Hydraulic Subsystems
NOTE: The wheel brake/emergency flap
accumulator maintains hydraulic system
pressure to the brakes and flaps if HYD 1
fails. It also maintains pressure to the
parking brakes while the aircraft is on the
ground. The cockpit BRAKE pressure
gauge should read 3000 psi if HYD 1 is
operational and a minimum of 1300 psi if
HYD 1 is shut down. The gauge displays
nitrogen preload pressure or HYD 1 system
pressure trapped in the accumulator.
