NOTE: If the pilot attempts to modify or delete a
waypoint which is currently a direct-to waypoint
or the current ‘from’ or ‘to’ waypoint in the active
flight plan, the GNS 430 alerts the pilot with the
‘Can’t change an active waypoint’ or ‘Waypoint
is active and can’t be deleted’ message. The
pilot must first cancel the direct-to or remove
the waypoint(s) from the active flight plan before
modifying or deleting the waypoint(s).
