The disc can't flap to equality when the cyclic position prevents it from doing so. Doesn't mean it isn't trying to.

Agreed, the sudden increase in ROD is a fair indicator of VRS on a downwind approach.

Don’t they teach people how to get from downwind to into wind whilst maintaining ETL any more?
