Who holds the responsibility to determine if a pilot is fit to fly despite having a current medical certificate?

The responsibility for determining a pilot’s fitness to fly ultimately lies with the pilot themselves, even when they possess a current medical certificate. While the medical certificate reflects that the pilot meets the established health criteria at the time of the exam, it does not account for any changes in the pilot's condition or health status that may occur after its issuance.

A pilot must continuously evaluate their physical and mental well-being before each flight, considering factors like fatigue, stress, or any sudden medical issues that arise. This self-assessment is crucial because, regardless of the medical certification, the pilot is the one who is intimately familiar with their current state and should make an informed decision about whether they are fit for flight.

While others, such as flight instructors or co-pilots, can provide support and advice, the final call regarding fitness to fly remains the pilot's duty. This ensures a high level of personal responsibility and safety in aviation, emphasizing the critical importance of a pilot being honest and aware of their own capabilities.
