Could you land a plane in an emergency?

That would actually be a pretty interesting experience to conduct using a panel of people with various amount of flying experience ranging from none to being a hardcore flight simulation enthusiast knowing everything about said plane on paper.
I would however allow access to a knowledgable pilot able to guide the test subject over the radio (assuming they figure out how to operate it) as you would certainly get in a real life situation.
That's a bit like driving a car and there's no accelerator pedal and with the steering wheel feeling like a piece of wet string.
