1. A method of ensuring secure and cost effective communication of aeronautical data to and from an aircraft, the method comprising:
- uplinking air-ground aircraft data communications via an aeronautical safety data link, wherein the aeronautical safety data link is a communications link licensed and/or regulated to exchange safety/security data between the aircraft and at least one of a mobile system and a fixed system;
implementing downlink routing protocols to output the safety/security data from a closed domain of the aircraft through a one-way firewall and through at least one of a private domain of the aircraft and a public domain of the aircraft; and
downlinking air-ground aircraft data communications, including the safety/security data, from the respective at least one of the private domain of the aircraft and the public domain of the aircraft to a ground system via a consumer data link separated from the aeronautical safety data link by the one-way firewall.

11. An aeronautical communication system comprising:
-
an avionics communications management function; and a one-way firewall, wherein the avionics communications management function is executable by a processor configured to execute downlink routing protocols to send safety/security data from a closed domain of an aircraft, through a one-way firewall and through at least one of a private domain of the aircraft and a public domain of the aircraft, to ground systems via a consumer data link, the avionics communications management function further configured to execute uplinking routing protocols to receive safety/security data at the closed domain via an aeronautical safety data link, wherein the aeronautical safety data link is a communications link licensed and/or regulated to exchange the safety/security data between the aircraft and at least one of a mobile system and a fixed system, and wherein the one-way firewall is communicatively coupled to pass the safety/security data output from the closed domain, and the one-way firewall is configured to prevent data from entering the closed domain when the data is at least one of uplinked on the consumer data link to the private domain, and uplinked on the consumer data link to the public domain. - View Dependent Claims (12, 13, 14, 15)

16. An aeronautical communication system comprising:
-
ground systems, wherein the ground systems include; a consumer data link router configured to receive via a consumer data link the safety/security data output from a closed domain in an aircraft via the consumer data link; a ground communications peer communicatively coupled to the consumer data link router, the ground communications peer configured to send consumer data to at least one of a private domain in the aircraft and a public domain in the aircraft via the consumer data link; and an aeronautical safety data link router communicatively coupled to the ground communications peer, the aeronautical safety data link router configured to send safety/security data to an avionics communications management function in the closed domain of the aircraft via an aeronautical safety data link, wherein the aeronautical safety data link is a communications link licensed and/or regulated to exchange the safety/security data between the aircraft and at least one of a mobile system and a fixed system; and at least one processor to execute software in the consumer data link router, the ground communications peer, and the aeronautical safety data link router. - View Dependent Claims (17, 18, 19)

20. A system to ensure secure and cost effective communication of aeronautical data to and from an aircraft, the system comprising:
-
means for uplinking air-ground aircraft data communications, wherein the means for uplinking is licensed and/or regulated to exchange safety/security data between the aircraft and at least one of a mobile system and a fixed system; means for implementing downlink routing protocols to output the safety/security data from a closed domain of the aircraft through a one-way firewall and through at least one of a private domain of the aircraft and a public domain of the aircraft; and means for downlinking air-ground aircraft data communications, including the safety/security data, from the respective at least one of the private domain of the aircraft and the public domain of the aircraft to a ground system, the means for downlinking air-ground aircraft data communications being separated from the means for uplinking air-ground aircraft data communications by the one-way firewall. - View Dependent Claims (21, 22, 23, 24)
