IFR,VFR rules

[sonic]

Ok I now that "I" stands for Instrument, "V" for visual and "F" for flight,

anything that flys over 12,000ft (I Think) has to use IFR, also some people use IFR to keep up their instrument skills

[legoalex2000]

and besides, all commerical aircraft are required to use IFR. my guess is so the tower knows where the aircraft is at all times...

I think I used IFR once on FS. although i didn't like it, i learned a lot on how to land.

One of the big differances between IFR and VFR is any plane on a IFR flight plan is closely monitored by ATC. They have to get clearance before they change heading or altitude. They also use a specific squawk code to help ATC identify them. This code does not change but stays with the flight untill the plane lands and the plan is closed.
With vfr you are pretty much on your own and have to clear your self before making heading or altitude changes and all vfr aircraft will use 1200 as a squawk code unless they have requested flight following. Then they will be given a different squawk code by each controller and have to switch back to 1200 in between areas.
One of the problems of flying VFR is you have to monitor the weather very closely so your destination airport does not go IFR on you if it does you will not be able to land there.
