ch. 7 propellers FAA (24-43 questions)

What normally prevents a constant speed feathering propeller from going into feather when the engine is shut down on the ground?

Latching mechanisms

The proper operation of an electric deicing system and its timers may be monitored onboard with the use of a(n):

amp meter

Propeller fluid anti-icing systems generally use which of the following?

Isopropyl Alcohol

Propeller deicer boots are:

energized for short periods by a cycling timer

What is the function of the automatic propeller synchronizing system on multiengine aircraft?

To control engine RPM and reduce vibration

How can a steel propeller hub be tested for cracks?

By magnetic particle inspection

If a delamination is suspected on a composite propeller blade, the extent of damage:

can be confirmed by ultrasonic inspection

If an apparent propeller vibration occurs only at cruise RPM ranges, the problem is most likely caused by:

incorrect propeller for the engine

Propeller blade tracking is the process of determining:

the positions of the tips of the propeller blades relative to each other

Which of the following functions requires the use of a propeller blade station?

Measuring Blade Angle

Propeller aerodynamic (thrust) imbalance can be largely eliminated by:

correct blade contouring and angle setting

An out of balance propeller is typically corrected by:

adding weight on the light side

When lubricating a Hartzell® propeller blade with grease, to prevent damage to the blade seals, the service manual may recommend on some models to:

remove one of the two zerk fittings for the blade and grease the blade through the remaining fitting

When charging a propeller air dome to the manufacturer's specifications, which factor must be considered when determining the proper air pressure?

Temperature

Cold straightening of a bent aluminum propeller blade:

requires specialized tooling and precision measuring equipment

How is a propeller controlled in a large aircraft with a turboprop installation?

By the engine power lever

On a typical turboprop engine such as a Pratt & Whitney PT-6, oil for the governor is supplied by:

the engine oil supply

In what way do hydromatic propeller systems differ from other constant speed propeller systems?

The hydromatic system does not include counterweights

How does the propeller overspeed governor on a turboprop engine decrease propeller RPM?

As oil pressure increases, the servo piston is pushed forward, and the feather spring is compressed
