What is the purpose of the Dry Bay Fire Suppression System?

• A. Suppression is achieved for fire events associated with ballistic damage before a significant fire occurs. Performs without pilot action.
• B. To extinguish all aircraft fires after pilots evacuate.
• C. To cool the cockpit during engine fire.
• D. To vent smoke into cabin.

Answer: (B)

The Dry Bay Fire Suppression System is designed to automatically extinguish fires that start in the dry bays, especially when damage from ballistic events could ignite fuel or other materials. It responds without requiring any action from the crew, aiming to stop a fire before it becomes significant and threatens critical systems. This system is targeted to the dry bays themselves, not the entire aircraft.

That’s why it isn’t about cooling the cockpit during an engine fire, nor about venting smoke into the cabin, and it doesn’t extinguish all fires after pilots evacuate. Its purpose is to rapidly suppress fires in the dry bays automatically to protect the aircraft’s essential systems.
