I think this is one of the better discussions on this board. Good points being made on both sides.
crab, I can certainly see where you are generally coming from in this discussion. But I must say the following two paragraphs are completely contradictory:
helipad markings are excellent and, if used correctly, guarantee safe separation from other aircraft so going hard over to remove them would be a retrograde step.
The main issue with this accident was the pilot not recognising that the other aircraft wasn't positioned on the normal spot and adjusting her landing position to cater for it.
The whole point of these markings is that you know the helo will fit in there. You are pointing out that someone didn't use the markings correctly to guarantee safe separation. I agree. But how is this supposed to be the landing pilot as opposed to the one on the ground?
