That sounds to me like the difficulty is in choosing (finding?) the coefficients, rather than in the coding of JSBSim? I don't mean to minimize the difficulty of finding all of those coefficients, but in some sense that is really a different problem than can JSBSim do it? No new code is

Adam Dershowitz writes Typically the spoilers will only deploy above some yoke position threshold (maybe actually a roll rate?), and then they can, of course, only deploy up, so only one is involved at a time. Unfortunately this is not the case with Boeing jet transport aircraft(707,727,737,747
