The MEL tells us?

• A. What equipment is allowed to be inoperative on the outside of the aircraft and what procedures to follow.
• B. What equipment is allowed to be inoperative inside the aircraft and what procedures to follow.
• C. The maximum allowable fuel load and balance limits.
• D. Recommended crew rest schedules.

Answer: (B)

The Minimum Equipment List tells you which equipment inside the aircraft may be inoperative and what procedures to follow to continue operating safely. It focuses on items that are installed and accessible within the airplane and provides the conditions, limits, and required actions for dispatch with those inoperative items. This makes it the right answer because it directly addresses inoperative on-board equipment and the corresponding procedures, rather than outside-of-aircraft equipment, fuel/balance details, or crew rest rules. For example, if a certain cockpit indicator is out of service, the MEL specifies whether you can still fly, what alternate methods you must use, and any time limits or restrictions.
