The S-92 "rig approach" goes around automatically if the pilot does not intervene to carry out a landing. The original concept was, if it all starts to go wrong, just let go and the aircraft will perform a GA at the pre determined pilot selected minimum. The original paper resulted from the BLUN accident in 2006. The final approach speed is GS predicated if I remember.
