Flying the ILS with cyclic in Oz also has another ramification: and adjustment of 10 kias, or 10% which ever is less, shall be notified to ATC. Also, I wonder what the efeects on preceeding/following traffic would be, but I suspect it is minimal given seperation standards.
Collective Bias, I suspect your comment of most Bell pilots flying the cyclic could be reworded, as I find it is most Jetranger pilots - but not Huey pilots. They tend to get in the habit of setting top of the green and flying altitude with cyclic in the cruise, whereas in the Hueys (except 412), doing this would result in a significant VNE exceedance. Given alot of guys have flown jetranger first, it is a habit that needs to be sorted out in the huey transition.
