The first fifteen waypoints in the mission data loader are displayed at the top of the screen in the GPS
waypoint identifiers block. The waypoints are in alphabetical order by column. The desired page of the
GPS waypoint identifiers is selected with the increment/decrement arrows in the upper right of the display.
Individual GPS waypoint information is selected by locating the selector box around the desired GPS
waypoint with the selector box control arrows in the upper left corner of the display. The selected GPS
waypoint data is shown in the selected GPS Waypoint Data Block. Using the increment/decrement
arrows on the right side of the display, select the tactical waypoint you want to overwrite; the tactical
waypoint data is shown in the Tactical Waypoint Data Block. Press the push-button next to XFER to copy
the waypoint data from the GPS mission data block into the Tactical Waypoint Data Block. Verification of
a successful transfer of waypoint information is accomplished by comparing the two waypoint data blocks.
They should be the same.
If the navigation aid is not one of the 200 waypoints in the MDL, you can manually enter the latitude,
longitude, and magnetic variation for the navigation aid. To do this, select DATA from the HSI, ADI, or
MENU. Then select WYPT if required (Figure 26). Manual waypoint data entry starts by selecting the
desired waypoint number with the increment/decrement arrows on the right of the display. When the
desired waypoint is displayed, all parameters for that waypoint may then be changed by selecting data
options at the top of the display: LAT (latitude), LONG (longitude), ELEV (elevation), or MVAR (magnetic
variation).
