What should a pilot do if their medical expires?

When a pilot's medical certificate expires, the correct action to take is to ground the aircraft until a new medical certificate is obtained. This is vital because the medical certificate is a legal requirement for a pilot to be considered fit to operate an aircraft. Operating an aircraft without a valid medical certificate can lead to serious legal implications and jeopardize safety, as the medical certificate ensures that the pilot meets the necessary health standards to ensure not only their safety but also the safety of passengers and others.

Grounding the aircraft also reflects a responsible decision-making process, emphasizing the importance of compliance with aviation regulations. Pilots must be aware of the certification's validity and ensure it is current before planning any flight. This approach prioritizes accountability and safety in aviation practices.
