To add to 'squib66s' comments.
The EC225 and S92 both have floation system which are certified up to 6m waves. The sea state in parts of the CNS today were as follows:
Goldeneye Sig Wave 7.0m Max Wave 10.2m
Forties A Sig Wave 6.9m Max Wave 11.0m
Unity Sig Wave 6.8m Max Wave 11.9m
Nelson Sig Wave 6.7m Max Wave 9.9m
ETAP Sig Wave 5.8m Max Wave 10.5m
I could go on, but I think you get the picture. The trials on launching FRCs (fast rescue craft) show that 5.5m seas are the limit. Anything over 5.5m means that the only method of recovery is the DACON Scoop. BALPA policy is that commercial flights should not depart if the primary method of recovery is the scoop. I say BALPA policy, but it is really common sense! UK Oil and Gas did release a piece of video showing the trials of the scoop done in 2009, in very gentle sea states. Having watched the video evidence, I don't want to get anywhere near a DACON Scoop!
So, if you were a passenger waiting for a flight today which didn't materialise, then it was probably because the crew were using their common sense! North Sea pilots want to go home at nights just like everyone else - they will not take un-neccessary risks. If it is safe to fly, they will do so. If not, they won't!
