Shawn,
Good evening,
The Ex Raf, and now Cfi/examiner who spent quite a lot of time explaining and actually demonstarting this VRS state to me on one of my annual's headed the Heli into wind, brought the heli to a high hover and when there slowly started to shed power by pushing the leaver down very slowly, we felt the entry into VRS by the vibrations and uncontrolled yaws, at this stage the power was slowly reintroduced and we could see the huge/fast loss of altitude, it was recovered as you have stated by pushing the nose down at the same time as pushing down on the collective and after the airspeed built up to around 15 Knts the power was reapplied and we flew out of this VRS state, but to reiterate we started by flying and hovering into wind, frighteningly it seemed to me the only ref to loss of many hundereds of feet could really only be judged by the instruments, until we were flying again.
