I think it maybe due to the high intensity helo traffic in the area
That surely can't be right? I wouldn't have thought that an aircraft's insurance policy, however huge the sum insured, would cover for accidents happening off the aerodrome/outside the ATZ, and inside the ATZ everyone's under full ATC control so how could lots of heli ops (actually there aren't that many) affect the level of risk?
I haven't looked, but I'm prepared to bet Aberdeen, Scatsta, Humberside and Norwich don't have massive insurance requirements and they have more or as many heli movements as Blackpool.
