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.
