You keep saying that. Even if it were true (which I doubt), it wouldn't be important. I call attention again to the scenario I posted: >> The Sim World c182rg is sitting on >> the runway at KSFO.

If you would kindly take a couple of minutes, you could verify that what I say about the SW c172rg is true. If you had the slightest experience in real aircraft, or if you thought about the physics for a moment, you would know that what I say about the RW C172RG is true. Think about it: If the first half of the throttle motion has *no* effect on the MAP, what reason is there to think that the second half of the motion will have any effect? It's just a mechanical valve. It's not psychic. You keep saying that the code is working as designed. So what? That just means that the design is unrealistic. The performance of the model is unrealistic. I said that before looking at the code. > It is definitely not because code section you seem to > love going on about. It was unrealistic before I looked at the code, and it is still unrealistic. Do you really expect anybody to believe that things are OK when pulling the throttle halfway back has absolutely no effect on the MAP? Explaining (again) how the code makes this happen this will not help. The fact remains that it should not happen. The RW aircraft does not do this, and the SW aircraft should not do it either. ------------------------------------------------------------------------------ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
