What does a Minimum Equipment List (MEL) permit regarding inoperative equipment?

• A. Flight with any inoperative equipment
• B. Flight with inoperative equipment only if the operator chooses to cancel the flight
• C. Flight with certain inoperative equipment as specified in the MEL
• D. Flight with no inoperative equipment allowed

Answer: (C)

The main idea here is that a MEL defines what inoperative equipment can be tolerated for a flight, and only under the conditions listed there. A MEL is not a free pass to fly with anything broken; it specifies which items may be deferred, along with any limitations, required procedures, placards, maintenance actions, and time limits. So the best choice is the one that says you may fly with certain inoperative equipment as specified in the MEL. This reflects how the MEL works: it grants permission to operate with specific items out of service, provided you follow the approved conditions and remedies. Items not listed, or problems outside the MEL’s scope, would not be allowed for dispatch. The other ideas don’t fit because flying with any inoperative equipment is not permitted in general, and dispatching only if you cancel the flight defeats the purpose of having an MEL. The notion of no inoperative equipment allowed ignores the MEL’s explicit allowances for certain items.
