Which document provides the operator with the official list of approved inoperative configurations for flight?

• A. Minimum Equipment List (MEL)
• B. Flight Manual
• C. Company Operations Manual (COM)
• D. Master Minimum Equipment List (MMEL)

Answer: (A)

Understanding how aircraft can still fly with some equipment inoperative rests on a clear set of dispatch rules. The key idea is that operators need an official, legally approved list that specifies what can be left unserviceable and under what conditions a flight may still depart. This is provided by the Minimum Equipment List. The MEL is tailored to the operator’s fleet and is approved by the aviation authority, detailing which items may be inoperative, what checks are required, and what maintenance actions must be taken by certain times. It bridges the generic possibilities outlined in the master list with the operator’s actual operations, ensuring safety and regulatory compliance for each flight. The Master Minimum Equipment List is the broader, aircraft-type reference that outlines all potential inoperative configurations at a high level. It informs the creation of the operator’s MEL, but on its own it isn’t the specific, officially approved dispatch document used by a particular airline or operator. The Flight Manual contains procedures for normal and abnormal operations, not the official inoperative configurations for dispatch. The Company Operations Manual covers company procedures and may reference MEL requirements, but it does not itself govern which inoperative configurations are permitted for flight. So, the document that provides the official list of approved inoperative configurations for flight is the Minimum Equipment List.
