Been thinking that it is probably possible to construct a simple analogy for this, though I haven't put any real thought into it.
It involves the idea that, in aerodynamics, it doesn't matter if the aircraft is moving through the air or the air is moving past the aircraft.
Anyway, it involves a large stationary cube of air with a solid floor (the ground) and a solid ceiling.
The floor is moving from (say) left to right and the ceiling is moving from right to left, both at the same speed WRT the air cube.. This being the equivalent of equal speed winds blowing in opposite directions.
Place an aircraft in the stationary air cube, in a constant turn at a fixed bank angle and CAS.
So according to the turning myth, with reference to both the floor and the ceiling, the aircraft is turning both upwind and downwind simultaneously, and according to the theory of the myth it would be both accelerating and decelerating simultaneously.
This cannot possibly be correct.
But as I said I have put no real thought into this.
