What is a Class 3 medical certificate for air traffic controllers?

A Class 3 medical certificate is the medical standard used for air traffic controllers in many European regulatory systems. It confirms that a controller or trainee meets the medical fitness requirement for safety-critical ATC duties.

What gets checked: Under EASA-style rules, Class 3 is linked to student air traffic controller and air traffic controller licensing. Other regions may use different names, but the purpose is similar: proving that the person is medically fit to control traffic safely.

The assessment can include vision, colour perception, hearing, cardiovascular health, neurological fitness, mental health and other checks relevant to controller performance. The examiner is looking for conditions that could impair concentration, communication, judgement or create a risk of sudden incapacitation.

Validity depends on the authority and age. Under EASA Class 3 rules, the certificate is normally valid for 24 months under age 40 and 12 months from age 40. A shorter validity or limitation may be applied if medical follow-up is needed.

Because medical results can affect eligibility, ATC candidates should complete the official medical process through the relevant authority or approved examiner rather than relying on generic advice.

Class 3 is not a pilot medical class. Pilots normally use Class 1, Class 2 or other pilot medical standards depending on the licence and authority. ATC medical standards are built around controller-specific risks such as sustained concentration, hearing, colour perception and sudden incapacitation.

If a limitation is added, it may restrict how or when the person can work. The limitation must be compatible with the unit's operational requirements before the controller can perform live duties.
