instant of flyover. This requires that the VIS pushbutton
be pressed at that time. The assigned coordinates are
displayed when the VIS pushbutton is pressed. This
procedure can be performed by either crewmember.
Note
For best results, the aircraft should be flown
low and slow for this procedure.
1. Call up the MFD INS UPDATE format (Figure 20-29).
2. Depress the SWP pushbutton to display the MFD
SURFACE WPT POS update format.
3. Depress the up or down arrow pushbutton until the
desired waypoint number is displayed.
4. At the instant of overflight, depress the VIS pushbutton,
boxing the VIS legend and displaying the
latitude and longitude of the surface waypoint.
5. If the latitude and longitude appear reasonable,
press the ENTER pushbutton on the SURFACE
WPT POS format. This enters the coordinates into
the waypoint file; they can be verified by selecting
the WPT DATA format (Figure 20-20).
20.3.6.4.2 Tacan Surface Waypoint Position
Determination. For tacan surface waypoint position
determination, the position of the tacan station is computed
using tacan measurements of range and bearing
from aircraft present position. This procedure can be
performed by either crewmember and requires that the
tacan be operating.
1. With the tacan operating, select the channel for the
station location to be determined.
2. Call up the INS UPDATE format (Figure 20-29).
3. Depress the SWP pushbutton to display the MFD
SURFACE WPT POS format.
4. Depress the up or down arrow pushbutton until the
desired waypoint number is displayed.
5. Depress the TCN pushbutton on the MFD SURFACE
WPT POS format. This boxes the TCN
legend and displays the tacan station latitude and
longitude.
6. If the coordinatesa ppearr easonablep, resst he ENTER
pushbutton to place the surface waypoint COordinates
into the proper waypoint file. They can
be verified by selecting the WPT DATA format
(Figure 20-20).
20.3.6.4.3 Radar Mode. For a radar surface waypoint
position determination, the position of a radar surface
target is computed using radar measurements of
range, bearing, and elevation angle to the target from the
known aircraft present position. The radar must be in the
GND MAP mode. This procedure can only be performed
by the RIO.
1. On the DD control panel, select GND MAP.
2. Call up the INS UPDATE format (Figure 20-29).
3. Depress the SWP pushbutton, which results in the
display of the SURFACE WPT POS format with
SWP boxed.
4. Depress the up or down arrow pushbutton until the
desired waypoint number is displayed.
5. Set the sensor hand control cursor switch to the up
position (Figure 20-36).
6. Selectt he half-action mode by depressingt he trigger
on the RIO sensor hand control to the first
detent position.
7. Using the RIO sensor hand control, place the DD
cursor over the radar targeta nd depresst he trigger
to the second detent position (full action).
8. Depress the RDR pushbutton on the SURFACE
WPT POS format to display the waypoint latitude
and longitude and box the RDR legend.
9. Ifthe coordinatesa ppearr easonablep, resst he ENTER
pushbutton to place the surface waypoint coordinates
into the proper waypoint file; they can
be verified by selecting the WPT DATA format,

20.3.6.4.4 HUD/Designate Mode. Using the HUD/
designatem ode, the pilot usest he HUD cursor to designate
a visual target and the target position is computed
using aircraft present position and azimuth/elevation
measuredfr om the HUD centert o the designatedt arget.
1. Call up the INS UPDATE format (Figure 20-29).
2. Depress the SWP pushbutton to display the SURFACE
WPT POS format and box the SWP legend.
3. Depress the up or down arrow pushbutton until the
desired waypoint number is displayed.
4. Using the pilot cursor control switch (Figure 20-36),
place the HUD cursor over the visual target and
depress the switch to designate the waypoint.
5. Depress the HUD pushbutton on the SURFACE
WPT POS format to display waypoint latitude and
longitude and box the HUD legend.
6. If the coordinatesa ppearr easonable,d epressE NTER

20.3.6.4.5 DEU Mode. In the DEU mode, the position
of a new waypoint is computed based on its range
and bearing from an existing waypoint already in the
waypoint file. The range and bearing values are entered
