To follow on from Notso's point, I haven't seen anyone here say you must ALWAYS follow SOPs. If I were on final approach after everything had gone wrong, one engine out, no hydraulics, no electrics, fuel down to 100 kgs, rubber jungle hanging out down the back and my wife going into labour, I don't think an EGPWS warning in VMC would make ME go around...
But if you do, you'd better be darned sure you're right, and it had better be a provable life-saver to do so. The Emerald HS748 @ STN was a case in point. The skipper went against all training there - and he was right to do so.
