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
