Engineering Review
(2) When set to FIELD, above function is
bypassed and lights are steady
NOTE: The HOOK BYPASS switch does
not affect the operation of the arresting
hook. Instead, it controls the operation of
the AOA indexer and approach lights and
serves as a reminder to lower the hook
during arrested landings.

Hydraulic system
a.
All hydraulic subsystem items powered by
HYD 1
b.
If HYD 1 fails, services retained due to backup/
alternate means include
(1) Landing gear/doors: gravity free-fall
extension and lock
(2) Forward NLG doors partially close
electrically
(3) Arresting hook: gravity/pneumatic
extension
(4) Wheel brakes: wheel brake/emergency
flap accumulator provides enough braking
for one normal landing (a minimum of 10
brake applications)
(5) Flaps: full extension with wheel brake/
emergency flap accumulator pressure >
2200 psi
c.
If HYD 1 fails, services lost include
(1) NWS: use differential braking instead
