Chapter 13 – Hydraulics Flashcards
- What three things will illuminate the System Fault light?
a. Low hydraulic system pressure
b. Low hydraulic reservoir quantity
c. Excessive hydraulic fluid temperature (AOM 13-1)
- What will turn on the #4 demand pump if the switch is in Auto?
a. Engine pump output pressure is low
b. #4 fuel control switch in CUTOFF
c. Flaps are in transit d. Flaps out of up in flight (AOM 13-1)
- On descent into KLAX, the #4 hydraulic quantity goes to zero. What systems will be
affected for the approach and landing?
a. Right outboard elevator
b. Outboard trailing edge flap hydraulic operation
c. Two inboard spoiler panels on each wing
d. Wing gear hydraulic extension and retraction
e. Normal brake source f. Autobrake (QRH 13-9)
- With the loss of #1 Hyd. Quant., what systems will be affected for the approach and landing?
a. Center Autopilot
b. Left outboard elevator
c. Inboard trailing edge flap hydraulic operation
d. Nose and body gear hydraulic extension and retraction
e. Nose and body gear steering
f. System 1 alternate brake source (QRH 13-8)
- With the loss of systems 2 & 3, why is there a speed additive for the approach?
a. To alleviate excessive elevator control load at landing speed. (Speed additive for inop
stab trim is applied automatically in the Aerodata solution for Two Hydraulic Systems Inoperative) (QRH 13-11)
- On landing the Brake Source light illuminates, what does this mean?
a. Active brake hydraulic sources (hydraulic systems 4, 1, and 2) have low pressure
(Basically you have no brakes)(AOM 14-6)
- The demand pumps are powered how?
a. 1 and 4 are Pneumatic b. 2 and 3 are Electric (AOM 13-5)
- The Aux Pump(s) is powered from which source?
a. Ground Handling Bus (AOM 6-13)
- With the #4 Aux pump on and providing pressure, will the HYD SYS fault light be off or on?
a. Off (AOM 13-1)
- What is the minimum hydraulic quantity for dispatch? Where do you read that value?
a. 0.80 is desired min qty. No RF on the STAT page or the Hydraulic synoptic (AOM NP-30)
