25
What are the four modules of the T-701C/D engine?
Accessory Section Hot Section Cold Section Power Turbine
26
Which components have a bypass indicator on them?
The oil filter and fuel filter.
27
What is the procedure for an emergency engine shutdown?
Power Control Levers (PCL) to off, fuel selector levers to off, fuel boost pumps off.
28
The H-60 Main Transmission system consists of how many modules?
5: 1: Main Module (Transmission) 2: #1 Input Module 3: #1 Accessory Module 4: #2 Input Module 5: #2 Accessory Module
29
Which chip detector is connected to a 30-second time delay to allow small chips and fuzz to burn off?
Main transmission.
30
When should the Oil dipstick sides be checked? (Hot & Cold)
Hot Side: Within 30 min of shutdown Cold Side : 2 hours past shutdown (Just FYI 7 gallon oil capacity)
31
What is the purpose of the lead stop?
To limit the lead spindle travel during rotor break operations.
32
Is single engine operation with the gust lock engaged authorized on the H-60M that has a rotor brake installed?
No
33
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.
34
What are the primary components of the H-60 hydraulic system?
-Hydraulic Pump -Transfer Module -Primary Servos -Tail Rotor Servo
35
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.
36
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
37
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.
38
The cyclic control system provides what controls for the helicopter.
forward, rearward, and lateral
39
The tail rotor (directional) control system determines the helicopter's what?
Yaw (Left / Right) by controlling the pitch of the tail rotor blades.
40
What are the AFCS Subsystems?
SAS, FPS, TRIM, Stabilator control system, and Coupled FD (H-60M)
41
True or False: The purpose of the HYD LEAK TEST switch is to electrically check all leak detection/isolation components?
TRUE
42

44
What is considered adequate settling time for JP fuel prior to obtaining a fuel sample?
Four Hours
45
How can the H-60 aircraft be refueled?
