Epiphany
I also spent 15 yrs flying with a mk4A. Then an Alpha with the plod. I am now on the SNS and would not be able to offer 1 reason as to why a helmet wouldn't benefit.
Nothing worse than having to break the seal of a crap peltor headset, when flying a 76c, to don a pair of sun glasses. To exacerbate what is already inadequate hearing protection. No need with a helmet that would have a dark visor, Cost less than £1000 with ANR, weighs less than 900g and would offer some practical visibility if you were unlucky enough to be floating alone in the North sea, while wearing the current emmersion suit issued to aircrew on the North Sea.
