What is claimed is: 1. A method of sending a message from an air borne aircraft, comprising: composing a message on a PDA device; transmitting the message from the PDA device over an aircraft cabin wireless network to a communications management unit (CMU); encrypting the message to create an encrypted message; sending the encrypted message via an ACARS network; receiving the encrypted message at a datalink service provider; forwarding the encrypted message to an operations center; and decrypting the encrypted message to obtain the message. 2. The method of claim 1, wherein the step of composing a message comprises using predefined message structures. 3. The method of claim 1, wherein the wireless network is based on a protected IEEE 802.11 (b) protocol. 4. The method of claim 1, wherein the step of encrypting is performed by the CMU. 5. The method of claim 1, wherein the message is displayed for the flight deck personnel. 6. The method of claim 1, further comprising communicating with other PDA devices on the same aircraft. 7. The method of claim 1, further comprising sending a message from the operations center to a PDA device in an airborne aircraft. 8. A method of sending a message from an air borne aircraft, comprising: composing a message on a PDA device; encrypting the message to create an encrypted message; transmitting the encrypted message from the PDA device over an aircraft cabin wireless network to a communications management unit (CMU); sending the encrypted message via an ACARS network; receiving the encrypted message at a datalink service provider; forwarding the encrypted message to an operations center; and decrypting the encrypted message to obtain the message. 9. The method of claim 8, wherein the step of composing a message comprises using predefined message structures. 10. The method of claim 8, wherein the wireless network is based on an IEEE 802.11(b) protocol. 11. The method of claim 8, wherein the step of encrypting is performed by the PDA. 12. The method of claim 8, further comprising communicating with other PDA devices on the same aircraft. 13. The method of claim 8, further comprising sending a message from the operations center to a PDA device in an airborne aircraft. 14. A system of sending a message from an air borne aircraft, the system comprising: a means for composing a message on a PDA device; a means for transmitting the message from the PDA device over an aircraft cabin wireless network to a communications management unit (CMU); a means for encrypting the message to create an encrypted message; a means for sending the encrypted message via an ACARS network; a means for receiving the encrypted message at a datalink service provider; a means for forwarding the encrypted message to an operations center; and a means for decrypting the encrypted message to obtain the message. 15. The system of claim 14, wherein the means for composing a message comprises a means for using predefined message structures. 16. The system of claim 14, wherein the wireless network is based on a protected IEEE 802.11(b) protocol. 17. The system of claim 14, wherein the means for encrypting is performed by the CMU. 18. The system of claim 14, wherein the message is displayed for the flight deck personnel. 19. The system of claim 14, further comprising a means for communicating with other PDA devices on the same aircraft. 20. The system of claim 14, further comprising a means for sending a message from the operations center to a PDA device in an airborne aircraft. 21. A system of sending a message from an air borne aircraft, comprising: a means for composing a message on a PDA device; a means for encrypting the message to create an encrypted message; a means for transmitting the encrypted message from the PDA device over an aircraft cabin wireless network to a communications management unit (CMU); a means for sending the encrypted message via an ACARS network; a means for receiving the encrypted message at a datalink service provider; a means for forwarding the encrypted message to an operations center; and a means for decrypting the encrypted message to obtain the message. 22. The system of claim 21, wherein the means for composing a message comprises a means for using predefined message structures. 23. The system of claim 21, wherein the wireless network is based on an IEEE 802.11(b) protocol. 24. The system of claim 21, wherein the means for encrypting is performed by the PDA. 25. The system of claim 21, further comprising a means for communicating with other PDA devices on the same aircraft. 26. The system of claim 21, further comprising a means for sending a message from the operations center to a PDA device in an airborne aircraft.
