What momentum is being ignored?
From negative 499 to positive 501, that's a thousand knot increase. The airspeed is 1 knot before and after, unchanged.
And *I* don't think that there is anything ignored about the momentum, but the windward turn theorists do (like the one I quoted in my reply) and I'm challenging then to apply their reasoning to that situation.
