Hydraulics

Question 1

Landing Gear, Flaps, Spoiler/Spoilerons, Thrust Reversers and Brakes are the five systems powered
by the (                  ) system.

Answer 1

Hydraulic. PTM Pg. 13-11

Question 2

The ( ) System can extend the landing gear and flaps, power the normal braking system and recharge the brake accumulator.

Answer 2

Auxiliary Hydraulic. PTM Pg. 13-11

Question 3

During aircraft preflight, an illuminated ( ) light on the Hydraulic System Service Panel indicates the brushes for the electric auxiliary hydraulic pump are nearing service limits, but the aircraft remains flyable.

Answer 3

Brush. AFM Pg. 2-3

Question 4

During aircraft preflight of the Hydraulic System Service Panel, if the “ADD” light, “OVER” light,
or either “FILTER” light is illuminated, the aircraft is ( ) flyable.

Answer 4

Not. AFM Pg. 2-3.

Question 5

Electrical power for the Hydraulic System Service Panel can be provided from the ( ) batteries or from the SPPR fuel panel power switch.

Answer 5

Aircraft main ship batteries. PTM Pg. 13-2

Question 6

After starting an aircraft engine, pilots must check the corresponding hydraulic pump to ensure proper hydraulic pressure before ( ) aircraft engine.

Answer 6

Before starting the other aircraft engine. PTM Pg. 13-5

Question 7

Pilots experiencing a loss of a hydraulic pump (white CAS L HYD PUMP LOW) simultaneously with the loss of the same side fuel pressure (red CAS L FUEL PRESS LOW) most likely have a failure of the ( ) shaft that drives both the motive flow pump and hydraulic pump.

Answer 7

Common shaft. PTM Pg. 5-14

Question 8

The flow rate of the Auxiliary Hydraulic pump is less than the engine driven pumps, resulting in ( ) to lower the landing gear and wing flaps.

Answer 8

Increased time. PTM Pg.13-5

Question 9

The hydraulic ( ) valve will deactivate if the amber AUX HYD QTY LO CAS message illuminates preventing auxiliary hydraulic pressure from reaching the landing gear system or flaps.

Answer 9

Crossflow valve. PTM Pg. 13-9

Question 10

Should the amber ( ) message illuminate, the hydraulic crossflow valve
will automatically deactivate to conserve the remaining auxiliary hydraulic fluid for the normal braking system.

Answer 10

AUX HYD QTY LOW CAS. PTM Pg. 13-9

Question 11

Should the amber ( ) message illuminate, the hydraulic crossflow valve
will automatically deactivate to conserve the remaining auxiliary hydraulic fluid for the normal braking system.

Answer 11

AUX HYD QTY LOW CAS. PTM Pg. 13-9

Question 12

The auxiliary hydraulic pump automatically comes on when the gear handle is extended; however, it
should be turned “ ” prior to extending the landing gear handle.

Answer 12

ON. PTM Pg. 13-8 and AFM Pg. 2-21

Question 13

The auxiliary hydraulic pump automatically turns “ ” when the gear handle is selected “UP”.

Answer 13

Off. PTM Pg. 13-8

Question 14

The only way to charge the brake accumulator is with the ( ) pump.

Answer 14

Auxiliary hydraulic. PTM Pg. 13-7

Question 15

Normal hydraulic pressure is approximately ( PSI).

Answer 15

3,000 psi. PTM Pg. 13-9
