No mention of approach glide angle either. I have no idea how this applies to rotorcraft since I only dug into the traditional "winged" code. A quick search through fgdata/Aircraft revealed the following aircraft to have different glide angles specified for approach and cruise: - ASK13 - ASK21 - ASK21-MI - IAR80 (fixed by Emilian I believe) - PaperAirplane ASK13 and PaperAirplane have the biggest difference between the two numbers (23 vs 2). The fuel is a different matter, a very large number of aircraft have numbers other than default. As far as the solver is concerned, the glide angle has a very large influence on the coefficients, while the fuel has a relatively small relevance in the final numbers. Adding a tag which would be used on the new models could retain compatibility for older aircraft which are no longer developed. On the other hand, it would be a pity to have the very clean code of YASim cluttered by special cases for bugs. It's a tough choice, your call I guess.
