- Chapter 7: Aircraft Systems › Carburetor Air Temperature Gauge › Fuel Injection Systems
Most aircraft are also equipped with an outside air temperature (OAT) gauge calibrated in both degrees Figure 7-13. Fuel injection system. Celsius and Fahrenheit. It provides the outside or ambient air temperature for calculating true airspeed and is useful ... detecting potential icing conditions. Fuel Injection Systems In a fuel injection system, the fuel is injected directly into the cylinders, or just ahead of the intake valve. The air intake for the fuel injection system is similar to that used…
- Chapter 7: Aircraft Systems › Fuel Systems › Fuel Strainers, Sumps, and Drains
Fuel placards show any limitations on fuel tank usage, such as “level flight only” and/or “both” for landings and takeoffs. Regardless of the type of fuel selector in use, fuel consumption should be monitored closely to ensure that a tank ... does not run completely out of fuel. Running a fuel tank dry does not only cause the engine to stop, but running for prolonged periods on one tank causes an unbalanced fuel load between tanks. Running a tank completely…
- Chapter 7: Aircraft Systems › Oil Systems
Oil 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…
- Chapter 4: Helicopter Components, Sections, and Systems › Centrifugal Clutch › Fuel Supply System
Fuel Supply System The supply system consists of a fuel tank or tanks, fuel quantity gauges, a shut-off valve, fuel filter, a fuel line to the engine, and possibly a primer and fuel pumps. [Figure 4-22] The fuel ... tanks are usually mounted to the airframe as close as possible to the CG. This way, as fuel is burned off, there is a negligible effect on the CG. A drain valve located on the bottom of the fuel tank…
- Chapter 10: Inspection Concepts & Techniques › Special Inspections
annual or 100-hour inspection shall inspect (where applicable) components of the engine and nacelle group as follows: (1) Engine section—for visual evidence of excessive oil, fuel, or hydraulic leaks, and sources of such leaks. (2) Studs and nuts…

check, oil and fuel pressure, and cylinder head and oil temperatures. After the engine run, check it for fuel, oil, and hydraulic leaks. Following the checklist, the entire aircraft shall be opened by removing all necessary inspection plates, access doors ... owner. A typical inspection following a checklist, on a small single-engine airplane may include in part, as applicable: • The fuselage for damage, corrosion, and attachment of fittings, antennas, and lights; for “smoking rivets” especially in the landing gear area…
