The RGB is a two-stage planetary reduction drive to reduce the power turbine output shaft speed of over _______ RPM to the propeller operating speed of _____ RPM.
Placing the PCL to OFF triggers a microswitch activating the feather dump solenoid valve that _____________.
dumps oil pressure allowing the feathering spring and counterweights to feather the propeller
When feathered, the propeller blades are ___________.
aligned nearly straight into the wind
If PMU function is lost or deactivated, the mechanical flyweight overspeed governor modulates oil pressure to the propeller pitch change piston to maintain Np at or below _____.
With the PMU functioning, the mechanical overspeed governor modulates oil pressure to the propeller pitch change piston to limit Np below ____.
Non-engine related functions performed by the EDM include _________.
fuel balancing and quantity indication
determination and display of cockpit pressure altitude and differential pressure
determination and display of DC volts and DC amps
determination and display of hydraulic pressure and NACWS
The power management unit (PMU) is normally powered by the ______.
permanent magnet alternator (PMA)
T or F: The PMU also provides engine protection for airstart capability. During an airstart, automatic N1, ITT and torque limit protection is available; however the pilot should still monitor all parameters and abort the start manually if necessary.
Illumination of both the PMU FAIL and PMU STATUS annunciators indicates what condition?
Faults prevent the PMU from setting the requested power or respecting engine limits
PMU has been switched OFF
PMU system is in the manual mode
In relation to the Fire Warning System, power for FIRE 2 is provided through a circuit breaker, placarded FIRE 2, located on ___________.
Illumination of the PMU STATUS annunciator one minute after landing (weight-on-wheels activation) indicates what?
Fault conditions that are not serious enough to revert the system to manual were encountered in flight
Illumination of the PMU STATUS annunciator in flight indicates all but which of the following?
Fault conditions exist that are not serious enough to revert the system to manual
The fuel system provides approximately _____ of usable fuel through the single point refueling system.
Which of the following is NOT a result of pulling the emergency firewall shutoff handle?
The engine compartment extinguisher bottle is armed
If gravity (over the wing) refueling is accomplished, fuel quantity increases by ____ pounds (approximately ____ gallons).
T or F: With FP FAIL annunciation, the low fuel warning lights will no longer provide an accurate indication of minimum fuel level.
The electric boost pump:
provides fuel for engine start
serves as a backup to the engine-driven low pressure fuel pump
If the red GEN annunciator illuminates, what equipment is automatically shed?
If the FUEL PX annunciator illuminates and the boost pump activates during inverted flight, _______.
cease inverted maneuvers and notify maintenance after flight
The inverted fuel pickup system provides a minimum _____ supply of fuel regardless of orientation.
If the generator has failed and the BUS TIE switch is in the NORM position, then the battery will power:
all items except the air conditioner
If the generator bus has failed (red GEN BUS annunciator illuminated) and the BUS TIE switch is in the NORM position, _______.
The items on the generator bus will not be powered
The generator will continue to power the battery bus and charge the battery
What do the red bands on the brake reservoir filler plug indicate?
The system requires servicing (top) or is overserviced (lower)
If the generator fails while the BUS TIE annunciator is illuminated, expect a minimum of ___ of battery power to the battery bus items.
The hydraulic pump pressurizes the normal system and emergency accumulator to ______ psi.
3000 ± 120
Once hydraulic pressure exceeds ____ psi, the system can power the landing gear, main gear doors, flaps, speed brake, and nose wheel steering.
The T-6 hydraulic system powers which of the following systems?
landing gear and main gear doors
T or F: If the hydraulic fluid level is not FULL AC or FULL AD, then depressurize the emergency accumulator by pulling the manual pressure release handle until the fluid level indicates FULL AD.
What does an amber EHYD PX LO annunciator signify?
