wizzard, good idea...
So I went out to do a limiting check today, and tried HOV out for a few while over the threshold of the runway in 10Kt winds.
I noticed little difference. Engaging COLL driving made us go up and down a few feet while in a 5-10 foot hover....good for a laugh.
My final thoughts? It certainly didn't make thinks worse laterally, but I did not notice much improvement. I wouldn't use the collective driving/RAD alt. mode too low....
I was hoping it would smooth out some of the lateral dancing the A/C likes to do in the wind as air swirls over the tail rotor...no luck there.
