Indicates a magneto not grounding in OFF position ( C )is an undesirable practice, but indicates that nothing is wrong Question:00020 Group:0 Difficult:1 C18The most probable reason an engine continues to run after the ignition switch has been turned off is( A )carbon deposits glowing on the spark plugs ( B )a magneto ground wire is in contact with the engine casing ( C )a broken magneto ground wire Question:00021 Group:0 Difficult:1 C19If the ground wire between the magneto and the ignition switch becomes disconnected, the engine( A )will not operate on one magneto ( B ) cannot be started with the switch in the BOTH position ( C )could accidentally start if the propeller is moved with fuel in the cylinder Question:00022 Group:0 Difficult:1 A20A way to detect a broken magneto primary grounding lead is to ( A )idle the engine and momentarily turn the ignition off ( B )add full power, while holding the brakes, and momentarily turn off the ignition ( C )run on one magneto, lean the mixture, and look for a rise in manifold pressure Question:00023 Group:0 Difficult:1 B21For internal cooling, reciprocating aircraft engines are especially dependent on( A )a properly functioning cowl flap augmenter ( B )the circulation of lubricating oil ( C )the proper freon/compressor output ratio Question:00024 Group:0 Difficult:1 B22An abnormally high engine oil temperature indication may be caused by ( A )a defective bearing ( B )the oil level being too low ( C )operating with an excessively rich mixture Question:00025 Group:0 Difficult:1 A23Frequent inspections should be made of aircraft exhaust manifold-type heating systems to minimize the possibility of( A )exhaust gases leaking into the cockpit ( B )a power loss due to back pressure in the exhaust system ( C )a cold-running engine due to the heat withdrawn by the heater26
