One point that is rarely considered is that during an autorotation the biggest factor affecting Nr is 'g'. This means that you can, in fact, lower the lever TOO quickly as the trade off between ROD aiorflow and 'g' must be maintained - if you achieve much less than .5 g you are going to have lots more problems so a negative pitch detente is not going to help.. .. .On the subject of regaining Nr at low altitude, ie. to flare or not to flare. If you regain Nr by initially flaring and have at least 30 kts most SE helos can be quite safely landed using the no flare technique (constant attitude to those CFS trained chaps). I have not done this in an R22. .. .GA
