17
Q

The gas generator section shaft drives the reduction gearbox. (Dash 1, 1-12)

T/F

A

False – There is no mechanical connection between the gas generator section and the RGB. Hot gases drive the RGB from the gas generator section.

18
Q

The CHIP annunciator indicates ___________. (Dash 1, 1-12)

There is metal contamination in the fuel system
There is metal contamination in the hydraulic system
There is metal contamination in the oil system
Impending engine failure

A

There is metal contamination in the oil system

19
Q

The PCL (Power Control Lever) _________. (Dash 1, 1-12/15)

Are interconnected with a push-pull rod between the cockpits
Is connected to the FMU in the front cockpit
Has a friction control adjustment in the front cockpit only
Contains speed brake, rudder trim, UHF/VHF radio, and intercommunication system switches
All of the above

A

All of the above

20
Q

The engine may be shutdown by lifting the PCL over the cutoff stop. (Dash 1, 1-15)

T/F

A

False – the fingerlift must be raised to place the PCL into the OFF position.

21
Q

When talking about the T-6A propeller, which of the following are true? (Dash 1, 1-15)

Aluminum, 97 inch
Four bladed
Constant speed, Variable pitch
Both B and C
All of the above
A

All of the above

22
Q

What device automatically controls the propeller blade angle (pitch) and propeller speed (Np)? (Dash 1, 1-15)

Power management unit (PMU)
Propeller interface unit (PIU)
Engine data manager (EDM)
Both A and B
All of the above
A

Both A and B

23
Q

When feathered, the propeller blades are aligned nearly straight into the wind, thereby minimizing drag. (Dash 1, 1-15)

T/F

A

True

24
Q

If oil pressure is lost, the propeller will automatically freeze in its present pitch position. (Dash 1, 1-15)

T/F

A

False – it will automatically move to the feathered position due to the feathering spring and counterweights.
