Fuel Flashcards
What is the fuel capacity?
5,717 lbs per wing,
11,434 lbs total.
AOM 2-08-05 page 2
If the aircraft is fueled by pressure refueling, can the maximum capacity be reached?
No. The usable fuel quantity in each tank may be reduced by 13.2 US Gal.
AOM 1-01-36 page 1.
How many electric pumps are in each collector box?
3
AOM 2-08-05 page 3.
If no electric pump is available to provide fuel to an engine, the engine-driven pumps can suction feed up to what altitude?
25,000 ft
AOM 2-08-05 page 3.
When must the crossfeed selector be OFF?
During takeoff and go-around.
AOM 2-08-05 page 3.
If an electric fuel pump is switched on automatically due to a drop in pressure, how does it operate?
It will cycle on and off until selected on the overhead panel (wing tank pump indication blinks when cycling).
AOM 2-08-05 page 3.
What happens if LOW1 is selected with the crossfeed valve?
The selected electric pump on the left side is deenergized and the crossfeed valve opens. AOM 2-08-05 page 3.
Fuel for the APU is normally provided from which wing?
The right wing.
AOM 2-08-5 page 4.
Can the APU be supplied with fuel from the left wing?
Yes. The crossfeed selector must be selected to the LOW2 position. AOM 2-08-05 page 4
When does the FUEL IMBALANCE Caution message appear, and when will it extinguish?
When fuel quantity in one tank differs by 800 lbs from the other tank. The message is removed when the difference between the tanks is less than 100 lbs. AOM 2-08-05 page 7.
What is the power source for pressure refueling?
The power source is selected on the refueling panel. Normally, DC Bus 1 is the power source, energized by the batteries, APU, GPU or running engine. If BATTERY is selected on the refueling panel, HOT DC Bus 1 is the power source. AOM 2-08-10 page 4.
How many fuel measuring sticks does the LR model have?
3 per wing (two under each wing and one for the stub tank). AOM 2-08-15 page 1.
Explain how to use the fuel measuring sticks.
Start using the stick closest to the wing tip. Using the charts provided in the AOM, convert the stick indication to a fuel quantity. If the outermost stick reads zero, move to the internal stick and repeat the process. Do not add measuring stick values. It is necessary to wait 10 minutes after refueling or after the fuel pumps are turned OFF before reading the sticks. AOM 1-12-25 page 6.
