EDITING A WAYPOINT
From the FPL tab, the bottom right knob on the AeroNav can be
used to edit an existing waypoint. Using the knob, scroll up or
down the flight plan until an edit cursor surrounds the waypoint to
be modified. Use the inner ring of that knob to highlight one of the
editable fields with reverse video. Pushing the knob provides a
drop down box from which the changes can be made.
Alternatively, touching the field to be edited will display a virtual
keyboard which can be used to enter the desired data/changes.
ADDING ALTITUDE CONSTRAINTS
On virtually every waypoint, you can elect to assign an altitude
constraint (e.g. cross the waypoint at or above a specific altitude,
be at a specific altitude a specified distance prior to the waypoint,
etc). This is accomplished by ensuring an edit cursor surrounds
the waypoint of interest to select the waypoint and then either use
the bottom right inner knob or touch the desired field to highlight
one of the altitude constraint fields of the flight plan leg. Push the
knob and enter the desired value or double tap the field to display
a virtual keypad. This can be accomplished at any time on the
ground or in-air and are depicted on the map display as well.
