Question Re: Airspeed

Does the zero lift axis depend on airspeed? I think the article should answer this question. — Preceding unsigned comment added by 24.244.32.56 (talk) 05:48, 22 January 2015‎

In any incompressible flow around an airfoil there is no reason to expect the orientation of the zero-lift axis to vary with different flow speeds. In transonic, sonic and supersonic flows around an airfoil the orientation of the zero-lift axis is likely to vary with Mach number. I haven't looked for a published source for my views.
