Term
| How many pumps are found in each tank and what are they called? |
|
Definition
Three; one ejector pump, one scavenge ejector pump, one electric fuel boost
pump. |
|
|
Term
What is normally used to supply fuel from the wing to the engine fuel control
unit in flight? |
|
Definition
|
|
Term
| How is the primary fuel ejector pump powered? |
|
Definition
| Motive flow from the respective engine. |
|
|
Term
| What is the primary purpose of the scavenge jet pump? |
|
Definition
Maintains the fuel level in the collector tank ensuring a constant flow of fuel to the
engine during normal flight |
|
|
Term
| When is the electric fuel pump activated if in the auto position? |
|
Definition
| Engine start, crossfeed operation, if primary ejector pump fails. |
|
|
Term
What ensures that the differential pressure between the tank and ambient
remains within structural limits and prevents fuel spillage? |
|
Definition
| A vent system including a NACA air inlet/outlet. |
|
|
Term
| How is crossfeeding performed? |
|
Definition
Select the XFEED switch to the wing tank with the low fuel quantity
(LO 1 or LO 2). This opens the XFEED valve and turns on the electric DC pump in
the wing tank with the highest level of fuel. Both engines will utilize fuel from that
tank. |
|
|
Term
| What is the restriction on crossfeed operation? |
|
Definition
| Shall not be performed during takeoff and landing |
|
|
Term
When fuel becomes balanced and the XFEED valve is still open, what CAS
message will be annunciated? |
|
Definition
|
|
Term
Will the total tank quantity indication be lost if only one wing tank quantity
indicator fails? |
|
Definition
|
|
Term
The fuel shutoff valves are normally open. What is the only way to close one of
these valves? |
|
Definition
| By pushing the fire shutoff pushbutton. |
|
|
Term
| What would cause a “FUEL LO LEVEL” CAS message? |
|
Definition
| 310 lbs of fuel remaining in the respective tank |
|
|
Term
| What would cause a “FUEL IMBALANCE” CAS message? |
|
Definition
|
|
Term
| Is there de-fueling capability? |
|
Definition
| Yes, by means of a dump valve located under each wing. |
|
|
Term
While fueling, what monitors the fuel quantity in the tanks and controls
refueling flow into each tank? |
|
Definition
| EFCU, Electronic Fuel Control Unit. |
|
|
Term
| How long is maximum refueling time from empty to full? |
|
Definition
| Less than 12 min, at 50 psig. |
|
|
Term
Explain the two critical tests that should be accomplished on the control panel
before re-fueling begins? |
|
Definition
Lamp Test – When the LAMP TEST switch is held up, the LH TANK and RH TANK
indicator lights stay on or come on according to the status of these lights, the FAIL
indicator light turns on and the digits light up.
Shut-Off Test – When the SHUT-OFF TEST switch is held up during pressure
refueling operation, the LH TANK and RH TANK indicator lights must come on,
indicating that the shut-off valve closes, and the FAIL indicator light must be off |
|
|
Term
What action is necessary to accomplish on the refueling panel if external power
is not being utilized? |
|
Definition
| The POWER SWITCH must be selected to BATT. |
