I would be interested to know how many noise complaints come from this person and his neighbours - I suspect quite a lot - and I'm sure they will have been told that the helicopters are performing vital lifesaving duties and they should just suck it up.
So it comes as no surprise if they try to use this 'devastation' to either gain financial recompense or try to force the MCA/NHS to use a different landing site - right up until one of their friends or family needs urgent transport to A&E.
I am not up to speed with CAP 999 but do they have to use PC1 profiles when they only have the crew on board? ISTR it used to talk about that not being required until the departure from the rescue scene (ie with cas on board) but I haven't operated to it so I could well be mistaken.
