1. A method of ensuring secure 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 at least one of;
a communications link licensed to exchange safety/security data between the aircraft and at least one of a mobile system and a fixed system;
or a communications link regulated to exchange the safety/security data between the aircraft and at least one of the mobile system and the fixed system; and
determining which of at least two data links to use for downlinks of the safety/security data based on at least one of;
a type of message to be downlinked; and
a size of message to be downlinked, the at least two data links including the aeronautical safety data link and at least one consumer data link, wherein the at least one consumer data link is separated from the aeronautical safety data link by a one-way firewall.

10. A method of ensuring secure communication of aeronautical data to and from an aircraft, the method comprising:
-
uplinking air-ground aircraft data communications via an aeronautical safety data link to a closed domain of the aircraft, wherein the aeronautical safety data link is at least one of;
a communications link licensed to exchange safety/security data between the aircraft and at least one of a mobile system and a fixed system;
or a communications link regulated to exchange the safety/security data between the aircraft and at least one of the mobile system and the fixed system;implementing downlink routing protocols to unidirectionally output the safety/security data from the closed domain of the aircraft through a one-way firewall; downlinking air-ground aircraft data communications via at least one consumer data link separated from the aeronautical safety data link by the one-way firewall; and uplinking message acknowledgements of the safety/security data received at the at least one of the mobile system and the fixed system from the closed domain of the aircraft, the uplinked message acknowledgements being uplinked via the aeronautical safety data link using an aviation industry standard-based protocol. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
