HYDRAULIC SYSTEM – ATA 29. Mark only one oval. If the EDP #1 in the Green Hydraulic system is inoperative:
The Green Hydraulic System is lost
The PTU pressurizes the Green Hydraulic System
You can pressurize it by Leak Measurement Valves operation
HYDRAULIC SYSTEM – ATA 29. Mark only one oval. When is the RAT deployed automatically?
In case of an electrical emergency, loss of main AC busses 1 and 2 and airspeed greater than 100 kts
In case of a hydraulic system failure, more than two systems lost
At any moment, when the pilot pushes the push button located on the hydraulic or electrical control panel
HYDRAULIC SYSTEM – ATA 29. Mark only one oval. Can you pressurize the Blue Hydraulic system on ground with engines stopped?
Yes, by the PTU
Yes, by the Blue Pump Override pushbutton (50VU)
Yes, by the RAT
HYDRAULIC SYSTEM – ATA 29. Mark only one oval. When the pushbutton of any EDP is pushed to OFF position:
The pump is disconnected from the engine
Solenoid valve in the EDP is energized, and the pump runs in depressurized mode
Solenoid valve is de-energized, hydraulic supply to the pump is shut
