MEL stands for which list used in flight operations?

• A. Minimum Equipment List
• B. Maintenance Equipment List
• C. Minimum Equipment List
• D. Mandatory Equipment List

Answer: (C)

Minimum Equipment List is the document used to authorize a flight when certain equipment is inoperative, as long as the item is approved for deferment with specific limits and procedures. It’s derived from the Master Minimum Equipment List and tailored to a particular aircraft and operator, laying out which items can be inoperative, the conditions under which the flight may operate, and the time limits for repair. The MEL helps ensure safety by defining necessary substitutions, alternate procedures, placarding requirements, and maintenance actions that must occur within set time frames. The other terms aren’t used for this purpose in flight operations; the MEL specifically refers to the minimum equipment needed to dispatch an aircraft safely, even with some items not functioning.
