I'm not sure he may hand over the controls to an unqualified person, except if needed, of course. But always eager to learn something.

In the US, there is no rule prohibiting that action. It is legal. If
there is an accident, there is always the universal "careless and
reckless" clause, but its use does not imply that =all= cases of turning
over the contorls would be careless and reckless. Only that this
particular (hypothetical) case, which =did= result in a crash, was.

One can clearly be careful and prudent when handing over the controls,
and one can be careless and reckless. This is true of any action.
