hydraulics Flashcards
what components are on both hydraulic systems
6
slats,flaps,rudder stop limiter , nose wheel steering,brakes and anti-skid
what components are on the right hydraulic system
4
Left and right outboard spoilers,the rudder, the right t/r and the landing gear
what components are on the left hydraulic system
3
left and right inboard spoilers,left t/r , elevator aug
what is the function of the auxiliary hyd pump what overheat protection
backup to right engine pump to pressurize the system on the ground when engines not running
shuts down if overheat
what is the hyd pump pressure and what if power is removed
3000psi goes to on if switch is then moved to off the pump will turn off.
what does p by the pump symbol mean
low pump pressure
what powers the aux hyd pump
left gen bus
what is the cyan color on the hyd sd display
preflight hyd fluid level
what is min hyd quantity for flight
7
inoperative components with complete hyd loss
6
flaps and slats will remain in last position, Speed brakes/ground spoilers not available,rudder manual ,emergency gear extension required,tr will not stow
5 things
function of the hyd transfer pump
pressurized system to mechanically transfer power to pressurized system
OFF- closes valve on each side of PTU
On opens valve on each side
How to determine if hydraulic quantities are adequate
reservoirs guantity is displayed by shading
fixed quantity reference line appears after engine start
Hydraulic digital quantity
White within limits
Amber Fluid levels below limits
Pre-flight Hydraulic Level CYAN
Cyan -Normal
hyd pumps operating during electrical failure
pumps default to on off switch still works
min preflight quantity
7
Hyd system test first flight
SDCP HYD cue Aux puma-on aux puma turns green and pressure normal Trans pump switch on turns green and pressure normal Trans and Aux off
