What is the purpose of an MEL in aviation?

The purpose of a Minimum Equipment List (MEL) in aviation is to provide a comprehensive list of equipment that must be operational for the aircraft to be deemed safe for flight. It outlines specific items or systems that can be inoperative while still allowing the aircraft to operate legally and safely under certain conditions. The MEL enables pilots and operators to understand what equipment must be functional for the aircraft to be dispatched and helps ensure compliance with safety regulations. By specifying which equipment can be inoperative and under what circumstances, it allows for flexibility in operations while maintaining the overall safety of the flight.
