A

130 knots

17
Q

Which of the following will shut off the flow of hydraulic fluid to the LEFT engine pump?

A

Pull the LEFT engine fire switch

18
Q

When does the Ram Air Turbine deploy automatically?

A

Inflight when both engines fail

19
Q

Which one of the following indicates the Ram Air Turbine is producing hydraulic power?

A

RAT pressure light illuminated

20
Q

Which of the following indicates a hydraulic pump overheat?

A

An illuminated pump overheat light

21
Q

What systems are supplied hydraulic pressure by the Ram Air Turbine (RAT)?

A

Flight controls

22
Q

Which condition requires use of the Reserve Brakes and Steering switch?

A

Loss of CENTRE hydraulic system

23
Q

What is the effect on the CENTRE hydraulic system when the RAT is deployed?

A

Only primary flight controls remain powered

24
Q

What powers the RIGHT and LEFT hydraulic systems?

A

Engine driven primary pump and demand electric motor driven pump

25
Q

What system can be pressurized by the RAT pump?

A

Centre

26
Q

You have arrived at airplane for the first flight of the day. Electrical power is connected. Engines not started. In this situation, what would you do to ensure adequate brake pressure

A

Turn on the R ELEC pump switch

27
Q

In what position should the LEFT and RIGHT hydraulic system demand pumps be set for normal flight operations?

A

AUTO

28
Q

Which systems are backed up by the fluid below the stand pipe in the CENTRE hydraulic system?

A

Reserve brakes and Steering

29
Q

Centre hydraulic system provide power (if both Main AC buses are lost) to the Hydraulic Driven Generator (HDG).

A

True

30
Q

N°2 electric pump is inhibited with:

A

Only 1 generator operating, Both CENTRE electric pump switches ON, LEFT and RIGHT demand pumps operating

31
Q

The Air pump is overheating.

A

C HYD DEM PUMP OVHT light illuminates, EICAS C HYD DEM OVHT advisory message appears, corresponding reservoir temperature on EICAS increases abnormally (EICAS ELEC/HYD maintenance page)

32
Q

Right RSVR light and R HYD QTY advisory EICAS message appear. Given these indications, you suspect a slow leak or low reservoir level. How can this be confirmed?

A

Select EICAS status page, observe Right system at .31RF
