How many motive flow ejector pumps are there? What are their names?
8 Ejectors
* 2 Transfer Ejectors
* 4 Scavenge Ejectors
* 2 Main Ejectors
38
Explain the use of the Transfer Ejectors...
Transfer ejectors are use to empty the center tank. This is controlled by motive flow created by main ejectors Transfer ejectors sends fuel from the center tank (when in use) to the Main Tank. They automatically are activated when the main tank drops to 94% of fuel capacity (on the respective side). The FSC (Fuel System Computer) will open the respective transfer valve, then close the respective transfer valve when the tank is full This process continues until the center tank is empty
39
Explain the use of the scavenge ejectors...
Scavenge ejectors takes fuel from the main tanks to the collector tanks 2 per main tank (Synoptics page only shows one) Gravity line connects the main tanks to the collector tanks to act as redundancy in case the scavenge ejectors fail
40
Explain the use of main ejectors...
Two main ejectors are operated by motive flow created by the the engine driven fuel pumps Main ejectors takes fuel from the collector tank and delivers fuel to the engine
41

The associated engine will quit due to lack of fuel.
42
What is the purpose of the Fuel Boost pumps?
Acts as a back up to the main ejectors, when low pressure is detected Moves fuel from the collector tanks to engines during engine start
43
How are the fuel boost pumps powered?
Electricity (electric boost pumps) DC powered
44
How will the Boost Pumps turn on?
1. They need to be "ARMED" (pushed in)
2. They need to sense a lower pressure from the main ejector on that side (by the Fuel System Computer)
3. When one boost pump turns ON they BOTH TURN ON! (If the left and right boost pump are pushed in "ARMED" and the left engine is running, but the right engine is NOT running, the right boost pump is sensing a LOW PRESSURE on that side, meaning it will TURN ON, this will make the LEFT fuel boost pump turn on as well... Being able to send fuel under low pressure to start the #2 (right) engine)
45

48
When does the XFLOW pump automatically activates?
Imbalance of 200 lbs is detected
49
When does the XFLOW pump in AUTO mode automatically shutoff?
When the computer senses tanks are balanced plus 50 lbs on the low side
50
Regarding the fuel system, when will you use manual cross flow?
When directed by the QRH, and example of when we would do this is when the AUTO XFLOW FAILS
51
Regarding fuel system, when will you use gravity cross flow?
When the XFLOW pump has failed - Selecting the switchlight will allow the SOV to open, and gravity to balance the tanks. - Put the plane into a side slip or "turn" to help the movement of fuel

225
What is the line called to escape from crew hatch?
Escape rope
226
What is the angle of attack vane used for?
Stall Protection
227
What probes are heated on ground? And flight?
Ground - TAT and pitot bases - OFF - Static and AOA - ON - Pitot heads - half heat In-Flight/any switch position - All probes heated (w/ at least one generator online)
228
What is the pressure for the Oxygen Blowout Disc?
2800 PSI
229
Why is there a white circle around the static port?
To make sure there’s no dings or dents - will affect the readings
230
Explain the Ice Detector?
The probe vibrates at 28-30 thousand hertz frequency and when ice accumulates the frequency slows down as ice accumulates on the probe to a value. This triggers ICE caution message and ICE DET switchlight on the overhead panel. Probe will deice electrically automatically for 5 seconds during each 60 second period
231
Why are the tires chine?

235
When does the ADG Auto deploy?
When AC BUS 1 and 2 lose power
236
What does the ADG power?
- AC Essential Bus - Hydraulic 3B pump - Flaps/Slats - STAB trim Channel 2
237
What speed do you need to be configured by to prevent a ADG stall?
140 Knots
238
What speed will the ADG load shed? What will it load shed?
Between 155-160 knots The DC ESS bus will load shed the ESS TRU 1 and 2 XFLOW pump Left Probe Heaters Window Heat
239
What are the sources for DC power?
Main battery - 24 volts, 17 amps APU battery - 24 volts, 43 amps
