Interface summary:
The hydraulic subsystems interface with the
following four basic aircraft systems: HYD 1,
electrical system, CWS, and the WOW sensors.
Additionally, the position of the landing gear
affects the operation of various aircraft systems.
All hydraulic subsystems are powered by HYD 1
hydraulic pressure. If HYD 1 fails, the following
subsystems rely on emergency backup systems:
landing gear/gear door extension, forward NLG
door closure, arresting hook extension, wheel
brakes, and flaps. The following subsystem
