Introduction to Master Minimum Equipment List (MMEL) and Minimum Equipment List (MEL) – 1 Day


The MEL is an operational document available for the flight crew to review in the event of any inoperative equipment being offered for the flight. Any equipment failures which potentially affect the airworthiness of the aircraft must be assessed in accordance with the MEL prior to acceptance for flight.

A minimum equipment list (MEL) is typically based on the master minimum equipment list and provides for the operation of aircraft, subject to specified conditions, with particular equipment inoperative.

The MEL is “owned” by the operator and approved by the Civil Aviation Authority CAA

Either in conformity with or more restrictive than, the MMEL established which has been established for the aircraft type. (ICAO Annex 6: Operation of Aircraft)

The master minimum equipment list (MMEL) is a list established for a particular aircraft type by the organization responsible for the type design with the approval of the State of Design

The operator shall include in the operations manual a minimum equipment list (MEL), approved by the State of the Operator which will enable the pilot-in-command to determine whether a flight may be commenced or continued from any intermediate stop should any instrument, equipment, or systems become inoperative.

The MEL is entirely separate from the Configuration Deviation List (CDL), which is a list of secondary airframe and engine components which may be recorded as missing without prejudicing the acceptance of an aircraft for flight.
