- 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…

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 7: Aircraft Systems › Oxygen Systems › Servicing of Oxygen Systems
Servicing of Oxygen Systems Before servicing any aircraft with oxygen, consult the specific aircraft service manual to determine the type of equipment required and procedures to be used. Certain precautions should be observed whenever aircraft oxygen systems ... serviced. Oxygen system servicing should be accomplished only when the aircraft is located outside of the hangars. Personal cleanliness and good housekeeping are imperative when working with oxygen. Oxygen under pressure creates spontaneous results when brought in contact with petroleum…

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…

complete fire protection system on modern aircraft, and on many older aircraft, includes a fire detection system and a fire extinguishing system. Typical zones on aircraft that have a fixed fire detection and/or fire extinguisher system are: To detect fires ... overheat conditions, detectors are placed in the various zones to be monitored. Fires are detected in reciprocating engine and small turboprop aircraft using one or more of the following: 1. Overheat detectors. 2. Rate-of-temperature-rise detectors. 3. Flame…
