Ditto what has been said already. They don't replace a trainer.

Think of it this way. I use Microsoft Fligth Simulator and I can fly a 747 from one coast to the other. Do you think that I'm ready to take the controls of a real one??

In fact, if a simulator is used incorrectly it can actually do more harm that good. You can develop very bad habits from using a simulator without proper instruction.

Here's a list of some of the "bad" habits one can develop:
1) Failing to keep the plane straight during takeoff run.
2) Climbing out too steep.
3) Not maintaining a constant altitude while turning.
4) Turns that aren't smooth, too sharp, etc.
5) Forgetting that there is a left stick.
6) Not lining up with the runway during landing approach.
7) Using ailerons instead of rudder to make course corrections when landing.
8) Using the elevator to extend the landing when you realize you're short.
9) Failure to learn the signs that a plane is about to stall, and what to do to avoid it, or recover from it.


The sim is NOT:
[ul][*]Going to teach you how to tune your engine [*]Going to teach you how to correct fuel system problems [*]Going to teach you how to set up your linkages [*]Going to show you about lateral inbalance and surface warp [*]Going to locate errors in assembly [*]Going to teach you how to maiden a plane [*]Going to trim out your plane [*]Going to simulate other flyers at the field [*]Going to blow a hard gust of air at your plane at just the wrong time [*]Going to simulate that hard sink thermal just off the runway threshold, though doable in G4 [*]Going to have a bird come out and attack your plane in the air [*]Going to give you the weak knees you'll get the first time you fly [*]Going to throw a bug in your face and the sun glare in your eyes at the wrong time
