simultaneously. If the anti-skid
system is selected ON it will
operate normally with parking
brake application.
(c) The BRK PRESS caution light
illuminates when there is a
failure in the brake pressure
release system, ie., brake
pressure is available. The
light may also illuminate in
flight with the landing gear UP
due to a single component
failure. However, if the BRK
PRESS light illuminates due
to indicator circuit failure, the
brake system will function
normally, ie., brake pressure
is available. A loss of brake
pressure could only result
from a simultaneous failure of
more than one component.
An unlikely probability, this
makes the risk acceptably
low. Most likely brake
pressure WILL be available
and a normal approach and
landing can be anticipated.
Also, a momentary
illumination MAY OCCUR
when the launch bar
transitions to the RETRACT
position following catapult
launch, during non-catapult
operation (line check), or
during landing gear extension.
Assume normal braking is
available if the light
extinguishes after the
transition period.
NOTE: If the BRK PRESS
caution light illuminates on the
catapult with all prelaunch
