In MEL deferral, which option describes the deferment term?

• A. Time Interval
• B. 3 Calendar Days
• C. 10 Calendar Days
• D. 120 Calendar Days

Answer: (A)

In MEL deferral, the period you’re allowed to operate with an inoperative item is described as a Time Interval. This term means there’s a defined window, specific to that MEL item, during which the aircraft may operate before the item must be repaired or addressed. The exact duration is stated on the MEL for that item and can be based on hours, cycles, or another measure, rather than a fixed calendar date. The other options—specific calendar-day durations—only apply if the MEL explicitly sets a calendar-day limit; the general deferment term used is Time Interval.
