MEL is the acronym for which document used in aviation to specify required equipment?

• A. Mechanical Equipment List
• B. Major Equipment List
• C. Minimum Emergency List
• D. Minimum Equipment List

Answer: (D)

Minimum Equipment List explains exactly which equipment must be operational for a flight and which items may be inoperative under approved limits. It’s the formal document used by airlines and authorities to authorize dispatch when something isn’t functioning, detailing allowable inoperative configurations and the time frame to repair. Other names don’t correspond to the standard aviation document that specifies required equipment for flight operations, so the MEL is the correct term.
