I've just seen this post,

Little chance of the inflation of a G-suit, or G-force alone, causing
unintentional operation in that case. (I don't know if this applied to
specifically to the Gripen.)
With aerodynamically unstable aircraft, the situation is different. If the
FCS goes down, the aircraft might break up within half a second or so,
depending on the airspeed and attitude, and I was given to understand that
ejection would be automatic, i.e., initiated without manual input from the
pilot.
Is it true that the ejector seat fire if the system thinks the air craft is a lost cause?
