Gordy - absolute rubbish! You can't demonstrate Incipient VRS without allowing it to show the pilot all the feedback effects [Which I hope we all are aware of].
This will cost atleast 500-1000' height loss! Slowing down inaccurately in preparation for the demo could cost you 100', never mind recovering before this amount of height loss
Your poor customers are going away thinking a slight judder and they are in IVRS!!!
Coyote: As an ex mil instructor and currently sim instructor on heavies, I agree with your observations.
What people dont hoist in is that during fully developed VRS the a/c is: OUT OF CONTROL. The pilot cannot take charge of the a/c. It will either crash or fly itself out of the state. The problem with the latter is that it could take thousands and thousnads of feet for it to allow you to regain control.
make NO mistake here. Fully developed VRS is UNCONTROLLABLE!
What happens in real life with these 'instructors' is that they actually demonstrate IVRS and not VRS.
People who search for the real McCoy especially at entry gates of 4000' and below are living on borrowed time IMO.
