With the aircraft, completely full of fuel, discuss the different field, configurations, beginning with engine start through landing
On ground
After engineer – CWT pumps were selected on before start because there was more than 17,000 pounds in the CWT. All engines are fed from CWT by the CWT override/jettison pumps through the crossfeed manifold.
The two and three main tank override/jettison pumps are armed because the CWT space override/jettison pumps are on. All main tank boost pumps are on, but overridden by the higher pressure from the CWT.
2.
Setting T/O flaps crusted valves, two and three clothes with system. Logic engines, one and four are fed from CWT by the CWT override/jettison pumps. Engines two and three are fed from their respective tanks by their respective main tank boost pumps. The main tank override/jettison pumps remain armed, because CWT override/jettison pumps are on.
Climb
Flaps up – system logic opens two and three crossfeed valves. All engines are once again fed by the CWT override/jettison pumps out of CWT.
Less than 7000 pounds in CWT during climb this condition is rare and will only occur when departing with not much more than 17,000 pounds in the center wing tank. The fuel pulled in the back of the CWT, while the pumps are near the front, and we don’t want them to cavitate. CAS fuel low CTR space L/R space comes on, and when we turn off the CWT pumps. The armed main tank two and three over ride/jettison pumps, turn on, and feed all four engines through the crossfeed manifold.
Cruise
Greater than 4000 pounds of fuel and CWT previous steps, was accomplished during climb. The EICAS message fuel OVD cTR L/R. Displays after the aircraft levels off and accelerates pitch less than 5° directing us to turn the center wing tank override jettison pumps back on.
Less than 3000 pounds fuel in center win tank the message feel low CTR space L/R space displays on EICAS. Space CWT space pumps must be turned back off. That 3000 pounds remaining in the center wing tank for several hours override jettison pumps from main tanks, two and 3 feet all four engines through the cross feed manifold Engines one and two receive field from the number two main tank and engines three and four receive fill from the number three main tank due to proximity to the pump. The two sides are now isolated from each other.
Less than 40, 2200 pounds in the inboard main tanks, reserve tanks two and three begin to transfer to main tanks two and three transfer valves stay open for the remainder of the flight the CT scavenge activates to salvage the remaining 3000 LBS transferred to maintain tanks. Number two. It will run for 120 minutes or until low pressure is sensed ?
When all main tank quantities are approximately even 29,000 pounds EICAS message field tank to engine display select override pump off and then close one and four Crossfields in the order EICAS message will blank upon closing crossfeed bels even if you forget to turn off the override pumps, the aircraft is in tank hundred configuration with the main tank, boost pumps, feeding each engine from its respective tank for the rest of the flight
How do we and what happens when we jettison fuel
What is the difference between total feel, and calculated fuel? When are the values different?
Total calculated is what the field quantity system is reading in the tanks calculated fuel calculation of the that should remain based on how much the engine have used
A few league will make these values different significantly

Armed, even though the switches are on
What is the max feel balance between one and four and two and three?
EICAS message feel imbalance 1–4 comes on at a difference of 3000 pounds
EICAS message fuel imbalance one and four comes on at a difference of 6000 pounds
What is the purpose of the number one and four transfer valves?
Open to allow gravity transfer from outboard to inboard main tanks will transfer until approximately 7000 pounds between each outboard tank
Automatically opened during jettison one main tanks, two and three have less than 20,000 pounds
Those me be open manually using the field, transform main one and four switch on the overhead panel, but this is normally just a maintains function to correct in balance on the ground
Does the flow bar disappear on the crossfeed two and for transfer valves?
No flow bar in the end board crossfeed, just means that the valve is controlled by system logic not necessarily that it is open
After position the field jettison selector to a or B, where does the fuelto remain value display
Replaces field temp on the primary EICAS
