31
Q

What is the purpose of the lead stop?

A

To limit the lead spindle travel during rotor break operations.

32
Q

Is single engine operation with the gust lock engaged authorized on the H-60M that has a rotor brake installed?

A

No

33
Q

How long can the intermediate gear box run at cruise flight with loss of all oil?

A

The intermediate gear box may run at cruise flight for UP TO 30 minutes with loss of all oil.

34
Q

What are the primary components of the H-60 hydraulic system?

A

-Hydraulic Pump -Transfer Module -Primary Servos -Tail Rotor Servo

35
Q

The #1 Hydraulic System supplies hydraulic pressure to what components?

A

No. 1 System: #1 Hydraulic Pump -> #1 Transfer Module -> 1st Stage Primary Servos and 1st Stage Tail Rotor Servo.

36
Q

The #2 Hydraulic System supplies hydraulic pressure to what components?

A

No. 2 System: #2 Hydraulic Pump -> #2 Transfer Module -> 2nd Stage Primary Servos and Pilot Assist Module Servos

37
Q

The back-up hydraulic system provides hydraulic pressure to what components?

A

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.

38
Q

The cyclic control system provides what controls for the helicopter.

A

forward, rearward, and lateral

39
Q

The tail rotor (directional) control system determines the helicopter’s what?

A

Yaw (Left / Right) by controlling the pitch of the tail rotor blades.

40
Q

What are the AFCS Subsystems?

A

SAS, FPS, TRIM, Stabilator control system, and Coupled FD (H-60M)

41
