Yes agreed - My figures are really just about UK Offshore work.
If you look just last year there were two accidents in the Arabian Gulf, one a 212, the other a AB139, both at night (OK, some unusual circumstances for one, but the other, an experienced pilot trying to take off from a typical deck at night and I believe (although I haven't read an official report) drifting backwards clipping the tail.
Then there is the EMS world in America which is just reviewing ops at night following a whole string of accidents, and under pressure from Insurance companies (amongst others), who have had to make such a ridiculous amount of pay-outs. I accept Night EMS is not the same as offshore night.
My only point is, there is a problem here - Little doubt of that. The question is, can we resolve this issue with training, legislation and equipment ? Following Morecombe Bay, I think some would have argued yes, but Etap was a well trained crew, in the very latest aircraft, to one of the largest platforms in the North Sea, with the very best deck lighting.
You draw your own conclusions ............
