What does MEL stand for, and how does it influence dispatch decisions?

• A. Maximum Equipment List; lists items that must be operative
• B. Minimum Equipment List; lists items that may be inoperative under certain conditions with specified limitations; affects dispatch
• C. Mechanical Equipment List; tracks maintenance
• D. Mandatory Engineering List; not relevant

Answer: (B)

Minimum Equipment List identifies which items may be inoperative and still allow a flight to depart, but only under the specific conditions and limitations documented for each item. This directly shapes dispatch decisions because a flight can be approved to depart with certain inoperative equipment if the MEL entry for that item is satisfied—meaning the aircraft remains safe to operate under the defined limitations, such as using alternate procedures or accepting reduced capability. If a required item isn’t covered by the MEL or the conditions aren’t met, the flight must not dispatch until the item is repaired. In short, the MEL is the regulatory-approved guide that tells crews and dispatchers when and how an inoperative piece of equipment can be tolerated during a flight.
