A system and method are provided for the efficient entry and display of
ground taxi routes on an electronic airport map display. The system may
include a touchscreen entry device, a display device, a computer, a map
database, a vehicle position sensor and a transmitter/receiver. The
system may be configured to check the ground taxi entries to ensure that
each successive segment is contiguous with the last or next segment, and
any gaps or discontinuities in the displayed taxi instructions may be
annunciated. An intelligent display of next possible segments may be
incorporated into the system.
