Hydraulics and Fuel Flashcards
What must each Hawker Flyer know
BTFANGS
What is BTFANGS and what are all of them
all of the things that uses hydraulics
B-brakes
T-thrust reversers
F-flaps
A -airbrakes
N -nosewheel steering
G-gear
S-stick pusher
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
When will the LO PRESS annunciator extinguish
1,750 psi
what should the main accumulator pressure be at
1000 psi
what should the wheel brake accumulator be at
1000 psi
What is the total normal pressure for hydraulic
3000 psi
when will the LOS PRESS annunciator illuminate
1,500psi after a 57-second delay
if both hydraulic pumps fail what kicks in, and when
the pressure-maintaining valve will close at 2,300 psi (for brake operation)
When will the overpressure valve open
is there an indication
4,000 psi
there will be no indication
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
