aircraft are spotted too close together to allow the
wings to be swept forward while tied down. Cranking

8.2.1 Carrier Alignment. Carrier alignment of the
INS and SAHRS concurrently or of the INS alone can
be accomplished using SINS data or manually entered
ship’s position, speed, and heading. A stored heading
SINS alignment is also available.
8.2.1.1 Concurrent SINS Alignment. For either
data-link or deck-edge-cabletr ansmissiono f SINS data:
1. Ensure SAHRS AC/DC cb’s (lA3,lAS, lA6,913)
are pulled prior to application of electrical power.
2. DATA LINK power switch-ON.
3. DATA LINK MODE switch - CAINSWPT.
4. Verify parking brake is set.
Note
Application of SAHRS power prior to selecting
CV ALIGN will not allow SAHRS to
properly align.
5. NAV MODE switch - CV ALIGN.
6. Reset SAHRS cb’s.
7. Select OWN A/C MFD format by depressing
DATA pushbutton on MFD MENU1 display. The
CV SINS DATA format will appear.

8. Verify that SHDG is not boxed. If it is, depressth e
SHDG pushbutton to unbox it.
9. Monitor the progress of alignment by observing
the QUAL and TIME acronyms and the align scale
on the MFD OWN A/C format. The SINS (ship)
latitude, longitude, and INS north and east velocities
can be evaluated on the MFD OWN A/C format.
An INS ALIGN COMPLETE message will
normally occur in 7 minutes. At this time the align
quality should be below 1 nm per hour.
8.2.1.2 Concurrent SINS Stored Heading Carrier
Alignment. Perform a reference alignment by
following the SINS carrier align procedurein paragraph
8.2.1.1. When the INS ALIGN COMPLETE message
appears on the HUDiVDI formats, return the NAV
MODE switch to OFF.
Note
Do not select SAHRS during CV ALIGN to
check alignment progress. Wait until INS
alignment is complete and INS has been selected
on the NAV MODE switch before selecting
SAHRS.
10. SAHRS alignment progress may be monitored at
this time by selecting the NAV page.
Note

8.2.1.3 Concurrent Manual Carrier Alignment.
Manual carrier alignment should be used only when
SINS data or the SINS carrier align mode is unavailable.
This can be determinedb y the appearanceo f the CV

CV align being initiated, the SAHRS may
complete a ground align (NORM) and a
SAHRS complete messagea ppearso n the
MFD. After the INS CV align is initiated,
the SAHRS will initiate a concurrent CV
align normally, but another SAHRS align
complete message may not occur.
11. It is advisable to continue alignment after appearance
of the INS ALIGN COMPLETE messageif
time permits. When ready to take the alignment,
the inertial navigation mode may be selected by
setting the NAV MODE switch to INS.
Note
Although SINS alignment normally requires
no entry of data, if a SINS alignment takes
place at any carrier location other than the
flight deck, then it is advisable to enter the
correct vertical lever arm via the DEU. This
is the height in feet of the aircraft INS above
the carrier SINS location. This entry can be
made only via the DEU by calling up the
