3. Repeat steps 9 to 11 for concurrent SINS
alignment.

DEU CV ALIGN page and depressing the
VLA option key.
1. Repeat steps 1 through 7 of concurrent SINS
alignment.
2. Verify that SHDG is boxed on CV SINS DATA
MFD format.
1. Repeat step 1 and steps 4 through 8 for concurrent
SINS alignment. When the DATA pushbutton on
the MFD is depressedt,h e CV MANUAL DATA
format will appear.
2. Enter best knowledge of ship latitude, longitude,
speed and heading via the DEU or DD.
Note
Entry ofVLA isneverrequired formanual
carrier alignment.
When using the DEU, data entry is made
via the DEU CV ALIGN format, using the
LAT, LONG, CSPD, and CHDG option
keys and the appropriate quadrant and
numerals.
Data entry using the DD requires selection
of the NAV category from the MFK
pushtile and the boxing of the OWN A/C
acronym prior to entering the carrier latitude
and longitude via the DD LAT,
LONG, quadrant, and numeral pushtiles.
Entry of carrier speed and heading via the
DD requires the boxing of the WIND acronym
prior to using the DD SPD, HDG,
and numeric pushtiles.
Note
In concurrent manual carrier align, the INS
ALIGN COMPLETE computer message
may take 15m inutes or longert o appear.T he
navigation quality at this time may not be
better than 3 r&per hour. Because of the
extensive alignment time, it may be necessary
to launch prior to the receipt of the INS
ALIGN COMPLETE computer message.
8.2.2 SAHRS Standalone Carrier Alignment.
The SAHRS standalone CV alignment mode is manually
selected fmm the SAHRS ALIGN MFD format.
The WI-IRS has no true standalone carrier align mode
like the INS. During concurrent INWSAHRS carrier
align modes, the SAHRS depends upon the INS to provide
an initial input of true heading. Since this is not
availablei n SAHRS standalonec arrier alignment,w hen
the SAHRS CV pushbutton is depressed in SAHRS
standaloneo peration, it is commandedt o a DG mode.
Once the parking brake is released a DG heading can be
entered via the DEU. When the aircraft is airborne, the
slaved mode can be selected or if a system velocity
sourcei s present,i n-flight restartc an be selectedt o bring
the SAHRS to a normal operational mode.
8.3 TAXIING
Shipboard taxi operations differ slightly from the
field. Taxiingaboardship requires higherpower settings
and must be conducted under positive control of a plane
director. Any signal from the plane director above the
waist is intended for the pilot and any signal below the
waist is intended for deck-handling personnel.
8.3.1 Nosewheel Steering. The nosewheel steering
systemc haracteristicsa re excellenta nd enablee xtremely
tight cornering capability. At full nosewheel steering deflection
(709, the inside mainmount wheel backs down
and turn radius will be restricted if the inside brake is
locked. For a minimum radius turn, momentarily depress
the brake on the inside wheel and then allow the inside
wheel to roll t?eely while controlling the turn late by braking
the outside wheel. For normal turns, symmetric brake
applicationss houldb e appliedt o control aircraftf orward
motion. Forward motion should bc initiated before effccting
a tight radius turn to reduce power requirements.
8.3.2 Taxi Speed. Taxi speed should be kept under
control at all times, especially on wet decks and approaching
the catapult area. Be prepared to use the parking
brake should normal braking fail. While taxiing,
both ejection seats should be armed. The parking brake
is an excellent feature that may be used to prevent leg
fatigue during taxi delays. However, it should not be
usedo nce.f orward of the jet-blast deflector.

8.4 CATAPULT HOOKUP (DAY)
Set the attitude displays to show level flight at normal
strut extension. Proper positioning on the catapult is
easily accomplished if the entry is made with only
enough power to maintain forward motion and if the
plane director signals are followed explicitly.
pii-,,,,,,,
. All functional checks shall be performed
before taxiing onto the catapult. Ensure
that theTakeoffChecklist is completeand
that the proper trim is set for launch before
entering the nosetow approach ramp.
l All catapult launches shall be conducted
with the HUD in the caged mode. If approaching
the catapult after an uncaged
HUD landing, cycle the TLN display
mode button to ensure the HUD defaults
to the caged format.
The catapult director will direct the pilot to approach
