What does "MEL" stand for in aviation regulations?

In aviation regulations, "MEL" stands for Minimum Equipment List. This document is crucial for ensuring safety and compliance, as it outlines the minimum equipment that must be operational for an aircraft to be considered airworthy under specific circumstances. The MEL allows pilots and operators to manage equipment malfunctions effectively, enabling them to determine which inoperative equipment can be safely deferred for flight while ensuring that the aircraft remains safe and leagally compliant for operation.

The MEL is an essential part of an operator's flight operations and maintenance planning, as it helps minimize disruptions while also ensuring that regulatory standards are met. It is tailored to each specific aircraft type and reflects the necessary equipment required for safe operation based on the type of flight and operational environment. This structured and safety-centric approach underpins the importance of the MEL in aviation practices.
