I know that I am one heck of an instinctual pilot, but some of the credit has to go to MS.
That is the first time I have ever heard anyone publicly say they think they are a good instinctual pilot. Other people tell you that you are a good stick, not yourself. End rant.Cocky.
If you want to buy flight sim for somthing fun to do everyonce in a while I'd say go ahead. If you want to get it to prepare yourself for real flying I'd say no. Flight Sim is good for practicing instrument procedures not for initially learning to fly (If you have charts). It may give you an introduction to what a 172 cockpit looks like but thats about it. If anybody thinks that they became some kind of flying prodigy from playing flight sim they're full of it.
Bottom line, it wont hurt you to play it but realize that you won't be any better off than every other new pilot. You're going to be overwhelmed the first time you fly but it's part of the journey so just enjoy because you won't always have the wonderful excuse that you're just starting out.
I am in the nuclear field currently, and they always rant and rave that it is the hardest school in the Navy ( I highly doubt it) but how hard is the flight path and how many people fail out of it and are forced into other areas of the navy?
