Here we go again - or rather.....no we don't. I'm not going to waste any more time on VRS, SWP et al.
Suffice to say once and for all, the following:
IVRS is identified by buffeting, vibration and unintended height loss under power.
Atleast several hundred feet will be lost before any half awake pilot will identify they are in IVRS.
Once they initiate recovery using normal or VR technique, atleast 1 or 2 hundred feet will be lost. Overall - no-one here has ever recovered from IVRS in less than 2 or even 300 feet. If you have - you did not enter IVRS.
If you find yourself in FDVRS, then goodbye several thousand feet height loss - minimum, while you battle to regain full response from the cyclic/collective (Yaw not normally affected).
Don't ever convince yourself that any of these aerodynamic phenomena will only lose you 50 - 100 - 150 feet. You're in la la land sunshine.
Bye di bye....................
