  Chapter 7: Aircraft Systems › Heating System › Exhaust Heating Systems

  Exhaust Heating Systems Exhaust heating systems are the simplest type of aircraft heating system and are used on most light aircraft. Exhaust heating systems are used to route exhaust gases away from the engine and fuselage while reducing engine noise ... exhaust systems also serve as a heat source for the cabin and carburetor. The risks of operating an aircraft with a defective exhaust heating system include carbon monoxide poisoning, a decrease in engine performance, and an increased potential for fire…

  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…

  Chapter 7: Aircraft Systems › Oil Systems

  Systems The engine oil system performs several important functions: • Lubrication of the engine’s moving parts • Cooling of the engine by reducing friction • Removing heat from the cylinders • Providing a seal between the cylinder walls and pistons • Carrying away contaminants ... Figure 7-17. Wet-sump oil system. Reciprocating engines use either a wet-sump or a dry-sump oil system. In a wet-sump system, the oil is located in a sump that is an integral part of the engine…

  Chapter 7: Aircraft Systems › Electrical System

  Some have a warning light that, when lighted, indicates a discharge in the system as a generator/alternator malfunction. Refer to the AFM/POH for appropriate action to be taken. Another electrical monitoring indicator is a loadmeter. This type of gauge ... loadmeter reflects the total percentage of the load placed on the generating capacity of the electrical system by the electrical accessories and battery. When all electrical components are turned off, it reflects only the amount of charging current demanded…

  Chapter 7: Aircraft Systems › Fuel Systems › Gravity-Feed System

  Gravity-Feed System The gravity-feed system utilizes the force of gravity to transfer the fuel from the tanks to the engine. For example, on high-wing airplanes, the fuel tanks are installed in the wings. This places the fuel ... tanks above the carburetor, and the fuel is gravity fed through the system and into the carburetor. If the design of the aircraft is such that gravity cannot be used to transfer fuel, fuel pumps are installed. For example…

  Chapter 16: Cabin Environmental Control Systems › Vapor Cycle Air Conditioning › System Servicing

  Water is removed from the system by evacuation. Anytime the system refrigerant charge falls below atmospheric pressure, the refrigerant is lost, or the system is opened, it must be evacuated before recharging. Evacuating a vapor cycle air conditioning system ... also known as pumping down the system. A vacuum pump is connected and pressure inside the system is reduced to vaporize any water that may exist. Continued operation of the vacuum pump draws the water vapor from the system…
