Why not just call it recirculation?. .. .The asymmVR characteristic of the Osprey is the same phenomenon but a wholly different problem - because the instinctive application of differential collective (opposite aileron if you will - for to pick up that dropping wing) is just what induces even greater "recirculation" and so a more rapid roll results. The end game is suddenly a flick-roll with nose pitching down - as at Marana. Some have likened it to the FW's autorotational spin entry (which is a stall exacerbated into an incipient spin by use of opposite aileron in an attempt to pick up a "dropped" wing).. .. .In addition, the V-22's ability to rotate the nacelle's to 95 degrees makes it even easier to point your downwash in a projection right down along your flight-path.... greatly facilitating recirculation. When is a pilot likely to utilise that 95 deg capability? Just like in Marana when you've misjudged slightly (i.e. overcooked your rejoin).
