Flight Controles & Hydraulics Flashcards
Only the cyclic and collective incorporate hydraulic servo actuators
a) True.
b) False.
A) True.
The tail rotor pedals are hydraulically boosted.
a) True.
b) False.
B) False
The synchronized elevator is linked to
a) Fore and aft movement of the cyclic.
b) Lateral movement of the cyclic.
c) Collective pitch movement.
A) Fore and aft movement of the cyclic.
The synchronized elevator allows for
a) Better handling characteristics during autorotation.
b) Level flight attitude at maximum continuous power (torque).
c) Increased C.G. range.
C) Increased C.G. range.
The hydraulic system is electrically controlled;
a) Fail safe to ON.
b) Fail safe to OFF.
c) Fail safe to RESET.
A) Fail safe to ON.
Three servo actuators are mounted on the cabin roof, forward of the transmission;
a) Two for collective inputs, and one for cyclic input.
b) One for tail rotor control, one for collective input, and one for cyclic input.
c) One for collective input, and two for cyclic inputs.
C) One for collective input, and two for cyclic inputs.
The hydraulic reservoir is mounted
a) On a brace and support forward of the transmission.
b) On a bi-pod support at the top aft portion of the main rotor transmission.
c) Under the engine oil reservoir, aft of the engine deck.
A) On a brace and support forward of the transmission.
Hydraulic oil is cooled by
a) The engine oil cooler blower.
b) A transmission mounted fan under the hydraulic reservoir.
c) No specific cooling system; heat dissipates from hoses and lines as air circulates.
C) No specific cooling system; heat dissipates from hoses and lines as air circulates.
The hydraulic pump is mounted on and driven by
a) Mounted on the aft side of the transmission and driven by a poly-V belt off the main driveshaft.
b) The transmission.
c) The engine accessory gearbox.
B) The transmission.
The hydraulic system has two filters, one in the pressure line, and one in the return line. Both have an impending clog indicator (red button).
a) True.
b) False.
A) True
Both hydraulic filters have bypass capability.
a) True.
b) False.
A) False
Only the hydraulic return line filter has bypass capability to prevent over-pressurization of the return system.
a) True.
b) False.
A) True.
