  • Chapter 2: Aeronautical Decision-Making › TEAM Checklist: Choose and Implement Risk Controls › The DECIDE Model

    First, adjust the power to the maximum controllable level on both engines. Because the left engine is the only engine delivering thrust, the yaw increases to the right, which necessitates application of additional left rudder application. Figure ... DECIDE model has been recognized worldwide. Its application is illustrated in column A while automatic/naturalistic decision-making is shown in column B. The failed engine is the side that requires no rudder pressure, in this case the right engine. Second…

  • 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 13: Transition to Multiengine Airplanes › Low Altitude Engine Failure Scenarios › Checklist

    overrun available to land on. The use of wing flaps for takeoff virtually eliminates the likelihood of a single-engine climb until the flaps are retracted. There are two time-tested memory aids the pilot may find useful in dealing ... with engine-out scenarios. The first, “dead foot—dead engine” is used to assist in identifying the failed engine. Depending on the failure mode, the pilot will not be able to consistently identify the failed engine in a timely manner…

  • Chapter 7: Aircraft Systems › Reciprocating Engines

    These two engine designs can be further classified as: 1. Cylinder arrangement with respect to the crankshaft— radial, in-line, v-type, or opposed 2. Operating cycle—two or four 3. Method of cooling—liquid or air Radial engines were ... widely used during World War II and many are still in service today. With these engines, a row or rows of cylinders are arranged in a circular pattern around the crankcase. The main advantage of a radial engine…

  • Chapter 7: Aircraft Systems › Turbine Engines

    During cruise flight, the FADEC constantly monitors the engine and adjusts fuel flow and ignition timing individually in each cylinder. This precise control of the combustion process often results in decreased fuel consumption and increased horsepower. FADEC systems are considered ... essential part of the engine and propeller control and may be powered by the aircraft’s main electrical system. In many aircraft, FADEC uses power from a separate generator connected to the engine. In either case, there must…

  • Chapter 8: Engine Removal & Replacement › Reasons for Removal of Reciprocating Engines › Engine Operational Problems

    Turbine Engine Condition Monitoring Programs Many turbine engines are monitored by an engine condition program that helps determine the health of the engine in service. This can also be called trend analysis performance monitoring, but it consists mainly of monitoring ... certain engine parameters daily and watching for trend shifts or changes in the engine parameters. A shift in key parameters (change over time) could be a warning that the engine has serious internal deterioration and should be overhauled. Engine Operational…
