Chapter 7: Aircraft Systems › Starting System
starter engages the aircraft flywheel, rotating the engine at a speed that allows the engine to start and maintain operation. Electrical power for starting is usually supplied by an onboard battery, but can also be supplied by external power through ... starter switch draw current from the main bus bar, but the starter will not operate until the starting solenoid is energized by the starter switch being turned to the “start” position. When the starter switch is released from the “start…

deflectors, may also be utilized. Preflight procedures include a visual inspection for any sign of FOD. Turbine Engine Hot/Hung Start When the EGT exceeds the safe limit of an aircraft, it experiences a “hot start.” This is caused ... much fuel entering the combustion chamber or insufficient turbine rpm. Any time an engine has a hot start, refer to the AFM/POH or an appropriate maintenance manual for inspection requirements. If the engine fails to accelerate to the proper speed…

purposes only and is not for specific models of engines. The following are the four types of engines: • Reciprocating powerplant • Turbine, propeller combination (turboprop) • Turbine engine incorporating a fan (turbofan) • Turbojet (pure jet) By plotting the performance curve for each ... means of comparison, numerical values for net thrust, aircraft speed, and drag are not included. Comparison of the four powerplants on the basis of net thrust makes certain performance capabilities evident. In the speed range shown to the left…

Chapter 10: Engine Maintenance & Operation › Engine Troubleshooting
impractical to list all the malfunctions that could occur in a reciprocating engine, so only the most common malfunctions are discussed. A thorough knowledge of the engine systems, applied with logical reasoning, solves most problems that may occur. Figure ... lists general conditions or troubles that may be encountered on reciprocating engines, such as engine fails to start. They are further divided into the probable causes contributing to such conditions. Corrective actions are indicated in the remedy column. The items…
