Figure 7: WAYPOINT DISPLAY PAGE
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 param-
eters 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).
Selecting a data option enables the scratchpad on the MFD and HUD; other data options are blanked
(Figure 8). New data is entered with the push buttons on the data entry panel (DEP). When the ENT
push button on the DEP is pressed, the scratchpad is removed, waypoint data is updated with the
new value, the option is unboxed, and the other blanked options are redisplayed. (Note: waypoint
elevation is only used for CCIP bombing computations when using barometric altitude ranging vice
radar altitude ranging; not for waypoint steering or time-to-go.)
