Shawn; yes, as I wrote earlier in this thread.
Wessex HC2, to get out of a glen in Scotland, to avoid flying backwards for about 2 miles.
Parameters were as earlier stated; IAS 60kts, gnd sp was about 10-15kts backwards. so w/v about 70-75kts. ht about 150ft.(low cloud)
Straight glen, no bends. It was clear-we had just flown up it (very slowly!)
briefed what to expect visually. Came to relative hover (75kts IAS). Turned very very slowly. Allowed d/w drift to accelerate very very quickly. Power came in to maintain ht as came to free air hover going d/w at 75kt g/s. Then accelerated to get a bit of air speed for comfort.
