Patent ID: 7428412

Claim:
A method of providing data from an aircraft comprising: continuously monitoring the flight performance of the aircraft during an entire flight of the aircraft from at least take-off to landing; generating aircraft data representative of the continuously monitored aircraft flight performance during an entire flight of the aircraft from at least take-off to landing; accumulating and continuously storing the generated aircraft data within a ground data link unit positioned within the aircraft during the entire flight of the aircraft from at least take-off to landing to create an archival store of such aircraft data; after the aircraft completes its flight and lands at an airport, transmitting the accumulated, stored generated aircraft data from the ground data link unit over a RF communications signal operating in a channel of a frequency spectrum band which has been sub-divided into adjacent sub-band channels to a ground based RF receiver; and demodulating the received RF communications signal to obtain the accumulated, aircraft data representative of the flight performance of the aircraft during an entire flight of the aircraft from take-off to landing.
