I found it very useful as a procedural trainer when i was doing my IR as most of the radio navaids are accurately portrayed, and you can use actual weather/wind. Didnt bother trying to handle it, just used a generic aircraft with autopilot to fly the thing with some stability and concentrated on the procedures. The IOS facitlity is also very useful for seeing how you tracking/holding/point to point etc works out, but that is about it. Havent used it since though. Definitley NOT worth trying to practice/learn any handling on it. Learning to hover on a computer game - definitely not, unless you have a full control set up with hydraulic motion!
