Which of the following is a designated engine fire zone?

Which of the following is a designated engine fire zone?

• A. The engine power section
• B. The avionics bay
• C. The passenger cabin
• D. The wing leading edge

Answer: (A)

Engine fire zones are the areas around the engine where fire detection and suppression systems are focused to protect the core and critical components. The engine power section is the designated engine fire zone because it encompasses the region most at risk from an engine fire and where the fire suppression means are directed. This area is protected to quickly detect and suppress any fire arising from the engine itself. The avionics bay and passenger cabin are separate fire zones for electrical and occupied areas, and the wing leading edge is not the engine’s fire zone.
