Figure 2: 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 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).
Selecting a data option enables the scratchpad on the MFD and HUD; other data options are blanked
(Figure 3). New data is entered with the pushbuttons on the Data Entry Panel (DEP). When the ENT
pushbutton 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.)
