A Minimum Equipment List (MEL) is a precise listing of instruments and procedures that allows an aircraft to operate under specific conditions with inoperative equipment. It is mandated by aviation authorities and is tailored to a specific aircraft, detailing which components can be inoperative while still allowing for safe operation. The MEL ensures that the aircraft can still be flown without compromising safety, as it includes conditions and limitations for operation, such as requiring alternative procedures or additional resources when certain items are not functioning.

In contrast, the other options do not accurately reflect the role and purpose of an MEL. While a list of all equipment on board an aircraft provides inventory information, it does not address operational capabilities with inoperative equipment. A general maintenance checklist focuses on upkeep and service readiness rather than operational limitations. Finally, a guideline for passenger safety information pertains to pre-flight briefings and safety protocols, which again is distinct from the function of an MEL.
