A system and method provides a retrievable record of the flight performance of the aircraft and includes a ground data link unit that obtains flight performance data representative of aircraft flight performance during flight of the aircraft. A spread spectrum transceiver is coupled to a data store and operative to download flight performance data that has been accumulated and stored by the data store over a spread spectrum communication signal. A ground base spread spectrum transceiver receives the spread spectrum communication signal from the aircraft and demodulates the signal to obtain flight performance data. A wireless unit is operative with the ground data link unit. This wireless unit could be for inventory control of products during in-flight servicing of passengers.

A method for entering or retrieving data on a aircraft comprising the steps of: storing data relating to the flight performance of an aircraft within a data store of a ground data link unit of the aircraft; and entering or retrieving data related to at least one of aircraft contents, passenger data, aircraft departure and arrival, or passenger transactions within a hand-held unit operable in the aircraft and that communicates with the ground data link unit via a wireless radio integrated with the hand-held unit. 15. A method according to claim 14, and further comprising the step of maintaining inventory control of selected aircraft contents by entering or deleting data using the hand-held unit.16. A method according to claim 14, and further comprising the step of maintaining passenger data using the hand-held unit.17. A method according to claim 14, and further comprising the step of maintaining data relating to aircraft departure and arrival times using the hand-held unit.18. A method for entering or retrieving data on a aircraft comprising the steps of: storing data relating to the flight performance of an aircraft within a data store of a ground data link unit of the aircraft, and downloading and up loading data to and from the ground data link unit over a spread spectrum communications signal; and entering or retrieving data related to at least one of aircraft contents, passenger data, aircraft departure and arrival, or passenger transactions within a hand-held unit operable in the aircraft that communicates with the ground data link unit via a wireless radio integral to the hand-held unit. 19. A method according to claim 18, and further comprising the step of downloading and uploading data over a direct sequence spread spectrum communications signal.20. A method according to claim 18, and further comprising the step of downloading and uploading data over a frequency hopping spread spectrum communications signal.21. A method according to claim 18, and further comprising the step of downloading and uploading data over a chirp modulated spread spectrum communications signal.22. A method according to claim 18, and further comprising the step of downloading and uploading data over a spread spectrum communications signal that is within 900 MHz, 2.4 GHz, and 5.0 GHz spread spectrum communication bands.23. A method according to claim 18, and further comprising the step of downloading and uploading data over a spread spectrum communications signal that is modulated with forward error correction.24. A method according to claim 18, and further comprising the step of maintaining inventory control of selected aircraft contents by entering or deleting data using the hand-held unit.25. A method according to claim 18, and further comprising the step of maintaining passenger data using the hand-held unit.26. A method according to claim 18, and further comprising the step of maintaining data relating to aircraft departure and arrival times using the hand-held unit.
