Flight Control System
b.
Speed brakes may not fully extend above
340 KIAS
c.
Pressure and thermal relief valves protect
system from excessive air loads and pressure
buildup due to heat
d.
Speed brake advisory light is illuminated
anytime the speed brakes are not fully retracted
e.
Cockpit selecting RETRACT overrides cockpit
selecting EXTEND
f.
No redundant system for speed brakes in event
of HYD 1 failure
D.
Summary:
The flap/slat and speed brake systems are hydraulically
operated. The speed brakes have a blow-back feature.
The flaps have three positions, UP, 1/2, and DN. The
slats are retracted when the FLAPS/SLATS switch is set
to UP and extend when the FLAPS/SLATS switch is set
to 1/2 or DN
