What does “MEL” stand for in aviation?

In aviation, "MEL" stands for Minimum Equipment List. The MEL is a crucial document that provides pilots and operators with guidance on which equipment may be inoperative while still allowing for safe flight operations. It outlines the specific equipment and systems that can be non-functional and the conditions under which the aircraft can remain airworthy. This allows for flexibility in operations while ensuring safety standards are maintained.

Understanding the MEL is particularly important for maintaining compliance with regulations and for planning maintenance tasks without compromising the safety and performance of the aircraft. It is systematic and specific, providing a clear framework for operational decision-making concerning inoperative equipment, which is essential for flight crews when preparing for a flight.
