You could have saved yourself a lot of work by posting a question before writing all this code. The code to do all this has existed for years. A nice table-driven implementation. It does this and more (notably linking the _pressure_ versus height dependence to the temperature). Pressure is kinda important for realistic altimetry, engine performance, et cetera. Let me know if you are interested in this. The code was never seriously considered for incorporation into the "official" version. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
