Which decision point guides whether a flight is dispatched when equipment is inoperative?

• A. Do not dispatch
• B. Cancel the flight
• C. Notify passengers
• D. Determine if the item is MEL-able or requires maintenance

Answer: (D)

When equipment is inoperative, the key decision point is whether that item is covered by the Minimum Equipment List (MEL) and what maintenance status applies. If the missing item is MEL-able, the flight can be dispatched with the specified limitations and procedures outlined in the MEL, after ensuring all MEL requirements are met (documentation, placards, alternate procedures, and any operational restrictions). If the item is not MEL-able, it generally cannot be dispatched until it is repaired or replaced, because the deficiency would render the aircraft not airworthy for that flight.

This is why the option focusing on MEL-eligibility versus maintenance needs is the best guide for dispatch decisions. The other ideas—dispatching regardless of MEL, canceling automatically, or simply notifying passengers—do not reflect how airworthiness is established: MEL allows dispatch with inoperative equipment under controlled limits, while non-MEL items typically require maintenance or repair before dispatch.
