PC Flight sims and real planes

In the rather clichéd movie scenario of the pilot and copilot both becoming unable to operate a plane that is in level flight (say it’s on autopilot), is the idea of an experienced pilot on the ground ‘talking them down’ in any way possible?

Would it be a help or a hindrance if the person in the cockpit had extensive experience of a wide range of amateur (PC) flight simulations?

Oops, i see this is already being discussed in another thread: How hard is it to fly a plane?.

Sorry
