No
How long can the intermediate gear box run at cruise flight with loss of all oil?
The intermediate gear box may run at cruise flight for UP TO 30 minutes with loss of all oil.
What are the primary components of the H-60 hydraulic system?
-Hydraulic Pump -Transfer Module -Primary Servos -Tail Rotor Servo
The #1 Hydraulic System supplies hydraulic pressure to what components?
No. 1 System: #1 Hydraulic Pump -> #1 Transfer Module -> 1st Stage Primary Servos and 1st Stage Tail Rotor Servo.
The #2 Hydraulic System supplies hydraulic pressure to what components?
No. 2 System: #2 Hydraulic Pump -> #2 Transfer Module -> 2nd Stage Primary Servos and Pilot Assist Module Servos
The back-up hydraulic system provides hydraulic pressure to what components?
It supplies pressure through the utility module to the second stage tail rotor servo, and it recharges the APU accumulator following APU starts. It also supplies pressure to the #1 and #2 transfer modules to operate all servos normally supplied by the #1 and #2 hydraulic systems when those systems are not operational.
The cyclic control system provides what controls for the helicopter.
forward, rearward, and lateral
The tail rotor (directional) control system determines the helicopter’s what?
Yaw (Left / Right) by controlling the pitch of the tail rotor blades.

What power does the Generator output?
115/200 Voltage Alternating Current (VAC)
What does the Swash Plate do?
Transfers input from the pilots to the main rotor flight controls
What does the Main Rotor Dampeners do?
Reduces Lead and Lag Stresses on the rotors. (Gold band means good)

Reduces Vibrations
How many Pressure Reducer Indicator Button (LRB’s) are on the UH-60?
7 Total: -2 per Hydraulic Pump (3 pumps = 6) -1 Pilot Assist Module
What do Droop Stops do?
Prevent the “Drooping” of the Rotor Blades as they slow and stop
What does the Gust Lock do?
Locks the rotors in place so they cant spin when aircraft is parked. (Slides upwards from Aft cabin into the Rotor Brake Disc)
What do the pitch control rods do?
Transmit all the movement of the flight controls from the swashplate to the main rotor blades.
