can be stored in the waypoint file at any time. The
primary parameters that may be entered for each waypoint
are longitude, latitude, and altitude. These may be
entered manually via the DEU by selecting the DEU
WPT page (Figure 20-19) and depressing fhe desired
waypoint numberp rior to enteringt he coordinates.V eri-

fication of correct entry can be made by examining the
MFD WPT DATA format, selectable by depressing
WPTS (PB7) on the MFD OWN A/C format and shown
in Figure 20-20.

The DD control panel may also be used for entering
these parameters for waypoints 1 to 20. When the DD
control panel is used, on the main menu, press the WP
l-10 or WP 1 l-20 pushtile and then box the desired
waypoint. The coordinates are entered using the quadrant
and numeric pushtiles on the lower left portion of
the DD control panel, as indicated on Figure 20-21.
The primary waypoint parameters and their ranges
are as follows:
WPT Primary
Parameter
Longitude
Latitude
Altitude
Range
E/W 180”
N/S 90”
-5000 to 99,996 feet
In addition to the above primary waypoint pammeters,

steering function may also be entered when the specified
waypoint is to be useda s a reconnaissanceta rgetp oint.
These parametersh, owever, can only be enteredv ia fhe

During on-deck carrier operations, some waypoint
data can be automatically provided from fhe DiL. if provisions
on the carrier have been made. This is called
waypoint insertion. The D/L must be operating with the
reply panel MODE switch in CAINS/WPT. The NAV
MODE switch should be in any position other than CV.
For these conditions, the latitude and longitude of up to
the first 16 waypoints may be received.
20.3.4.2.1 Waypoint Data File Use. In general
the 100 waypoints can be used in any manner described 1
inparagraph20.3.6, TacticalNavigation, fordestination
steering or for the one-fix updating functions. Usually,
however, certain of these points are reserved for special
functions.
Waypoint 1 is usually reserved for homebase coordinates.
Its data is retained after use.
Waypoint 17 is used as a dynamic steering point
when a reconnaissances teering mode is selectedu sing
the MFD RECON DATA format. At this time any previously
stored data in waypoint 17 become invalid and
must be reentered.
Waypoint 18 is used for the coordinates of an agreed
point for data-link one-fix position update. Its data are
still valid after update usage.
Waypoint 19 is used for the coordinates of the fighter
link reference point, as described in the Supplemental
NATOPS Flight Manual, NAVAIR Ol-F14AAD-1A.
Its data are still valid after usage for “FLRP.”
Waypoint 20 is usually reserved for the approximate
location and altitude of a hostile area. Its data are retained
after use.
Waypoints 2 to 16 and 21 to 100 are general way- 1
points and are used as required by the mission. The data
of these points are retained after use.

re normally generatedb y the navigation system
using air data and INS or SAHRS velocities. When
the navigation system cannot compute wind because of
unavailability of the required velocity inputs, it will accept
manual entries of wind from the DEU or the DD
control panel. Entry ofwind can be made priorto takeoff
with no sensor failure since CADC true airspeed is not
set valid until it reaches approximately 60 knots.
