What does the term "MEL" stand for in aircraft operations?

The term "MEL" stands for Minimum Equipment List. This is a crucial document in aircraft operations, particularly for pilots and maintenance personnel. The MEL is created by the aircraft manufacturer and is approved by aviation regulatory authorities. It specifies the equipment and instruments that must be operational for the aircraft to be considered airworthy. If an item is not operational and is listed in the MEL, the aircraft can still be flown provided that certain conditions are met, which may include additional limitations or operational procedures.

The significance of the MEL lies in its role in ensuring safety and operational efficiency. It allows operators to manage minor mechanical issues without grounding the aircraft, thus improving scheduling and reducing costs. Each MEL is tailored to specific aircraft models, taking into account the importance of various systems and their impact on safety. Understanding the MEL is essential for pilots, as it helps them make informed decisions regarding the aircraft's airworthiness prior to departure.
