17
Q

What conditions will cause the Ram Air Turbine (RAT) to automatically deploy?

A

All of the above.

Both engines are failed and center hydraulic system pressure is low.

Both AC transfer busses are unpowered.

All three hydraulic system pressures are low.

18
Q

What occurs if both center hydraulic system demand pumps are turned to the ON position?

A

Only the C1 demand pump operates.

19
Q

With the left and right hydraulic demand pump selectors in the AUTO position, when will both pumps operate?

A

All of the above.

During landing.

During takeoff.

When system or primary pump pressure is low.

20
Q

With all hydraulic pumps selected to AUTO or ON, which center pump will load shed if only a single power source is available?

A

C2 primary pump

21
Q

Which of the following is the hydraulic function of the Ram Air Turbine (RAT)?

A

Provides hydraulic power to the center hydraulic system flight controls only.

22
Q

The right hydraulic system powers flight controls, normal brakes and the right thrust reverser.

A

True

23
Q

What components are powered by the center hydraulic system?

A

Flight controls and Flap/Slats.

Alternate/reserve brakes.

Landing gear actuation and Nose/Main gear steering.

All of the above.

24
Q

Where are hydraulic system pressure and quantity indications displayed?

A

The Status and Hydraulic Synoptic pages.

25
Q

What components are powered by the left hydraulic system?

A

Flight controls and the left engine thrust reverser.

26
Q

If a leak occurs in the center hydraulic system as shown, when low quantity is sensed, what action has happened in the hydraulic center system?

A

Both isolation valves close to protect alternate brakes and nose gear actuation and steering

27
Q

While in flight after a center hydraulic system fluid loss, what condition allows the right isolation valve to re-open?

A

It will not re-open. Maintenance must re-open it after the flight.

28
Q

With the EICAS HYD QTY LOW C and this synoptic indication, which of the following are true?

A

All the above.

Pilots should anticipate possible complete loss of the center hydraulic system, and consider referring to that checklist.

The left isolation valve will reopen when the landing gear is selected down and both left and right engine driven primary hydraulic pumps are providing normal pressure.

Nose wheel steering may be slow to react.

29
Q

With this message displayed how will flap/slat operation be affected?

HYD PRESS SYS C

A

Flaps/slats will operate in the Secondary mode.

30
Q

With these messages depicted, how do the flap/slats operate?

SLATS PRIMARY FAIL
FLAPS PRIMARY FAIL

A

Electrically, using the flap handle, with flap asymmetry protection in the secondary mode.

31
Q

With the flap/slats operating in the Secondary mode, what subsequent failure would require one to use the Alternate Flap/Slat mode of operation?

A

Flap/Slat Electronic Units (FSEUs) failure/malfunction

32
Q

The landing gear doors are operated by the ____ hydraulic system.

A

Center

33
Q

A landing gear door powered by the center hydraulic system fails to close after gear retraction. This is indicated by the ____.

A

EICAS advisory message GEAR DOOR

34
Q

After the EICAS advisory message GEAR DOOR is displayed, the affected gear door can be identified by ____.

A

selecting the GEAR synoptic

35
Q

If both of these pumps are selected ON, ____________.

C1 AND C2 AIR DEMAND PUMPS

A

only C1 air driven pump operates

36
Q

In the scenario depicted by this synoptic with a dual engine failure in flight, the First Officers flight instrument go blank. Which of the following statements is correct?

A

RAT has shed electrical in order to maintain hydraulic pressure for flight controls, and main aircraft battery is powering the Standby Electrical System.

37
Q

After reviewing the synoptic, what center system components are now hydraulically powered?

A

Center Flight controls

38
Q

On approach at ORD and after landing gear extension, the crew sees this EICAS message. After placing the RIGHT DEMAND PUMP SELECTOR to ON, the caution message remains displayed. The ____ brake system will be used for braking.

HYD PRESS SYS R

A

Alternate

39
Q

With the loss of normal braking, the brake system will switch over to the alternate system ____.

A

automatically

40
Q

For consideration upon landing, when using the Alternate braking system, will anti-skid be available?

A

Yes, tandem wheel pairs except the aft axle wheels are independent
