What should be done if a pilot feels fatigue during a flight?

Following the procedures outlined in the Flight Operations Manual (FOM) for fatigue management is the proper course of action when a pilot feels fatigue during a flight. This is crucial because fatigue can significantly impair a pilot's performance and decision-making abilities, increasing the risk of incidents and compromising safety. The FOM provides specific guidelines aimed at identifying, managing, and mitigating fatigue to ensure that operations are conducted safely and effectively.

The FOM procedures may include protocols for reporting fatigue, possibly reallocating duties, or even considering a diversion if the pilot's ability to operate the aircraft is compromised. Adhering to these procedures ensures that the safety of the flight is prioritized and that decisions are made in accordance with established safety practices.

Other approaches, such as continuing to fly despite fatigue, taking a nap without informing anyone, or simply reducing flight speed while operating normally, would not be in line with safety standards or best practices. These alternatives could lead to dangerous situations due to impaired judgment or lack of adequate communication and support within the crew.
