Aviation safety depends on sound aircraft and a capable crew, but a pilot's health is fundamental to both. Strict aviation medical examinations, governed by EASA Part-MED, ensure that pilots are fit to carry out their duties safely. Medical certificates are divided into classes; the two most important are Class 1 for commercial pilots and Class 2 for private pilots. Although both serve the same purpose, they differ in key respects that reflect different levels of risk and responsibility.
Who is who in the cockpit? Class 1 for professionals, Class 2 for enthusiasts
The main difference between the certificates is what they are required for.
- Class 1 medical certificate is required for commercial pilots working towards a CPL (commercial pilot licence) or ATPL (airline transport pilot licence). It is the gold standard for people who plan to make a career of flying commercially and carrying passengers. The requirements are strictest because the risk of a commercial pilot becoming unfit to fly is unacceptable.
- Class 2 medical certificate is required for student pilots and holders of a private pilot licence (PPL) who fly for recreation rather than commercially. The standards are less demanding, reflecting the lower risk profile of private flying.
How often do you need to see an aviation medical examiner? Certificate validity
The frequency of medical examinations depends directly on the pilot's age and licence. The higher the operational risk (Class 1) and the older the pilot, the more frequent the examinations.
| Licence holder's age | Class 1 (CPL/ATPL) – validity | Class 2 (PPL) – validity |
|---|---|---|
| Under 40 | 12 months | 60 months (5 years) |
| 40–49 | 12 months (6 months for single-pilot commercial operations) | 24 months (2 years) |
| 50–59 | 12 months (6 months for single-pilot commercial operations) | 12 months (1 year) |
| 60 and over | 6 months | 12 months (1 year) |
The table shows that commercial pilots must renew their medical certificates every year (or every six months after the age of 60), while a younger private pilot's certificate can remain valid for as long as 5 years. After the age of 40, however, private pilots need examinations much more often, reflecting the regulator's attention to age-related changes in health.
Eyesight, heart and hearing: the key examinations
Although the examination covers the whole body, the differences between classes are particularly clear in some areas.
Eyesight: a crucial test for commercial pilots
Eyesight requirements are among the most challenging to meet, especially at an initial Class 1 examination.
- Refractive error – at their first examination, a candidate for a commercial pilot licence must not have a refractive error greater than -6.00 dioptres for short-sightedness or +5.00 dioptres for long-sightedness. Astigmatism must not exceed 2.00 dioptres. These strict limits are intended to eliminate the risk of retinal disease, which is more common with a high refractive error. Class 2 standards are much less restrictive and focus mainly on achieving the required visual acuity with correction.
- Colour vision – Class 1 candidates must pass rigorous tests, including a lantern test if they do not pass the Ishihara plates. This ensures that they can distinguish lights and indicators accurately in all conditions.
Heart and hearing tests
Commercial pilots also undergo more frequent and more detailed checks in these areas.
- ECG – for Class 1, an ECG is compulsory at the initial examination and is repeated regularly according to age. For Class 2, it is required much less often: at the initial examination and then only after the ages of 40 and 50.
- Audiometry – pure-tone audiometry is standard for Class 1 every few years. For Class 2, it is required only if the pilot wants to obtain an instrument rating (IR), an example of medical requirements being adapted to the increasing operational risk.
How to prepare for your medical examination: useful tips
Every pilot candidate, especially anyone planning a professional career, should take a considered approach to their health.
- Take your Class 1 medical early. If you plan to pursue a career in aviation, do not put off your initial Class 1 medical. Finding out early whether you meet the strict criteria (particularly for eyesight) can prevent disappointment and unnecessary investment in training.
- Keep track of your certificate's validity. If a medical certificate has been expired for more than 2 years, you will need to undergo another examination as an initial applicant, under stricter standards.
- Manage any health conditions proactively. If you have been diagnosed with a chronic condition, take an active role in managing your health and keep your medical records in order. Your discipline and sense of responsibility are key to obtaining and retaining a licence.
