tivated with the HYD XFLOW selected
on, can provide power to the:
A. Landing gear, flaps, spoilers, brakes
and thrust reversers.
B. Emergency gear extension, brakes and
thrust reversers.
C. Ailerons, landing gear and brakes.
D. Landing gear and flaps.
2.
Hydraulic fluid from the reservoir is shut
off to the engine driven pump:
A. If the corresponding FIRE T-Handle
is pulled.
B. If the HYD XFLOW valve is opened.
C. If the FWSOV circuit breaker pops
out.
D. If the corresponding engine “FIRE
PUSH” button is depressed.
3.
The auxiliary hydraulic system operates
whenever:
A. The landing gear is transitioned UP.
B. The AUX HYD pushbutton on the
gear/hydraulic control panel is de-
pressed.
C. The ground service valve on the GSP
is positioned to GND and a hydraulic
powercart is connected to the airplane.
D. All of the above.
4.
The landing gear control valve module
provides main or auxiliary hydraulic sys-
tem pressure to power the:
A. Thrust reversers and landing gear.
B. Thrust reversers and flaps.
C. Landing gear, gear doors and flaps.
D. Landing gear, flaps and thrust re-
versers.
5.

below 2200 psi.
7.
What are the indications of low brake ac-
cumulator hydraulic pressure?

out and analog pointer on the HYD
system schematic is amber (pressure
< 1200 psi).
D. All of the above.
8.
When does the auxiliary hydraulic pump
automatically turn off?
