- Chapter 7: Aircraft Systems › Full Authority Digital Engine Control (FADEC)
Full Authority Digital Engine Control (FADEC) FADEC is a system consisting of a digital computer and ancillary components that control an aircraft’s engine and propeller. First used in turbine-powered aircraft, and referred to as full authority ... digital electronic control, these sophisticated control systems are increasingly being used in piston powered aircraft. In a spark-ignition reciprocating engine, the FADEC uses speed, temperature, and pressure sensors to monitor the status of each cylinder. A digital…
- Chapter 2: Engine Fuel & Fuel Metering Systems › Basic Fuel System
During starting, the boost pump forces fuel through a bypass in the engine-driven pump to the metering device. Once the engine-driven pump is rotating at sufficient speed, it takes over and delivers fuel to the metering device ... specified pressure. The airframe fuel system begins with the fuel tank and ends at the engine fuel system. The engine fuel system usually includes the engine-driven pumps and the fuel metering systems. In aircraft powered with a reciprocating engine…

This stress is torsional and affects all bolts, not just the top bolts. A typical engine mount ring shown in Figure 8-16 discloses fittings and attachment points located at four positions on the engine mount structure. Each fitting houses ... dynamic engine mount. The section of an engine mount where the engine is attached is known as the engine mount ring. It is usually constructed of steel tubing having a larger diameter than the rest of the mount structure…
