There are three independent hydraulic systems that supply
hydraulic power for user systems.
The main and auxiliary hydraulic systems supply pressurized
fluid to these airplane systems:
* Both thrust
reversers
* Power transfer
unit (PTU) motor
* Landing gear
extension and retraction
* Nose wheel
steering
* Main gear brakes
* Primary flight
controls
* Secondary flight
controls.
These systems make up the hydraulic power system:
* Main hydraulic
systems
* Ground servicing
system
* Auxiliary
hydraulic systems
* Hydraulic
indicating systems.
Main Hydraulic Systems
The main hydraulic systems are A and B. System A has most of
its components on the left side of the airplane and system B on
the right side.
Ground Servicing System
The ground servicing system fills all hydraulic reservoirs from
one central location.
Auxiliary Hydraulic Systems
The auxiliary hydraulic systems are the standby hydraulic
system and the power transfer unit (PTU) system.
The standby hydraulic system is a demand system that supplies
reserve hydraulic power to these components:
* Rudder
* Leading edge
flaps and slats
* Both thrust
reversers.
The hydraulic power transfer unit (PTU) system is an alternate
source of hydraulic power for the leading edge flaps and slats
and autoslat system.
Hydraulic Indicating Systems
These are the indicating systems:
* Hydraulic fluid
quantity
* Hydraulic
pressure
* Hydraulic pump
low pressure warning
* Hydraulic fluid
overheat warning.
