Fuel & Warning Systems Flashcards
What is the surge bay used for?
main tank venting and fuel recovery allowing for positive pressure in the fuel tanks
How is the surge bay vented?
to two NACA vents
Total usable fuel ?
11,724
How does the collector bay gather fuel from the main tank?
scavenge ejector pumps and flapper valves
What provides low pressure/high volume fuel supply to the Fuel Metering Unit (FMU)?
Primary Ejector Pump in the collector bay
What serves as a backup source of fuel boost pressure?
two AC powered auxiliary fuel pumps, one mounted on the floor of each collector bay
1 or #2 ENG FUEL PRESS
caution light indicates…
pressure at engine driven pump inlet is low
1 of #2 FUEL FLT BYPASS
caution light indicates…
engine fuel line has bypassed the filter
1 or #2 TANK FUEL LOW
caution light indicates…
fuel senses 305 lbs of fuel remaining in collector tank
FUELING ON
light indicates…
Refueling/Defueling panel access panel is open and power is applied to the panel
How is fuel quantity determined?
a Fuel Quantity Computer uses nine capacitance-type fuel probes in each tank, or magnasticks on the underside of each tank
What do
Warning Tone Generators
do?
The two WTGs generate and prioritize failures. EGPWS/TCAS/Alerts
What will trigger a
takeoff warning horn?
- Elevator TRIM out of takeoff range -
- Parking brake SET -
- Condition levers not at MAX -
- Flaps extended more than 20 degrees or less than 3.6 degrees
- Any spoilers extended
How many fuel tanks are there?
3 per wing
Surge bay, Main tank, Collector bay
The Magnasticks are accurate to what range?
15% to 85%
