Well, I learned from flight sim that it's a really bad idea to pull the throttle to idle in a 737 when you're trying to land it. And that it's not smart to stall a 747 because recovering from that is a royal pain the butt!
In all seriousness, could I land a transport category aircraft if I had to? If you define landing as getting it on the ground, sure. If you define it as doing it without killing anyone on board, I don't know. And if you define it as getting it on the ground in a way where it could be reused, the answer is no.
