Question:
1. Each hydraulic pump is a pressure, They maintain the required over any rate of control movement
for their own system.
Answer:
constant, variable, 3000 volume pump. PSI
Question:
2. What does the #1 hyd pump supply pressure to?
Answer:
The #1(first stage) fore, aft, and lateral primary servos and the #1 tail rotor servo
Question:
3. What does the #2 hyd pump supply pressure to?
Answer:
The #2 (second stage) fore, aft, and lateral primary servos and components of the pilot assist area
Question:
4. What does the pressure reducer in the pilot assist module do?
Answer:
Reduces the 3000 PSI pump pressure to 1000 PSI for use by the pitch trim servo
Question:
5. Besides supplying pressure to the #1 and/or #2 systems, what does the back- mulator up pump
pressurize?
Answer:
The 2nd stage tail rotor servo and the APU accu-
Question:
6. When does RSVR low come on?
Answer:
60% or less fluid remaining
,Question:
7. When will the backup pump be on?
Answer:
It supplies hydraulic pressure to flight control components during ground checks (main rotors not
turning), or the following conditions:
#1 Reservoir Low (caution light) #2 Hydraulic Pump (caution light) #1 Hydraulic Pump (caution
light) APU Accumulator Low (advisory light) #1 Tail Rotor Servo (caution light)
Question:
8.
When will the hyd pump filter button pop? When will the return bypass?
Answer:
70 psid, 100 psid
Question:
9. An entry should be made on 2408-13-1 if the TEMPE labels show an exceedance of C or should not
be flown until maintenance action has been taken.
Answer:
132, 270 F, and the A/C
Question:
10. Functions of the MMU:
Answer:
Collective to Pitch - compensates for downwash on aft fuselage and stab. Collective increase = slight
forward disk Collective to Roll - compensates for translating tendency. Collective increase = slight left
disk Collective to Yaw - compensates for torque effect of M/R. Collective increase = T/R pitch
increase Yaw to Pitch - compensates for T/R lift. Left pedal (pitch increase) = slight aft disk
Question:
11. Electronic Coupling (Collective to Airspeed to Yaw) helps compensate for the caused by changes
in collective position. It has the ability to T/R pitch as airspeed increases.
Answer:
torque effect; decrease
Question:
12. At what airspeed does maximum mixing of Electronic Coupling occur? When does it no longer
occur?
Answer:
0-40 KIAS; >100 KIAS
, Question:
5. sub systems of AFCS
Answer:
Question:
13. 5 sub systems of AFCS
Answer:
1. SAS
2. TRIM
3. FPS
4. Stabilator
5. Coupled flight director
Question:
14. Describe FPS
Answer:
Basic Autopilot- Long term rate dampening. When coupled with Trim, FPS has 100% control
authority.
Question:
15. What does FPS provide below 50 KIAS PITCH=ATT hold
Answer:
ROLL=ATT hold YAW= Hdg hold
Question:
16. What does FPS provide above 50 KIAS PITCH= ATT hold/Airspeed
Answer:
ROLL=ATT hold YAW= HDG hold/Turn coord
Question:
17. These systems must be on and operational for FPS to function at 100%
Answer:
1. SAS 1&2
2. SAS/BOOST
3.Trim
4. Stabilator (helps but not required)
