What is the NOMINAL PRESSURE of each hydraulic system?

Answer 13

3000psi

Question 14

Where are the hydraulic accumulators and what is their minimum pressure?

Answer 14

• # 1 and #2 IN AFT EQUIPMENT BAY
• # 3 IN RIGHT WHEEL WELL
• min pressure of 1500psi

Question 15

Which hydraulic system is used to retract the landing gear?

Answer 15

3

Question 16

What is the function of the priority valve on system 3?

Answer 16

To give priority to the FLIGHT CONTROLS and INBOARD BRAKES

Question 17

What do the L&R HEAT lights indicate?

Answer 17

Sufficient heat for wing anti-ice (29c)

Question 18

What changes when the WSHLD switches are set from LOW to HIGH?

Answer 18

The windshields go HIGH; the windows remain LOW.

Question 19

What happens to the wing and cowl anti-ice during T/R operation? Why?

Answer 19

• ANTI-ICE functions are inhibited

- 14 stage bleed air gives priority to the T/R.

Question 20

What is the FAIL SAFE MODE of the ADSHCs?

Answer 20

ON

Question 21

What does ADSHC mean?

Answer 21

Air Data Sensor Heat Controler

Question 22

How does the wing anti-ice system operate in NORMAL and STANDBY mode?

Answer 22

• NORMAL mode regulates valves to maintain L.E. temp (88c)

- STANDBY mode valves fully OPEN or CLOSED the temp varies (49c-82c)

Question 23

How doe the ice detector work and what is the heating cycle?

Answer 23

• Ice accumulation changes the probe’s vibration freq

- 5 seconds of heat followed by 55 seconds of no heat

Question 24

Where are the ANTI-ICE DUCTS located?

Answer 24

Aft equipment bay; under the cabin; along the wings.

Question 25

What sensor triggers a "WING OVERHEAT" warning?

Answer 25

SUFFICIENT HEAT/OVERHEAT SENSOR (end of wing leading edge)

Question 26

14th stage bleed valves fail ________________?

Answer 26

Open

Question 27

How is a bleed air leak detected on the wings?

Answer 27

There are 38 total heat detection switches on the backside of the wing bleed ducts.

Question 28

What is the purpose of the SUPPLEMENTARY GROUND ANTI-ICE system?

Answer 28

To provide adequate anti-icing during ground operations without hearing the wing to high enough values to "bake" the anti-ice fluid to the wing. This is useful for taxiing to position to abound ground ice accumulation before taking the active.

Question 29

An engine driven generator

Question 32

Which hydraulic system does the ADG power?

Answer 32

3B only

Question 33

What does AUTO switch selection do?

Answer 33

Activates hydraulic pumps when flaps are beyond 4-8 degrees.
