power unit (GPU) of adequate output. After fuel is introduced to the combustion chamber during the start sequence, “light-off” and its associated heat rise occur very quickly. Engine temperatures may approach the maximum in a matter ... pilot should watch for any tendency of the temperatures to exceed limitations and be prepared to cut off fuel to the engine. An engine tendency to exceed maximum starting temperature limits is termed a hot start. The temperature rise…

Associated electrical wiring Engine-driven alternators or generators supply electric current to the electrical system. They also maintain a sufficient electrical charge in the battery. Electrical energy stored in a battery provides a source of electrical power for starting ... engine and a limited supply of electrical power for use in the event the alternator or generator fails. Most DC generators do not produce a sufficient amount of electrical current at low engine rpm to operate the entire electrical system…

With RIGHT or LEFT selected, only the associated magneto is activated. The system operates on both magnetos when BOTH is selected. A malfunctioning ignition system can be identified during the pretakeoff check by observing the decrease in rpm that occurs ... engine stops running when switched to one magneto or if the rpm drop exceeds the allowable limit, do not fly the aircraft until the problem is corrected. The cause could be fouled plugs, broken or shorted wires between the magneto…

watch the instruments associated with engine operation. This aids in making sure that all phases of engine operation are normal. For example, engine oil pressure should be indicated within 30 seconds after the start. Furthermore, if the oil pressure ... within 1 minute after the engine starts, the engine should be shut down. Cylinder head or coolant temperatures should be observed continually to see that they do not exceed the maximum allowable limit. A lean mixture should not be used…
