Hydraulic Flashcards
What is going to prevent the leading edge flaps from extending
What is the purpose of the power transfer unit
Provides additional fluid volume to the auto slats and leading edge flaps when the B system engine pump output is low
What is the minimum pressure for hydraulic system A and B 
3000 psi
Which hydraulic system reservoir is larger
B
How is and pressure and fluid quantity maintained on the standby system reservoir
By an interconnecting balance line from the B reservoir
What’s the systems are associated with hydraulic system A
A real giant p
Ailerons, Rudder, Elevator, Autopilot A, Landing gear, Ground spoilers, Inboard flight spoilers, alternate brakes, nose wheel steering, thrust reverser left, Power transfer unit(PTU)
What systems are associated with hydraulic system B
A real toy bat L
Ailerons, rudder, elevator, autopilot B, Leading edge devices, Trailing edge flaps, Outboard flight spoiler, Yaw damper, brakes, auto brakes, thrust reverser right, landing gear transfer unit
What happens when the alternate flap switch is moved to the arm position
The standby motor pump activates, the alternate flaps uptown switches armed, and the trailing edge flaps bypass valve is closed
What does the standby hydraulic system provide 
This stand by hydraulic system provides back up hydraulic pressure to the rudder thrust reverser and to extend leading edge devices When system A and B or both have failed
Explain the flight control switches 
CAAMOLY
closes flight control shut off valve, activates standby hydraulic pump,
arms low pressure light, makes flight control system light a standby rudder valve position light, opens standby rudder valve,
lights standby rudder on, 
Yaw damper - only “B” STBY RUD switch and illuminates the yaw damper light
What happens when standby flight control “A” switch is in the standby rudder position
Closes the system shut off valve, Open the standby rotor shut off valve, and powers the standby motor pump.
The standby rotor online illuminates when the standby rutter PCU is pressurized
