It has not been resolved. This problem is not in 0.9.10 and IMHO needs to be resolved before releasing 0.9.11. Am I missing/overlooking a fix.
I have been working with Torsten Dreyer to implement the CenturyIII and a derivative AltimaticIIIc autopilot. So I have flown his SenecaII and the pa24-250 a lot while tweaking the two autopilot config files for these autopilots and aircraft. I do not see this issue at all when flying the pa24-250 and I see it every flight with the SenecaII. In the latter case, it is hardly noticable at first with only a slight variation in frame rate ( no more than 5 fps variation from 67 fps). As you continue to fly, the drop in frame rate increases (to 40+ fps after 15 minutes) and the duration of the drop increases. Also the time between drops increases. This has made the optimization of the autopilot config for the SenecaII difficult as this periodic hicup acts as an impulse response to the PID controllers. I am not changing anything but the aircraft between these flights. Two differences between these aircraft come to mind. First, the pa24-250 is a yasim model and the SenecaII is a jsbsim model. Second, the pa24-250 uses only three setlistener in the nasal I maintain and one of these goes away right away after the autopilot is powered up while the SenecaII uses a lot of setlisteners. I am not suggesting the cause, only noting the differences I am aware of between these aircraft.
