In the event of a smoke or fire indication on board, what is the recommended crew response?

• A. Descend to 10,000 ft immediately.
• B. Return to the gate immediately.
• C. Ignore it.
• D. Follow abnormal/emergency procedures, isolate source if possible, and coordinate with ATC.

Answer: (D)

When smoke or fire is indicated, the priority is to act in a disciplined, procedure-driven way. The crew must follow abnormal or emergency procedures, which are designed to manage the situation safely and quickly. If it’s safe to do so, isolate the source of the smoke or fire to limit its spread and buy time. Simultaneously, communicate with air traffic control to declare an emergency, request priority handling, and coordinate a diversion to a suitable airport with firefighting services available. This structured approach preserves aircraft control, protects passengers and crew, and ensures the safest possible outcome.

Choosing a fixed altitude drop or returning to the gate without following emergency procedures can create new risks and delays, and ignoring the situation is obviously unsafe.
