I'm not a pilot. I've had one introductory lesson (no take off or landing, but approach) and spent many hours on Flight Simulator. But additionally I've been handed the controls quite a few times (various small Cessnas and an Islander). My friend who took me up in the Cessnas would involve me in all aspects, from basic checks prior to getting in the plane, changing frequencies, throttle/pitch control, flaps, flight maps/navigation etc. And of course I would pick up the radio terms. I don't think back in those days I would have had any problem maintaining flight, checking instruments and talking to someone on the radio. And whilst I would have been nervous I would hope that I could have got us onto the ground under guidance. With some basic knowledge it's not that hard if condtions are good and the aircraft is operating normally.
