I'm not talking about the BRS, I mean the "Safe Return Emergency Autoland" - big red button the passenger can push if something happens to the pilot.
Apparently it takes into account nearby terrain, weather, remaining fuel, winds etc to calculate the nearest suitable airport and runway. Squawks 7700 and advises ATC of the situation with text messages. Flies the plane down to landing and to a full stop. All without the passenger touching the controls.
There was an article about the Vision Jet G2+ in the latest Australian Flying magazine which went through its capabilities.
