If (big IF) you have some aviation background and basic a/c handling skills (not FS) you might just be lucky enough to bring a single engined light a/c in. But if a PPL or FS "expert" thinks they could land a widebody airliner, FORGET IT!
Really?
I have 10000 hours (probably) on FS. I have the 747-400 professional add-on. 95 page FMC manual for the fully functional FMC. Plus the overhead panel is fully functional and comes with a massive f-off manaul.
I'm also doing a PPL. When I was lucky enough (via friend of a friend ad infinitum)to be given a chance to land a 744 in a sim , guess what the landing was near perfect (a/p off at 1250ft localiser and GS established)- a far cry from when I first tried to land a 152 during my PPL.
"these things almost land themselves" could never be more true
