Study Notes

Landing Gear Hydraulic System

An electrically powered pump located in the aft fuselage supplies hydraulic fluid to the landing gear actuating cylinders
The pump is located between fuselage stations 156 and 191
The pump has an integrated reservoir
The pump is controlled by a selector switch on the instrument panel
There are dedicated pressure lines for each individual actuating cylinder
The pump directs fluid through these lines based on the position of the selector switch
The same lines serve as either pressure or return passages depending on the pump rotation, which determines gear extension or retraction
