NR droop or not in OEI CTO
Does anybody know which way has more lift in OEI CTO of FADEC (EEC) helicopter to droop NR at some extent or no droop at all?
The instructor I met in the past said to me that to droop NR to the minimum of OEI NR range if needed below Vtoss gives us more lift results in smaller height loss but after passing Vtoss to recover NR without droop gives us more lift.
I found the article on AOPA HP that the combination of best range speed and minimum continuous NR in autorotation gives us best range due to lift to drag ratio.
Is this true to OEI CTO until Vtoss mentioned above?
