INTRODUCTION
The fire protection system is divided into two subsystems:
- Fire detection
- Fire extinguishing
The fire detection system detects fire in the engines and APU and overheat detection in the main landing gear bays.
The fire extinguishing system provides extinguishing capability for the engines and APU.
The detection and extinguishing systems are tested and monitored from the flight deck.
