I’ve given my wife the basic heading, airspeed, trim, radio comms briefing and experience. (And also given my older kid the same experience but just for fun.)
If I kicked off in flight on day/good weather, and she was up front, I’m pretty sure that airplane would end up inside the airport perimeter, probably stopped on all three wheels on a runway. That’s not to take anything away from this pax feat, but it’s pretty likely they at least had a pretty good idea of how things work. (And were in a fairly simple airplane.)
The handful of times I've been up with private pilots who took me in their cessna, I did get an if I become incapacitated speech where they showed me how to operate the radios how to squawk 7700 and how to keep the plane level before we even took off.
