Study Notes
Aircraft Fire Protection Systems Overview
- Detects overheat or fire conditions in the BR725 powerplant nacelle, adjacent pylon, and APU enclosure.
- Uses fire extinguishing agent Halon 1301, with crew-activated discharge for engine nacelles and APU compartment in response to warnings.
Detection Mechanisms
- Each engine is equipped with dual-loop fire detectors in critical areas sensitive to heat.
- Engine hot bleed air ducting monitored for leaks using thermal switches that activate at set temperature thresholds.
- APU monitored by a single element sensor for fire-related overheat conditions.
Warning Systems
- Excess temperatures trigger visual and aural warnings in the cockpit for crew response.
- Two redundant continuous-loop detector elements in fire detection rails; capable of detecting temperatures exceeding 100°C above the standard operating level of 125°C.
Power Supply and Testing
- Fire and overheat detection system powered through essential DC buses, ensuring operation during APU/engine starts.
- Main battery allows system integrity testing prior to APU and engine operation and ensures functionality during AC power system failures.
Cockpit Controls
- Fire test and detection functions are accessible via the Cockpit Overhead Panel.
- APU access facilitated through fireproof access doors and panels.
Types of Detection Devices
- Fire detection systems utilize spot detectors and area detectors for smoke, fire, and overheat condition detection throughout the aircraft.
- Primary objective is to alert the crew to hazardous conditions for safety and corrective action.
