Which document lists the minimum equipment necessary for flight authorization and continued airworthiness under specified conditions?

• A. Minimum Equipment List
• B. Maximum Equipment List
• C. Maintenance Equipment Ledger
• D. Mission Equipment Log

Answer: (A)

The minimum equipment list is the document that specifies the equipment that must be on the aircraft for flight authorization and continued airworthiness under specified conditions. It is the official guide used by operators to determine whether a flight can be conducted when certain items are inoperative, and it outlines the conditions under which those inoperative items may be deferred. This list is derived from the Master Minimum Equipment List and is approved by the regulatory authority, ensuring that even with some equipment not present, the aircraft remains legally and safely operable.

Why this fits best: it directly addresses the minimum set of equipment required for safe flight and ongoing airworthiness under defined conditions, which is the core purpose of the MEL.

Why the others don’t fit: a Maximum Equipment List would imply more than the minimum and isn’t used for authorizing flights with inoperative gear; a Maintenance Equipment Ledger is a record of tools and maintenance gear, not flight equipment requirements; a Mission Equipment Log tracks gear for a specific mission, not the standard minimum for airworthiness.
