When should the thrust be set by though? I thought it was 60knots, in which case it is often necessary to intervene as the AT second stage is sometimes too slow to reach target by this speed. A couple of times I've still been waiting for the thrust to set when we've reached 80knots - and in my company we are supposed to have "thrust set" before we call "80 knots".
