Pilot obligations for managing fatigue risk
Pilots must take steps to manage fatigue risk, including the possible decision not to operate an aircraft if they feel that they are unfit as a result of fatigue, or likely to become so. There are various obligations for pilots to do this under CAO 48.1 Instrument 2019.
It is a condition on each flight crew licence that the licence holder must not operate an aircraft if, considering the circumstances of the flight to be undertaken, a reasonable person in the pilot’s position would consider that he or she is suffering from, or is likely to suffer from, fatigue which may so impair performance that the safety of the operation may be affected.
A pilot employed by an operator must, before any flight duty period (FDP), disclose to the operator any matter that a reasonable person in the pilot’s position would consider likely to adversely affect his or her ability to meet the operator’s fatigue risk management policies; or the limits and requirements of the appendix or appendices that the holder has chosen to apply to the pilot.
Detailed guidance to meet these obligations is provided in CAAP 48-01 v3.2 (pdf 1.13 MB) - Fatigue management for flight crew members.
