(67) Minimum Equipment Lists: Keeping Planes Flying With Inoperative Parts - YouTube

Airplanes are, by design, highly redundant. For almost every piece of equipment, there is duplicate equipment with the same function which has the capability to take over the role of its failed counterpart. Some equipment is even triple redundant! Because of this, airplanes can remain perfectly airworthy with certain equipment inoperative. When an item is set as inoperative, pilots and engineers call the item “deferred.” However, there is a set procedure to fly with inoperative items. It requires consultation with an operational document called the Minimum equipment list (MEL). Deferring aircraft equipment can only be done on the ground as it might require maintenance action from the engineering side to get the item deferred in the first place.
