HZ-AKA 4 Posted November 28, 2019 Share Posted November 28, 2019 Good Day, During descend using VS command, the trim goes full up and the aircraft starts sinking. Speed is within limits. The aircraft is properly loaded and CG is within limits. Would appreciate in thoughts on this. Regards, Faisal. Link to comment Share on other sites More sharing options...

Developer metzgergva 210 Posted November 28, 2019 Developer Share Posted November 28, 2019 To comment on your observations, I would need more details. Which aircraft and descent at which speed? Happened once or can be repeated? If so can you provide me with the saved situation (4files) to start from and explain what you do to see that behavior? Which hardware controls are you using and how are they connected to P3Dv4? Link to comment Share on other sites More sharing options...
HZ-AKA 4 Posted November 28, 2019 Author Share Posted November 28, 2019 Hi Metzgergva, Aircraft: CRJ 900 and 1000 Pro Decent speed: 200 - 220 kts Happened the two times I flew the aircraft. Hardware: HoneyComb Alpha Flight Yoke and TQ6 PLUS throttle. Connected via USB. Link to comment Share on other sites More sharing options...
Developer metzgergva 210 Posted November 28, 2019 Developer Share Posted November 28, 2019 And what happened exactly assuming you were flying a constant descent in VS mode? Did the AP disengage? Did the value of desired VS change? Did you change the desired VS and then the AP lost control? Link to comment Share on other sites More sharing options...

Developer metzgergva 210 Posted November 28, 2019 Developer Share Posted November 28, 2019 Can you check that in the key assignments for the VSI bug (select) is not assigned to any key. Link to comment Share on other sites More sharing options...
HZ-AKA 4 Posted November 28, 2019 Author Share Posted November 28, 2019 None is assigned to VSI Bug (Select) Link to comment Share on other sites More sharing options...
Developer metzgergva 210 Posted November 28, 2019 Developer Share Posted November 28, 2019 Then I really have no idea what could make the VS change just by itself. I have never seen it before and it would be good if you just specifically test that behavior with different speeds and weather situation to see if you find a reproducible situation to share. Sorry I can't help any further. Link to comment Share on other sites More sharing options...

Sorry I can't help any further. I flew the CRJ 700 today and no issues at all. I will try the CRJ900 later and see if the issue is still there.
