Re: Well...
Almost entirely correct! The seat will fire automatically in the event of a lift fan failure, as this just happens too fast for any human to react. The pilots did not like this feature being added at all!
And almost no connections from the aircraft to the seat, as you say, the interface block just passes through signals for the helmet and comms, however, the seat height is passed back to the aircraft, so the system can marry up the head angle with a position and work out where the pilot is looking, for the helmet functionality
