How does the FOM define “minimum equipment list” (MEL)?

The definition of “minimum equipment list” (MEL) in the Flight Operations Manual (FOM) is indeed a list of instruments and equipment that must be operational for the flight. This is crucial for ensuring safety and compliance with regulatory standards. The MEL outlines specific items that are essential for the aircraft to operate safely. If any equipment or instrument on this list is not functional, it can affect the aircraft's airworthiness and the crew's ability to conduct a safe flight.

This definition highlights the importance of operational integrity and safety compliance, as pilots and maintenance crews rely on the MEL to determine whether a flight can proceed under specific conditions. The MEL is a regulatory document that ensures that all necessary systems are functioning before departure, thereby safeguarding both passengers and crew.
