Following up on [this question about pilots letting passengers fly the plane](https://aviation.stackexchange.com/questions/3039/are-pilots-allowed-to-let-passengers-fly-the-plane), suppose you’re in a Cessna 172 with passengers and you have your PPL. If you want to let a friend try flying the plane, you might climb to 3,000' AGL and get clear of other traffic. You’d probably get to $V\_A$ or a little less and trim for level flight. Then, you might let them try some shallow turns. You’d probably say:

* Don’t fight me on the controls
* If I say let go, let go immediately
* Don’t move any of the controls very rapidly
* Don’t move any of the controls to their limits

What else might you say? Are these things correct? What else might you let them try?
