Abstract: This electronic communication gateway is intended to be placed on board an aircraft, and is configured to communicate with an external electronic system, positioned outside the aircraft, said information being exchanged in the form of radio waves between the external system and the aircraft; the electronic communication gateway includes an acquisition module configured to acquire information from the external system, and a transmission module configured to transmit the acquired information to an avionics system on board the aircraft; the acquisition module is configured to acquire, from the external system, a current date upon powering on the gateway, and the transmission module is configured to send the acquired current date to the avionics system, for the initialization of the avionics system.

Abstract: This system ensures autonomous protection of an aircraft against deliberate crashes resulting from a malicious act of a person on board or a trajectory error. It comprises a prohibited zone anti-penetration (cons. anti-collision) rig OAPS (54) operating in the manner of a terrain anti-collision rig TAWS (51) but intervening at the level of the flight controls (12) so as to impose an avoidance trajectory on the aircraft (83) when the need therefor is felt. This prohibited zone anti-penetration (cons. anti-collision) rig OAPS (54) uses a database (60) holding information about the prohibited zones and a system for positioning (106, 306) of the aircraft (83). Supplemented with a terrain anti-collision rig TAWS (51) and a rig for protection of the limits of the flight domain FELPS (53), it makes it possible to produce a very complete flight protection system.
