Hydraulics Flashcards
The 5 systems that are hydraulically powered are
- Landing Gear
- Brakes
- Flaps
- Spoilers
- TRs
PTM 13-11
What 4 things can the Auxiliary Hydraulic system do?
- Recharge the brake accumulator
- Power the normal braking system
- Extend flaps
- Extend gear
PTM 13-11
What does an illuminated brush light on the hydraulic system service panel indicate? Is the plane airworthy?
It indicates the brushes for the electric aux hyd. pump are near service limits. The aircraft is legal to fly.
AFM 2-3
If the “ADD”, “OVER”, or “FILTER” light is illuminated on the hydraulic system service panel, is the plane airworthy?
No
AFM 2-3
Electrical power for the hydraulic system service panel can be provided by the ( ) or ( ).
Main batteries
SPPR panel switch
PTM 13-2
After starting an engine, pilots must check the ( ) to ensure proper hydraulic pressure before ( ).
corresponding hydraulic pump
starting the other engine.
PTM 13-5
Pilots experiencing a white L HYD PUMP LOW and red L FUEL PRESS LOW simultaneously, most likely have a ( ).
failure of the common shaft that drives both the motive flow pump and hydraulic pump.
PTM 5-14
The flow rate of the aux hyd. pump is ( ) than the engine driven pumps, resulting in ( ).
less
increased time to lower the landing gear and flaps.
PTM 13-5
The hydraulic cross flow valve will deactivate if the amber AUX HYD QTY LOW CAS msg illuminates, preventing ( ).
hydraulic pressure from reaching the landing gear and flaps and preserving the remaining pressure for the normal braking system.
PTM 13-9
Does the aux hyd. pump automatically turn on when the gear is selected down?
Yes, but it should be selected “ON” manually. Otherwise it will result in brake fault or failure CAS messages.
PTM 13-8
Does the aux hyd. pump automatically turn on when the gear handle is selected up?
No, it automatically turns off
PTM 13-8
The only way to charge the brake accumulator is ( ).
with the aux hyd pump.
PTM 13-7
Normal hydraulic pressure is ( ).
3000 psi
PTM 13-9
