As we have discussed before John, the Collective Acceleration Control (CAC) activated at around 2G (we used to demonstrate it in a 60 deg AoB turn) and it took off collective pitch equivalent to about 15% Tq. You added more collective to maintain the turn but had to be careful to lower the lever again as you rolled out and reduced the G loading or you could overtorque.
I was told by the old and bold that it was designed in to the aircraft to try and reduce the severity of a pitch lane runaway.
