Answer 11

The Left collector Bay

Question 12

Pressure refuelling is accomplished via the refuel/Defuel panel located where?

Answer 12

Underside at aft end of #2EngineNacelle

Question 13

Normal fuel temperature range on the fuel temperature gauge is what?

Answer 13

11°C to 57°C

Question 14

Usable fuel quantity is displayed on cockpit gauges in what?

Answer 14

Pounds

Question 15

Fuel is drawn from the collector Bay and delivered to the engine by what?

Answer 15

Boost ejector pump

Question 16

What kind of pump is In each collector Bay?

Answer 16

Auxiliary fuel pump

Question 17

Any residual fuel in the surge tank can be routed back to the tank in flight by what?

Answer 17

Positive ram pressure from NACA vents in the under surface of the surge tank.

Question 18

Should the fuel tank vents become blocked when will the dump valve open to relieve pressure?

Answer 18

The valve will open to relieve pressure at an interior tank pressure of 3.25 PSI

Question 19

What are the two uses for the dump valve in the fuel tanks?

Answer 19

Relieve excess pressure in the case of a vent blockage, also to release Excess fuel from the tank into the Surge Bay in the event of an overfill.

When do you get an associated tank fuel low caution light?

Answer 21

Below 130 lbs

Question 22

Which two pumps supply fuel to the engine?

Answer 22

The engine driven pump, and a boost ejector pump

Question 23

The high-pressure engine driven fuel pump is driven by what?

Answer 23

The accessory gearbox.

Question 24

Where does the boost ejector pump Draw it’s Fuel from?

Answer 24

From the collector Bay

Question 25

When does the green advisory light adjacent to the auxiliary pump switch illuminate?

Answer 25

When the auxiliary fuel pump is providing fuel boost pressure greater than 4PSI

Question 26

When does the Fuel emergency shut off valve close?

Answer 26

When the PULL fuel off handle is pulled

Question 27

On the Emergency fire protection panel how will you know if the fuel valve is closed?

Answer 27

A white closed advisory light

Question 28

If the high-pressure fuel filter becomes restricted what happens?

Answer 28

Fuel bypasses the filter to supply the engine and illuminates the respective fuel filter bypass caution light

Question 29

Pressure refuelling is normally shut off automatically when the desired tank quantity is reached if automatic shut off fails what occurs?

Answer 29

When the fuel tank fills a float in the pilot valve It will shut off servo flow causing the flow control valve to close
