Engineering Review
e.
De-spin actuator: signals brake control valve to
apply hydraulic power to brake units to stop
wheel rotation when gear handle is raised
f.
Parking brake: mechanically operates brake
control valve to apply hydraulic pressure
simultaneously to both wheel brake units to
park aircraft
g.
Anti-skid control box: “brains” of anti-skid
system; controls operation of anti-skid valve
h.
Speed sensors: measure rotation speed of
each wheel; resulting signal sent to anti-skid
control box and used to predict when a wheel is
about to skid
i.
Wheel brake/emergency flap accumulator:
provides smooth, even brake response with
HYD 1 operational; provides 10 full brake
applications in the event of HYD 1 failure with
anti-skid off
2.
Controls and indicators
a.
Brake pedals
b.
BRAKE pressure gauge and wheel brake/
emergency flap accumulator pressure gauge
indicate pressure in wheel brake/emergency
flap accumulator
c.
PARKING BRAKE caution light: illuminates
when parking brake is engaged and throttle is
past 70% rpm
d.
PARKING BRAKE handle
e.
ANTI-SKID switch
f.
SKID caution light
g.
SKID advisory light
