It's certainly easier to teach that the sun revolves around the earth (fits the brain of the student), but the truth is the reverse and the brain must be molded to understand it.

(Doesn't "centrifugal force" still appear in some FAA texts?)
Yes, but I believe that they acknowledge that it's a fictitious force. And I think the force vector was removed from the diagram in the latest version of the Airplane Flying Hanbook.

But "it's not on the checkride" is hardly a valid criticism.
That wasn't meant to be a criticism, per se, but just an implication that the explanation was fundamentally screwed up (to use a technical term) and even an FAA examiner should realize it.

Radical concept, but I think a flight instructor must have some inkling of how airplanes fly.
