I think we are still being confused here - to recap - conditions for entry into IVR are 1. low KIAS < 20, 2. ROD > 200ft/min, 3. increasing power from minimum to a lot. What happens next? Witrh collective still under your armpit ROD rapidly increases to in excess of 5000 feet plus, airframe vibration, random yawing. What is happening aerodynamically? Outboard section of blade not producing lift due to ingested vortices increasing induced flow reducing angle of attack, inboard section exceeding stalling angle of attack, decreasing middle section producing insufficient lift. Recovery action - lower lever - yes entering auto even - forward cyclic to "blow" vortices "back" to prevent ingestion. Need lots of AGL. Lesson? Recognise conditions of flight required to reach IVR and take corrective action before fully developed VR is encounted.
Had this discussion with a VERY experienced mate yesterday and it was clear to me that he did not understand the regimes of flight that put him in the danger zone!
