14.10 LAD/CANOPY LIGHTANDIOR LOSS
OF CANOPY
In the event of canopy loss in flight, the pilot will be
adequately shielded by the forward windscreen to maintain
control of the aircraft. Vision may be impaired
briefly by dust in the cockpit, and moderate head buffet
may occur, which can be alleviated by lowering the seat
and/or leaning forward. The RIO will be exposed to a
significantly more hazardous and disorienting environment,
which will include vision impairment, loss of
communications, wind blast injury, and breathing difficulties.
The degree to which these will be experienced
is directly relatedt o airspeeda nd seath eight, In addition,
the possibility of helmet loss becomes greater as airspeed
increases above 300 knots. ICS and RIO VHF/
UHF communications will probably be impossible
above 200 knots, although the pilot will be able to effectively
utilize V/UHF at airspeeds up to approximately
400 knots. After lowering the seat, the RIO should lean
forward to take advantage of the wind blast protection
provided by the detail display and instrument panel,
while the pilot deceleratest he aircraft by utilizing idle
power, speedbrakesa, nd moderateg . The RIO should
deselect HOT MIC ICS to prevent interference with
VNHF communications caused by wind blast across
the oxygen mask microphone. Helmet loss will result in
severe disorientation because of a total loss of communications
and vision impairment caused by wind blast.
If canopy loss is experienced at high speed, or if
helmet loss.appearsto be possibleb ecauseo f wind blast
or buffeting, retain the helmet by pulling down on the
visor cover (keeping arms close to the body).
The pilot LAD/CANOPY caution light may be activated
by a mispositioning of either the boarding ladder
or the canopy. If both the pilot LAD/CANOPY and the
RIO CANOPY lights are illuminated, then the problem
is with the canopy system. If the RIO CANOPY light is
working but not illuminated, then the problem is with
the boarding ladder.
m
If both the pilot and RIO caution lights are
illuminated, indicating a canopy problem, a
later problem with the boarding ladder will
not activate the LAD/CANOPY or the MASTER
CAUTION lights.
Note
Ifthe RIO CANOPY light is not illuminated,
ensure that it is operating by selecting IND
LT on the RIO TEST panel before assuming
a boarding ladder problem.

CANOPY Light/Canopy Loss
* 1. Canopy - Boost Close (canopy remaining).
*2. EJECT CMD lever-PILOT.
3. Airspeedandaltitude-Below200Knots/ 15,000

4. Seats and visors -Down.
5. If canopy has departed aircraft, perform controllability
check.
6. Land as soon as possible.

If hammering (cavitation) is experienced in
the hydraulic system, component rupture is
imminent. Turn the hydraulic transfer pump
switch (BIDI) OFF.
1. HYD ISOL switch - FLT.
Note
Monitor AUX BRAKE PRESSURE gauge.
Tap wheelbrakes to seat priority valve if
pressure is decreasing.
2. In-flight refueling PROBE switch - EXTD (in
carrier environment).
3. Wing sweep - Set at 20”
4. L INLET RAMPS switch-STOW (less than 1.2
Mach).
5. Left AICS cb - Pull (LFl).
If WING SWEEP advisory light is illuminated,
pulling L AICS cb (LFl) may cause
unintentional wing sweep unless WING

7. DLC - Do Not Engage.
8. EMERG FLT HYD switch - HIGH (on final,
committed to landing).
9. Land as soon as possible.
. Loss of combined pressure may indicate
impending fluid loss. Without fluid in the
combined system rehrn line, the in-flight
refueling probe will not extend with the
handpump.E arly extensiono f the refueling
probe at the first indication of a combined
system malfunction is recommended in a
carrier environment.
. Monitorremaininghydraulicsystempressure
since the MASTER CAUTION and
HYD PRESS lights will not illuminate if
the remaining systems fail.
Note
To extend or retract the refueling probe using
the hydraulic handpump requires the landing
gear handle to be in the up position, combined
