1. A system for providing a retrievable record of the flight performance of an aircraft comprising:
- an airborne data acquisition unit coupled to the aircraft flight data recorder that continuously obtains flight performance data representative of aircraft flight performance during an entire flight of the aircraft from at least take-off to landing,a wireless radio frequency (RF) carrier-based subsystem coupled to the airborne data acquisition unit including;
a processing unit that receives and processes the flight performance data collected by the airborne data acquisition unit,an archival data store coupled to the processing unit operative to continuously accumulate and continuously store the processed flight performance data during a flight of the aircraft from at least take-off to landing, anda wireless RF transceiver coupled to said archival data store, and comprising a transmitter that is operative after the aircraft completes its flight and lands at an airport to automatically download the flight performance data that has been accumulated and stored by said archival data store during an entire flight of the aircraft from at least take-off to landing over a wireless RF communication signal;
a ground based receiver that receives the wireless RF communication signal from the aircraft and demodulates the signal to obtain the flight performance data; and
a ground based data store coupled to said ground based receiver that receives and stores said flight performance data.

Abstract
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.
