conditions met, ie., aircraft in
tension, throttle above 95%,
LAUNCH BAR switch selected
to RETRACT, NWS button
NOT depressed, parking brake

THE CATAPULT AND ABORT
THE LAUNCH!
(4) Limitations: During normal carrier
and field operations, the BRK
PRESS cation light should not be
illuminated. The light should only
illuminate when indicating a
system or indicator circuit failure.
If the light illuminates with all
prelaunch conditions met-
SUSPEND THE CATAPULT
(5) Summary:
The brake pressure release
system was devised with the
purpose of preventing the
possibility of tire blow-out during
the catapult launch and then
dealing with the emergency
arresting landing scenario resulting
from that blown tire. Remember
that "no lights" is what to look for
prior to launch. All prelaunch
conditions must be met in order for
the brake pressure to release
