HK$4,000, HK$7,000, reflecting the more extensive tests required. Read our realistic cost of PPL in Hong Kong article to see how the medical fits into your total training budget.

Common Reasons for Failure or Deferral

Most applicants pass their Class 2 medical without issue. However, the following conditions commonly cause delays or denial:

Uncorrected vision below 6/60 in either eye, even if corrected vision is good, the uncorrected standard must be met.
Colour vision deficiency, mild colour blindness may pass with a lantern test, but moderate-to-severe deficiency is disqualifying for a PPL.
High blood pressure, readings above 155/95 at the time of exam may lead to a deferral until the condition is treated and stable.
Elevated blood sugar, undiagnosed diabetes or poor control can halt the process.
Use of disqualifying medications, for example, some benzodiazepines, strong painkillers, or certain antidepressants.
History of epilepsy or seizures, even a single childhood febrile seizure may require a specialist report.

If you are deferred, the AME will explain what further tests or reports are needed. You can usually reapply once the condition is resolved or stabilised. The CAD may issue a restricted medical certificate (e.g., requiring a safety pilot) in some cases.

Renewal and Validity

Your Class 2 Medical Certificate has a fixed validity period. To maintain your licence privileges, you must renew before the expiry date. The renewal process is similar to the initial examination, though you may not need all tests if your health is unchanged and you are under 40.

Renewal costs are typically slightly lower than initial examination (HK$2,000, HK$3,500) because some paperwork is already on file. However, if you are 40 or over, an ECG is mandatory for renewal every two years.

Important: If your medical certificate expires, your pilot licence becomes invalid immediately. You cannot fly until you have a new certificate. Plan your renewal at least 4-6 weeks before expiry to avoid gaps.

Class 2 Medical and the Path to a PPL

For aspiring private pilots, the Class 2 Medical Certificate is one of the first formal steps. You should obtain it before you begin flight training, because:

Flight schools in Hong Kong require a valid medical before you can solo, typically after 10-20 hours of dual instruction.
If you discover a disqualifying condition after spending HK$50,000, HK$100,000 on training, you may not be able to complete your licence.
The medical certificate is a prerequisite for the HK CAD licensing process.

Many students choose to take their medical during the self-study period before ground school so that everything is ready when they start flying. This also gives time to address any minor issues (e.g., getting new glasses or adjusting blood pressure medication).

If you later decide to pursue a commercial career, you will need to upgrade to a Class 1 Medical Certificate. The transition is not automatic, you must undergo a separate examination with stricter standards. Our article on cadet medical standards explains what airlines look for in professional pilot candidates.

Flying with a Class 2 Medical Certificate Outside Hong Kong

Your Hong Kong-issued Class 2 Medical Certificate is recognised by most ICAO member states for the purpose of flying a Hong Kong-registered aircraft. However, if you plan to fly an aircraft registered in another country (e.g., a US-registered N-number or a UK-registered G-number), you may need a medical certificate issued by that country’s aviation authority.

Some countries, such as the United States, accept a foreign medical certificate for a limited period (e.g., 90 days) for visiting pilots. Check with the local aviation authority before you travel. For pilots flying in mainland China, the CAAC has its own medical standards, and a Hong Kong certificate alone may not suffice.

If you are training abroad, for example, at a flight school in Australia, Canada, or the United States, you will typically need a local medical certificate (e.g., a US FAA Third Class Medical or an Australian CASA Class 2). However, many schools accept a Hong Kong Class 2 for initial training if you are enrolled in a Hong Kong CAD-approved programme. Always confirm with the school before you travel.

Tips for a Smooth Medical Examination

Schedule your exam for the morning, blood pressure tends to be lower, and you can fast for any blood tests.
Avoid caffeine, alcohol, and heavy meals for 12 hours before the exam.
Bring your glasses or contact lenses, even if you do not normally wear them for distance, the AME will test both corrected and uncorrected vision.
If you have a known condition (e.g., high blood pressure, diabetes), bring recent test results from your regular doctor.
Be honest about your medical history. The AME is there to help you fly safely, not to disqualify you unnecessarily.
If you are deferred, ask for a written explanation and a list of steps needed to meet the standards. Most conditions are manageable with time and proper treatment.

Frequently Asked Questions

Can I fly while my medical certificate application is pending?

No. You must hold a valid medical certificate before you can exercise the privileges of any pilot licence. If your certificate has expired, you cannot fly until the new one is issued.

What if I fail the colour vision test?

You may request a secondary test using a colour vision lantern (e.g., the Farnsworth lantern or the Holmes-Wright lantern). Some AMEs in Hong Kong have these devices. If you still fail, a restricted medical certificate may be possible, but only for daytime VFR flight, not for night flying or any activity requiring colour signal recognition.

How long does it take to get the certificate after the exam?

If you pass all tests, the AME can issue the certificate immediately or within 1-2 working days. The CAD will then send you an official record within 2-4 weeks. You can start flying as soon as the AME gives you the signed certificate.

Do I need a medical certificate for a glider or balloon licence?

Yes, the same Class 2 medical standard applies for a PPL (glider) or PPL (balloon) in Hong Kong.

Can I use a Class 2 medical from another country in Hong Kong?

Generally, no. The Hong Kong CAD requires a medical certificate issued by a Hong Kong AME. However, if you hold a foreign licence that has been validated by the CAD, your foreign medical may be accepted for the duration of the validation. Check with the CAD Licensing Section.

Conclusion

Obtaining a Class 2 Medical Certificate is a straightforward but essential step for anyone who wants to fly in Hong Kong. The process is designed to ensure that pilots are medically fit to operate aircraft safely, without compromising public safety or their own well-being. By understanding the standards, preparing for the examination, and staying on top of renewals, you can keep your medical certificate valid and your flying career on track.

Whether you are just starting out or are an experienced private pilot, the Class 2 medical is your ticket to the skies. Combine it with thorough ground school, consistent flight training, and a commitment to safety, and you will be well on your way to earning your wings.
