- Chapter 7: Aircraft Systems › Electrical System
Electrical System Most aircraft are equipped with either a 14- or a 28-volt direct current (DC) electrical system. A basic aircraft electrical system consists of the following components: Alternator/generator Battery Master/battery switch • Alternator/generator switch • Bus bar, fuses, and circuit ... breakers • Voltage regulator • Ammeter/loadmeter • Associated electrical wiring Engine-driven alternators or generators supply electric current to the electrical system. They also maintain a sufficient electrical charge in the battery. Electrical energy stored in a battery provides a source of electrical…
- Chapter 18: Emergency Procedures › In-Flight Fire › Cabin Fire
Cabin Fire Cabin fires generally result from one of three sources: (1) careless smoking on the part of the pilot and/or passengers; (2) electrical system malfunctions; or (3) heating system malfunctions. A fire in the cabin presents the pilot with ... immediate demands: attacking the fire and getting the airplane safely on the ground as quickly as possible. A fire or smoke in the cabin should be controlled by identifying and shutting down the faulty system. In many cases, smoke…
- Chapter 7: Aircraft Systems › Heating System › Fuel Fired Heaters
Heating System There are many different types of aircraft heating systems that are available depending on the type of aircraft. Regardless of which type or the safety features that accompany them, it is always important to reference the specific aircraft ... become knowledgeable about the heating system. Each has different repair and inspection criteria that should be precisely followed. Fuel Fired Heaters A fuel fired heater is a small mounted or portable spaceheating device. The fuel is brought to the heater…
- Chapter 18: Emergency Procedures › System Malfunctions › Electrical System
System Malfunctions Electrical System The loss of electrical power can deprive the pilot of numerous critical systems, and therefore should not be taken lightly even in day/visual flight rules (VFR) conditions. Most in-flight failures of the electrical system ... located in the generator or alternator. Once the generator or alternator system goes off line, the electrical source in a typical light airplane is a battery. If a warning light or ammeter indicates the probability of an alternator or generator…

light in weight and easily adaptable to any mounting position. 9. Detector circuitry that operates directly from the aircraft power system without inverters. 10. Minimum electrical current requirements when not indicating a fire. 11. Each detector system should turn ... flight deck light, indicating the location of the fire, and have an audible alarm system. 12. A separate detector system for each engine. Engine Fire Detection Systems Several different types of fire detection systems are installed in aircraft to detect…
- Chapter 17: Fire Protection Systems › Cargo & Baggage Compartment Fire Detection & Extinguisher System › Smoke Detector System
Smoke Detector System The optical smoke detector consists of source light emitting diodes (LEDs), intensity monitor photodiodes, and scatter detector photodiodes. Inside the smoke detection chamber, air flows between a source LED and a scatter detector photodiode. Usually, only ... small amount of light from the LED gets to the scatter detector. If the air has smoke in it, the smoke particles reflect more light on the scatter detector. This causes an alarm signal. The intensity monitor photodiode makes sure…
