What will happen to the return line If the oil line between the scavenge pump and the oil cooler separates?. the oil will accumulate in the engine. the return oil will be pumped overboard. the cooler check valve will close and force the oil to bypass the cooler and return to the tank via the cold oil line. the scavenge return check valve will close and force the oil to bypass directly to the intake side of the pressure pump.

The capacity of the oil scavenge system must be _____________ the capacity of the pressure system. more than 1/4 and less than 1/2. more than 1/2 and less than 3/4. equal to. at least double.

On a turbine engine, a stater-generator requires a. compound motor for the starter only. shunt motor for both starter and generator. drive spline which disengages from the accessory gearbox. drtve spline whlch stays permanently engaged to the engine.

The air source supplied to an air-turbine starter is. low pressure, low volume. low pressure, high volume. high pressure, low volume. high pressure, high volume.

A carbon seal found on turbine engines. normally rides on a highly polished surface. maintains an air gap clearance. is similar in design to a labyrinth seal. will have grooves forming sealing rings In a concentric path sirmilar to a screw thread.

Temperature taken aft of the turbine wheel(s) is known as. EGT. ITT. TIT. T4.

Which of the foflowing are the most common types of thrust reversers used on turbine engine powered aircraft. cascade vane and blocker door. mechanical-blockage and aerodynamic blockage. comwergent and divergent. rotary air vane and statlonary alr vane.

Turbine engines utilize a capacitor-discharge lgnition system that has a high voltage and. reduces the p0ssIbility of a hot start. very high heat Intensity. very low amperage. very little tendency to create flashover at hlgh altitudes.

Air enters the centrifugal flow compressor impeller at the. perimeter. centre. side. rear.

Which of the following could cause flameout. wind. rain. turbulence. reverse thrust.

An engine reduction gear is designed to. reduce wear on the thrust bearing. provide a reduced RPM for the governor. provide an engine RPM lower than that of the propeller or transmission shaft. provide a propeller or transmlssion RPM lower than that of the engine.

The brake horsepower (BHP) of an engine is. the calculated theoretkal power output. the total power developed, disregarding friction losses. the total energy expended in all combustion chambers. the total power output actualy delivered.

Manifold pressure Is defined as. the atmosphere pressure when the engine is operating. the absolute pressure In the Intake manifold. the differential pressure In the Intake manifold. the pressure measured at the venturi of the carburetor.

Which of the following results in a decrease in volumetric efficlency?. Short intake pipes of large diameter. Cylinder head temperature too low. Carburetor air temperature too low. Part-throttle operation.

Piston rings are usually made of. stainless steel. gray cast iron. cast aluminum. nickel steel.

The reason why choke-type cylinders are used is to. compensate for normal cylinder barrel wear. increase the compression for starting purposes. provide a straight cylinder bore at operating temperature. reduce the possibility of piston rings sticking in the ring grooves.
