Medical certificate

Flight crew licence CASR 61.405, 61.410

Generally speaking, unless you have obtained permission from CASA, you must not perform any duty authorised by your licence unless you hold a current aviation medical certificate (CASR 61.405–61.415).

There are different types of aviation medical certificates.

  • The Class 1 medical certificate demands the highest of medical standards as set out in CASR 67.150. A pilot must hold a Class 1 medical certificate to fly most commercial operations. A Class 1 medical certificate will also authorise the conduct of private and recreational flying operations (CASR 61.415).
  • The Class 2 medical certificate allows for private flying operations and will also allow for recreational flying operations (CASR 61.410). It also allows commercial operations where no passengers are carried.
  • A Basic Class 2 medical certificate is an alternative to a full Class 2 certificate for private operations. It has the following operational restrictions:
    • private operations by day under the visual flight rules (VFR) and below 10,000 feet
    • a maximum of five passengers
    • piston engine aircraft
    • maximum take-off weight (MTOW) of less than 8618kg
    • no use of operational ratings (eg. instructor rating, instrument rating)
    • no use of flight activity endorsements (eg. aerobatics, low level).

The period for which a medical certificate remains in force depends on the age of the pilot and the kind of medical certificate in question, but may be varied for other reasons (CASR 67.205, 67.210-67.220).

Obligation to tell CASA of changes in medical condition CASR 67.265

You must not fly if your ability to act efficiently is, or is likely to be, impaired due to illness or injury, no matter how minor it is.

Additionally, if you hold a private pilot licence or radiotelephone operator licence and the impairment lasts for 30 days or more, you must not fly until a designated aviation medical examiner (DAME) certifies that the impairment no longer exists. The above period is reduced to seven days for commercial pilots (CASR 67.265).

Suspension of medical certificate due to pregnancy is contained in CASR 67.235.


Over-the-counter or prescribed medication/drugs may reduce your ability to function properly while flying. Search for ‘testable drugs’ at, or talk to an aviation medical professional.

Drug and alcohol management plans CASR Part 99

Piloting an aircraft is a safety-sensitive aviation activity and pilots must comply with the requirements of CASR Part 99 in relation to drugs and alcohol. CASR Part 99 establishes a regime for random drug and alcohol testing conducted for, or on behalf of, CASA of all pilots in Australia.
