I'm a pilot. I mean for real. Like certificated. My question is, why
aren't sims worth a damn? They're cheezy and crappy. The flight models
are wrong. The radio equipment doesn't work right. The terrain isn't
photorealistic and I can't pull negative Gs. You can't do pilotage.
The dead reckoning doesn't match up with real charts. What's wrong
with those computer programming geek f0ks? Can't they get anything
right?

It depends on what sim you have in mind; they are all different.

As far as desktop simulators go, a very large community of regular simmers
would disagree with you, and many of them are also "real" pilots.

When it comes to more advanced simulators, virtually none of your complaints
has any basis.

When will I be able to learn something from a sim?

Some pilots learn humility in a sim.
