SarOwl - I know 2 that came from the RAF and became senior trainers with CHC - they aren't there now but I suspect it is their legacy that night wets are completed.
The present incumbents may be ex-RN but perhaps they were educated into the ways of the light-blue
Jim, the fact that both the S92 and AW189 have rear crew stations with moving map/FLIR/TV/radar displays means that they most certainly are involved very heavily in the safety of the aircraft and as such should be licensed and paid appropriately.
