It depends on what you're trying to model, and whether you want to have any semblance of realism. -- One can imagine a super-fancy inertial navigation system that could report the /position of the aircraft as suggested above. ++ However, most aircraft do not have such a thing. ++ If you did have such a thing, you would not be allowed to use it as your primary altimeter. There are regulations as to what altitude must be flown, and these regulations are written in terms of barometric altitude. That is not equivalent to true altitude. ++ Some of us (not all, of course) would like to get FG to the point where it would be usable as a procedures trainer. This requires modeling the instruments "warts and all". As a start, this includes modeling the nonidealities of the barometric altimeter ... such as H-A-L-T among others. ------------------------------------------------------------------------- Take Surveys.
