What is BTFANGS and what are all of them

all of the things that uses hydraulics
B-brakes

how many hydraulic pumps and what are they

4 hydraulic pumps
2 engine driven
1 hand pump
1 auxiliary system pump

where are the hydraulic engine pumps and what do they do

they are on the accessory case
anytime the engine is running so are these pumps
variable volume
one can operate all sub-system

what does the hydraulic hand pump do and where is it

ground pressurization
rear equipment bay

what does the hydraulic auxiliary system pump do and where is it

extend the landing gear and operate flaps
in the cockpit

Auxiliary hydraulic system

6 pint tank
provides to lower the landing gear and operate flaps
in the flight deck

Accumulator

a compressable chamber that compresses a noncompressible fluid (hydraulic pressure)
gas accumulators most common

what are the kinds of fuel pumps

electric boost pump
jet pumps
engine

Electric boost pump info

one in each wing tank - total 2
can turn them on and off
transfers fuel to the center of the wings

Jet pump info

vacuum pump - no moving parts - works on its own
4 total

weight of jet a fuel

6.7 gallons

how many wing tanks do we have

2 - one electric boost pump in each

Auxiliary ventral tank

fuel in this tank can be transferred into both wing tanks through electric boost pump

What are the fuel tanks divided by

ribs and spars

do we have e vent system

yes

what is our fuel capacity
total -
in wings -
ventral tank -

10,000 pounds
8,500 in wings
1,500 in ventral tanks

jet pumps draw fuel into the

#1 wing compartment

where do our jet pumps draw fuel from

one draws fuel from outer wing compartments

where does the electric fuel boost pump pull from what does it use to do this

pulls fuel under pressure from the same-side engine via the LP fuel cocks

if the electric boost fuel pumps fail how do we get fuel?

gravity it is still a gravity fed system

for ventral fuel how do we put it in the wings

AUX FUEL TRANSFER on both boost pump working - both tanks evenly One boost pump working - fuel transfers to operating fuel pump tank

How long does it take for ventral fuel to transfer

10 minutes with both boost pumps operating 18 minutes with one boost pump operating

if both boost pumps are not operating how do we get our ventral fuel

we don't

Where does the APU get its fuel

left tank

Where can you read fuel info

right MFD

What can the ventral tank read

EMPTY, FULL, or HASHES

when can you transfer fuel from ventral tank to the wing tanks

3,300 - allows for all the fuel to leave the ventral tank
