Errorless Answers 100%.
In the event of total electrical failure, the following system will be ON regardless of switch
position (fail safe on) correct answers Hydraulics
In the event of total electrical failure, the following systems will continue to operate correct
answers Engine oil pressure, transmission oil pressure, torquemeter, N1 tachometer, N2
tachometer, NR tachometer, altimeter, airspeed, VSI, inclinometer, compass, outside air temp
What does the engine compressor consist of? correct answers 6 stage axial and single-stage
centrifugal unit that both compacts and increases the velocity of incoming air
What does the engine combustion section consist of? correct answers Outer case, inner liner,
igniter plug, fuel nozzle, burner drain valve
What happens to fuel in the engine combustion section? correct answers It is sprayed into the
chamber at a precisely controlled rate. When the igniter is energized, the fuel and air mixture
ignites. Combustion is even and continuous as long as the proper fuel to air mixture is
maintained
What does the engine turbine system consist of? correct answers 2-stage gas producer engine
mechanically linked to the compressor and gas coupled to the 2-stage power turbine
What RPM will the gas producer turbine rotate at at 100% N1 speed? correct answers 50,970
What RPM will the power turbine rotate at at 100% N2 speed? correct answers 33,290
Do the tachometers rely on electricity? correct answers No, the rotor (NR) turbine (N2) and gas
producer (N1) tachometer generators are self-generating and will operate without electrical bus
power
, When can you use the rotor brake? correct answers Application is limited to ground operation
after the engine has been shut down and NR has decreased to between 38 to 30%
What RPM does the main rotor driveshaft rotate at at 100% N2/NR? correct answers 6,016
How many stages does the transmission use to reduce engine RPM to main rotor RPM? correct
answers 2
What is the RPM reduction from engine to main rotor, in RPM and by ratio? correct answers
Reduction from 6016 to 395 RPM, a 15.23:1 ratio
How do chip detectors in the transmission work? correct answers The electronic chip detectors
consist of a probe with a permanent ceramic magnet at the end. In the even that metal particles
should become free in the oil, the magnet will attract them. When sufficient metal is attracted to
complete a circuit between the pole and the ground, the TRANS CHIP light on the caution panel
will illuminate
What is the speed reduction in the tail rotor gearbox? correct answers 2.35:1.0
What is the tail rotor assembly? correct answers A delta hinge type with two interchangeable
blades and a controllable pitch angle
How many hydraulic servos are connected to the flight controls? correct answers 1 to the
collective, 2 to the cyclic
What do the cyclic controls consist of? correct answers A control stick, torque tube, yoke,
hydraulic servo actuators, control tubes, and bellcranks
How does the cyclic work? correct answers Movement of the control stick is transmitted through
linkage and hydraulic servo actuators to the swashplate, which actuates the rotating controls to
the main rotor
