That which is claimed is: 1. A method of transmitting aircraft data comprising: acquiring data within a memory of a PC card comprising a PC card body having a PCMCIA form factor and that is interfaced with an aircraft component; retrieving the aircraft data from the memory based on commands receive
That which is claimed is: 1. A method of transmitting aircraft data comprising: acquiring data within a memory of a PC card comprising a PC card body having a PCMCIA form factor and that is interfaced with an aircraft component; retrieving the aircraft data from the memory based on commands received from a processor contained within the PC card; and transmitting the retrieved aircraft data from a transmitter contained within the PC card along a radio frequency signal and passively coupling RF energy into the skin of the aircraft, which is operative as a passive radiator to re-radiate the radio frequency communications signal to a location remote from the aircraft such that the RF communications signal is transmitted without use of a separate antenna mounted on the aircraft. 2. A method according to claim 1, which further comprises interfacing the PC card to the aircraft component using a PCMCIA slot. 3. A method according to claim 1, wherein the aircraft data comprises flight performance data. 4. A method according to claim 1, wherein the aircraft data comprises aircraft engine data. 5. A method according to claim 1, wherein the aircraft data comprises in-flight entertainment data. 6. A method according to claim 1, wherein the aircraft data is related to at least one of aircraft contents, passenger data, aircraft departure and arrival, passenger transactions, or data from a sky marshall. 7. A method according to claim 1, which further comprises collecting aircraft data from a Data Acquisition Unit (DAU). 8. A method according to claim 1, which further comprises transmitting the aircraft data over a spread spectrum communications signal. 9. A method according to claim 8, which further comprises transmitting the aircraft data over a frequency hopping spread spectrum communications signal. 10. A method according to claim 8, which further comprises transmitting the aircraft data over a direct sequence spread spectrum communications signal. 11. A method according to claim 1, which further comprises transmitting the aircraft data to a Central Maintenance Display Unit (CMDU) indicating in real-time the health and status of aircraft systems. 12. A PC card that interfaces with an aircraft component for transmitting aircraft data received from the aircraft component comprising: a PC card body having a PCMCIA form factor; a PC card interface adapted for connecting to an aircraft component; a memory for storing aircraft data received from the aircraft component; a radio transmitter for receiving aircraft data from the memory and transmitting the aircraft data over a radio frequency signal and passively coupling RF energy into the skin of the aircraft, which is operative as a passive radiator to re-radiate the radio frequency communications signal to a location remote from the aircraft such that the RF communications signal is transmitted without use of a separate antenna mounted on the aircraft; a processor operatively connected to the PC card interface, memory and radio transmitter for reading and forwarding data from memory to the radio transmitter; and a logic circuit operative with the memory, processor and PC card interface for controlling the downloading of data from the aircraft component to the memory and the reading and forwarding of data from the memory to the radio transmitter without conflict between the processor and aircraft component. 13. A PC card according to claim 12, wherein said logic circuit comprises a field programmable gate array. 14. A PC card according to claim 12, wherein said transmitter comprises a spread spectrum transmitter for transmitting aircraft data over a spread spectrum communications signal. 15. A PC card according to claim 14, wherein said transmitter is operative for transmitting said spread spectrum communications signal over a frequency hopping spread spectrum communications signal. 16. A PC card according to claim 14, wherein said transmitter is operative for transmitting said spread spectrum communications signal over a direct sequence spread spectrum communications signal. 17. A PC card that interfaces with an aircraft component for transmitting aircraft data received from the aircraft component comprising: a PC card body having a PCMCIA form factor; a PC card interface adapted for connecting to the aircraft component; a memory for storing aircraft data received from the aircraft component; a radio transceiver for receiving aircraft data from the memory and transmitting the aircraft data over a radio frequency communications signal and passively coupling RF energy into the skin of the aircraft, which is operative as a passive radiator and to re-radiate the radio frequency communications signal to a location remote from the aircraft such that the RF communications signal is transmitted without use of a separate antenna mounted on the aircraft, and receiving data over a radio frequency communications signal for onboard processing; a processor operatively connected to the PC card interface, memory and radio transmitter for reading and forwarding data from memory to the radio transmitter and controlling receipt of data for onboard processing; and a logic circuit operative with the memory, processor and PC card interface to aid in controlling the downloading of data from the aircraft component to the memory, and the reading and forwarding of data from the memory to the radio transmitter without conflict between the processor and aircraft component. 18. A PC card according to claim 17, wherein said logic circuit comprises a field programmable gate array. 19. A PC card according to claim 17, wherein said transceiver comprises a spread spectrum transceiver for transmitting and receiving data over a spread spectrum communications signal. 20. A PC card according to claim 19, wherein said transceiver is operative for transmitting and receiving said spread spectrum communications signal over a frequency hopping spread spectrum communications signal. 21. A PC card according to claim 20, wherein said transceiver is operative for transmitting and receiving said spread spectrum communications signal over a direct sequence spread spectrum communications signal. 22. A PC card according to claim 17, wherein said transceiver is operative for receiving data for transfer to an aircraft component via the PC card interface. 23. A PC card according to claim 17, wherein said transceiver is operative for receiving and transmitting the data using the radio transmitter.
