A flight information communication system has a plurality of RF direct
sequence spread spectrum ground data links that link respective
aircraft-resident subsystems, in each of which a copy of its flight
performance data is stored, with airport-located subsystems. The
airport-located subsystems are coupled by way communication paths, such
as land line telephone links, to a remote flight operations control
center. At the flight operations control center, flight performance data
downlinked from plural aircraft parked at different airports is analyzed.
In addition, the flight control center may be employed to direct the
uploading of in-flight data files, such as audio, video and navigation
files from the airport-located subsystems to the aircraft.
