Which of the following determines oil and grease specifications for lubrication of propellers?

feeling the sequence of boots heating and have an assistant observe the load meter indications

antifriction and plasticity characteristics of grease

A powerplant using a hydraulically controlled constant-speed propeller is operating within the propeller's constant-speed range at a fixed throttle setting. If the tension of the propeller governor control spring (speeder spring) is reduced by movement of the cockpit propeller control, the propeller blade angle will

increase, engine manifold pressure will increase, and engine RPM will decrease

If a blade of a particular metal propeller is shortened because of damage to the tip, the remaining blade(s) must be

reduced to conform with the shortened blade

increased to conform with the shortened blade

necessary to achieve final balancing

Grease used in aircraft propellers reduces the frictional resistance of moving parts and is easily molded into any form under pressure. This statement defines

speed to and from the pitch changing mechanism

Why is the pulley stop screw on a propeller governor adjustable?

to limit the maximum engine speed during takeoff

remain in the full LOW PITCH position

maintain the RPM, increase the blade angle, and maintain a low angle of attack

During engine operation at speeds lower than those for which the constant-speed propeller control can govern in the INCREASE RPM position, the propeller will

remain in the full LOW PITCH position

remain in the full HIGH PITCH position

remain in the full IDLE position

When engine power is increased, the constant-speed propeller tries to function so that it wil

maintain the RPM, increase the blade angle, and maintain a low angle of attack

maintain the RPM, decrease the blade angle, and maintain a low angle of attack

maintain the RPM, maintain the blade angle, and maintain a low angle of attack

During the on-speed condition of a propeller, the

centrifugal force of the governor flyweights is equal to the speeder spring force

aerodynamic force of the governor flyweights is equal to the speeder spring force

thrust force of the governor flyweights is equal to the speeder spring force

What action takes place when the cockpit control lever for a hydromatic, constant-speed propeller is actuated?

compression of the speeder spring is changed

blade angle will decrease and RPM will increase

blade angle will increase and RPM will increase

What will happen to the propeller blade angle and the engine RPM if the tension on the propeller governor control spring (speeder spring) is increased?

blade angle will decrease and RPM will increase

blade angle will increase and RPM will increase

blade angle will decrease and RPM will decrease

The Primary purpose of propeller is to

Change Engine Horse Power to thrust

create lift on fixed airfoils of an aircraft

Provide static and dynamic stability of an aircraft in flight

Which of the following is cause for rejection of wooden propeller

An oversize hub or bolthole, or elongated bolt holes

Solder missing from screw head securing metal

No protective coating of propeller

Which of the following statement concerning the installation of new fixed pitch wooden propeller is true

Inspect the bolt for tightness, after first flight and again for next 25 hours of flying

NAS close tolerance bolts should be used to install the propeller

If a separate metal hub is used, final track should be accomplished prior to installing the hub in the propeller

The thrust of rotating propeller is a result of

an area of decrease pressure immediately in front of propeller blades

an area of low pressure behind the propeller

the angle of relative wind and rotational velocity of the propeller

The blade angle of a fixed pitch propeller

Increase in proportion to the distance each section is from the hub

How does the aerodynamic twisting force affect operating propeller blades?

it tends to turn the blades to a high blade angle

it tends to turn the blades to a low blade angle

it tends to turn the blades to a aft blade angle

Which of the following best describes the blade movement of a propeller that is in the high RPM position when reversing action is begun?

low pitch directly to reverse pitch

high pitch indirectly to reverse pitch

low pitch directly to feather pitch

How can a steel propeller hub be tested for cracks?

by magnetic particle inspection
