You try and take velocity from one frame and claim it effects the aircraft in another.
You can't do that.
You should probably realize that when the guy with whom you're discussing the physics of a turning airplane says that the principles of physics don't apply because it's "meteorology", any chance of in intelligent conversation has completely vanished.

Exactly, you may as well beat your head against the wall debating with a Flat Earther or a Chemtrail believer. All these type possess a defect in their reasoning. It doesn't matter how rationally you explain his errors, there will always be some irrational defense mechanism which kicks in to avoid seeing reality. In this case, Brercrow has pretty conclusively demonstrated that he's a member of that club by claiming that the principles of physics don't apply to a discussion of the motion of an airplane.
