PTP on the reconnaissanceM FD RECON DATA status
format. At this time, all steering cues are removed from
the HUD and VJX. In addition, the DSPT (waypoint 17)
is removed from the HUD.
22.4.3.2 Command Course Steering. CCRS is
selectable if the navigation system is properly operating
and the selected waypoint to be reconnoitered has a
nonzero value for target length. When the above conditions
are satisfied, the selection of CCRS on the h4FD
RECON DATA status format will box CCRS. Immediately
following that, TARPS will compute the DSPT,
which is displayed on the HSD format, and the complete
set of steeringc ues( the reconnaissancset eerings ymbol,
CGTL, reconnaissanctea rgetd esignator,a nd recotmaissame
command heading marker) to guide the aircraft to
fly over the target at a command crossing angle (stored
in the waypoint file). When the aircraft approachesth e
wings-level position (indicated when the DSPT initiates
movement to the target), the CGTL will appear to provide
additiona visual cues for proper target crossing.
Note
PTP would be selected (instead of CCRS) if
the target length is zero.
CCRS steering is deselected when the aircmfi has
flown the target length (stored in the waypoint file) past
the target or when the crew manually deselects CCRS
on the MFD RECON DATA status format. As in PTP,
all steering cues are removed from the HUD and VDI.
In addition, the DSPT (waypoint 17) is removed from
the HSD.
22.4.3.3 Mapping Steering. MAP is selectableunder
the following conditions:
1. Navigation system is properly operating.
2. The selected waypoint to be reconnoitered has a
nonzero value for target length.

3. The two ma* parameters, map offset (separation
distance between adjacent map legs) and map
lines, are nonzero values.
When the above conditions are satisfied, the selection
of MAP on the MFD RECON DATA status format will
box MAP. TARPS will then compute the DSPT (displayed
on the HSD) and the complete set ofsteering cues
(the reconnaissances teerings ymbol, CGTL, reconnaissancet
arget designator,a nd reconnaissancec ommand
heading marker).
MAP steering includes guidance through the required
90° to 270” tum maneuvers, using command heading
and steerings ymbology, for the necessaryre turn legs of
the reconnaissancem issions.
Note
l PTP would be selected if only condition 1
was valid. Insufficient parameters are
available for mapping.
l CCRS would be selected if only conditions
1 and 2 were valid.
MAP is deselected at the completion of the last map
leg or when manually deselected by the crew on the
MFD RECON DATA status format. When MAP is deselected,
t he following will occur: removal of the reconnaissance
overlay symbols (CGTL, reconnaissance
command heading marker, racotissance target designator,
and reconnaissance steering symbol) from the
HUDandVDI;removaloftheDSPT~mtheHSD,and
MAP LINES REM (on the MFD RECON DATA status
format) will be zero.
22.4.4 HUDNDI Symbology. TheHuDMXsymbology
is available when there is a valid selection of
reconnaissances teering.T his symbology consistso f the
following timctions:
1. Displays recommissances teeringc ues and sensor
status to the HUD when valid steering is selected
and the a&&l is not in A/A with a weapon selected
(Figures 22-8 and 22-9).
2. Displays reconnaissances teeringc ueso n the VDI
when the VDI is selected (Figure 22-8).
The H’UD/VDI symbols are listed and displayed in
Figures 22-8,22-g, and 22-10.
22.5 RECONNAISSANCE SYSTEM
OPERATION
The RIO is primarily responsible for the entry of re
connaissancep arametersf or waypoints and selection/
operation of TARPS sensors. In addition, the RIO may
assist in updating the INS just prior to flying over the
target and plotting the target leg (im CCRS and MAP
modes) on the HSD.
