Definition#
The Minimum Equipment List (MEL) is an authority-approved document derived from the Master Minimum Equipment List (MMEL) that lists specific instruments and equipment that may be inoperative while maintaining an acceptable level of safety. It specifies conditions, limitations, and rectification intervals.
Why It Matters Operationally#
The MEL allows dispatch with certain items inoperative, preventing unnecessary cancellations. Without an MEL, any unserviceability would ground the aircraft until repaired, significantly impacting dispatch reliability.
