At the risk of being shot down (or even entering irecoverable VRS!) could someone explain what difference being downwind will have when conducting this demonstration (IVRS) at a suitable altitude?
I fully understand the significance of being downwind close to the ground and allowing IAS to decay due to external cues, but surely if at N thousand ft plus,, and using the IAS as a reference for the entry conditions there should be no relevance to the wind direction?
Not wishing to get into a 'downwind turn' debate!
