Aircraft fire detection systems

Fire extinguishing and detection systems in general. A fire detection card in the system card file monitors the loops for fires, overheat conditions, and faults. Their location, together with their small size, increases the chance of damage to the sensing elements during maintenance. A simple and short video explaining the aircraft engine fire protection system. Engines turbines apu auxiliary power unit this is a small engine installed generally in the aircraft tail. New firesmoke detection and fire extinguishing systems for aircraft. As always, the greater the knowledge and understanding that crew members have of their aircraft systems, the better their ability to make well informed decisions. The project focuses on two aspects of aircraft fire protection. Aircraft fire detection system should signal the presence of a fire. If the temperature rises above a set value, indicate a fire or overheat condition.

Although the greatest percentage of the negative statis tics toward detection systems were associated. Fire protection systems faa questions a16 flashcards. Boeing 777 aircraft fire detection and extinguishing system. Continuousloop detector, or sensing system, permits more complete coverage of a fire hazard area. Three detector system types use in aircraft are the thermal switch, thermocouple, and the continuous loop. The information is included only for familiarization purposes. Thermocouple fire warning system operating principle.

Engine fire detection systems and fire zones aircraft engine fire. Thermocouple fire warning system operates on an entirely different. Typical zones on aircraft that have a fixed fire detection andor fire extinguisher system are. In some aircraft, in addition to fire and overheat detection, the kidde continuous loop system can supply nacelle temperature data to the airplane condition. Introduction the aircraft fire protection system consists of the. You will find these systems in and near the engine compartment and in the fuselage to protect the occupants. These systems monitor the conditions which could lead to a fire and are comprised of smoke detectors, heat sensors near engines or.

A detection system is also provided for the main landing gear wheel wells. Wiring system of thermocouple units divide into detector circuit, alarm circuit and. Fire detection system the aircraft systems that have fire detection are. Continuous loop systems are typically installed on transport type aircraft and provide more complete fire detection coverage by using several loop type of sensors. Engine fire detection systems part one flight mechanic. Apu auxiliary power unit this is a small engine installed generally in the. You will find these systems in and near the engine compartment. The new fire protection system is highly reliable, has a modular design and versatility to be adapted for a wide range of aircraft types. New physical and chemical ways of detecting fire at an early. The fire protection system provides detection and extinguishing of a fire in the engine. Fire detectionoverheat systems aircraft fire protection.

Fire extinguishing and detection systems in general aviation. The following section discusses the fire detection and extinguishing system of the b777 aircraft. Fire detection system protects the aircraft and passengers both in case of actual fire during flight. Engine fire detection systems and fire zones aircraft. Automatic systems can detect aircraft fires or potential ignition which might not be apparent to the crew until they have developed to an extent. Several different types of fire detection system are installed in aircraft to detect engine fires. Reactivation of a heatsensing fire detection system following the use of an extinguishing system indicates that the risk of fire remains high. Two common types used are spot detectors and continuously loop. In the modern and general aviation the fire suppression systems is divided into two subsystems the fire detection system and the fire extinguish system. Spot detector systems use individual sensors to monitor a fire zone. Two common types used are spot detectors and continuously loop systems.
