Abstract
A flight management system of the present disclosure has an internal network that uses an open architecture concept with no single point of failure of critical system and which is cyber secure for aviation assets. A flight management system of the present disclosure comprises an internal network operating on an aircraft, and the internal network communicatively coupled to an external network via a firewall. The flight management system further has a primary system installed on the aircraft, which is initially active, and the primary system has a first weapons domain communicatively coupled to the internal network, a first flight domain communicatively coupled to the internal network, and a first communications domain communicatively coupled to the internal network. The flight management system also has a mirror system installed on the aircraft, which is initially inactive, and the mirror system has a second weapons domain communicatively coupled to the internal network, a second flight domain communicatively coupled to the internal network, and a second communications domain communicatively coupled to the internal network. Furthermore, the flight management system has a monitoring system separate from the primary system and the mirror system and communicatively coupled to the internal network, and the monitoring system has a processor. The processor monitors, over the internal network, the first weapons domain, the first flight domain, and the first communications domain while active. The processor reboots, over the internal network, the first weapons domain, the first flight domain, or the first communications domain if the first weapons domain, the first flight domain, or the first communications domain change state and the processor activates the second weapons domain if the first weapons domain is rebooted, activates the second flight domain if the first flight domain is rebooted, or activates the second communications domain if the first communication domain is rebooted.
