Abstract

A method and system for an aircraft communications system. The aircraft communications system comprises an Internet protocol network router and an aircraft communications addressing and reporting system network router. The Internet protocol network router, located within an aircraft, is configured to transmit data to a group of ground stations remote to the aircraft using an Internet protocol communications link. The aircraft communications addressing and reporting system network router, located within the aircraft, is connected to the Internet protocol network router. The aircraft communications addressing and reporting system network router is configured to transmit the data from aircraft systems to the group of ground stations using at least one of an aircraft communications addressing and reporting system communications link or, via the Internet protocol network router, using at least one of an Internet protocol communications link.
