Ladamson, it's strange, I didn't even see the comment above about 'flying on rails' nor have I ever heard anybody comment or mention this. Although I don't follow flight sim forums much. This is just my personal impression of microsoft flight simulator, and the fact that other people have mentioned this too, despite never hearing it until now must have some truth in it. You're being too pedantic about what 'on rails' means. I know exactly what it means as you do, but as you know, compared to how a real light aircraft flies and how one in fsx tends to (probably excluding those made by A2A) the term on rails seems valid. Of course, since you've heard this said so much, I can imagine your frustration too, but I have honestly never heard anybody else say this about FSX, and didn't notice the person above until I scrolled down to see replies.
