Which document specifies minimum equipment required for flight in the event of equipment failure?

• A. ARC
• B. Flight Plan
• C. MEL
• D. Insurance Certificate

Answer: (C)

The key idea is understanding how flight can proceed when some equipment is inoperative. The Minimum Equipment List is the document that specifies which items may be out of service and under what conditions the flight may continue. It defines the minimum set of equipment that must be operable for a given flight and the limitations, actions, and time frames required to operate with any inoperative items. This is what lets an aircraft depart even when a nonessential system is failed, as long as the failure is covered by the MEL and the flight remains within its allowed limits. The other documents have different purposes: the ARC (airworthiness certificate) confirms ongoing airworthiness but doesn’t specify inoperative equipment; a flight plan is about the planned route, altitude, speed, and timing of the flight; an insurance certificate provides proof of insurance coverage. So, the document that directly addresses minimum equipment requirements in the event of a failure is the MEL.
