FAA Aircraft Dispatcher Practice Exam

The Minimum Equipment List (MEL) is the correct manual to refer to when dealing with inoperative instruments during flight. The MEL is a critical document that outlines which instruments, equipment, or systems can be inoperative for a flight to still be considered airworthy. It provides specific guidance on how an aircraft can operate safely with certain equipment out of service, including any required limitations or operational procedures.

Understanding the MEL is vital for dispatchers and flight crews because it ensures compliance with regulatory requirements and helps maintain safety standards. If an instrument is inoperative, the MEL will indicate whether the flight can proceed, under what conditions, and any necessary restrictions or modifications to the flight plan.

The other manuals, while important, do not specifically address the protocols for inoperative instruments in flight. The Aircraft Configuration Manual details the aircraft's configuration but does not directly relate to the operational status of instruments. The Pilot's Operating Handbook contains operating limitations and procedures for flight but does not focus solely on the management of inoperative instruments. The Flight Operations Manual outlines standard operating procedures and policies but does not specify individual equipment status and its impact on flight safety. Thus, the MEL is the definitive guide for this situation.
