September 18, 201015 yr I level off the aircraft at an altitude, select the aileron and elevator axes on, then select the altitude hold on. The autopilot then immediately runs the trim all the way nose down and the aircraft descends way below the selected altitude. This doesn't happen on the real aircraft. Can anyone tell me what is wrong? Thanks.

Thanks.This happens when a joystick's elevator axis is not zero...the likely culprits are a noisy pot that's generating momentary excursions outside the center dead zone, or the stick is not calibrated properly and not zero when centered, or your dead zone is too small (or some combo of the above). It's also possible if you have a second joystick or game controller that FS has mapped to the elevator axis...noise or a nonzero input on the second device can do this as well.When the A/P is engaged, even a small nonzero input held over a period will result in a situation where a large cumulative pitch change is commanded.Recalibrate your joystick, and consider using FSUIPC to establish a sufficiently large dead zone so that minor pot noise does not result in a nonzero input with the stick centered. Also, you might want to watch the axis to see if it's bouncing around alot, which happens when a pot wears out.RegardsBob ScottColonel, USAF (ret)ATP IMEL Gulfstream II-III-IV-VColorado Springs, CO Bob Scott | President and CEO, AVSIM Inc ATP Gulfstream II-III-IV-V Sys1 (MSFS20+24/XPlane12+11): AMD 9800X3D, water 2x240mm, MSI MPG X670E Carbon, 64GB GSkill 6000/30, nVidia RTX4090FE Alienware AW3821DW 38" 21:9 GSync, 2x4TB Crucial T705 PCIe5 + 2x2TB Samsung 990 SSD, EVGA 1000P2 PSU, 12.9" iPad Pro Thrustmaster TCA Boeing Yoke, TCA Airbus Sidestick, Twin TCA Airbus Throttle quads, PFC Cirrus Pedals, Coolermaster HAF932 case Sys2 (P3Dv5/v4): i9-13900KS, water 2x360mm, ASUS Z790 Hero, 32GB GSkill 7800MHz CAS36, ASUS RTX4090 Samsung 55" JS8500 4K TV@60Hz, 3x 2TB WD SN850X 1x 4TB Crucial P3 M.2 NVME SSD, EVGA 1600T2 PSU Fiber link to Yamaha RX-V467 Home Theater Receiver, Polk/Klipsch 6" bookshelf speakers, Polk 12" subwoofer, 12.9" iPad Pro PFC yoke/throttle quad/pedals with custom Hall sensor retrofit, Thermaltake View 71 case, Stream Deck XL button box Sys3 (DCS/P3Dv4/ATS/ETS): AMD 7800X3D, MSI MPG X870E Carbon, Noctua NH-D15S, 64GB GSkill 6000/30, EVGA RTX3090 Alienware AW3420DW 34" 21:9 GSync, Corsair HX1000i PSU, 4TB Crucial T705 PCIe5 + 2TB Samsung 970Evo Plus, TM TCA Officer Pack, Saitek combat pedals, TM Warthog, TM RS300 FF wheel/pedals, Coolermaster HAF XB case
September 18, 201015 yr Author Thanks for your help Bob. I increased the elevator axis dead zone and that solved the problem!
September 20, 201015 yr You can also engage Aileron and Elevator Servos after 1000ft to activate the CWS for AILE e ELEV channels (roll hold and pitch hold) Gustavo Rodrigues - Brazil
October 25, 201015 yr I saw this too, running out of trim, and a high pitch sensitivity.Both I cured in my airfile edit.Even a very nice and stable CWS is working this way.Now only the performance tuning and I might release the edit if there is interrest in it.Btw, I would like to thank the team for this wonderfull freeware!
October 25, 201015 yr Author I would be interested in your edit, Johan. CWS doesn't seem to be working very well for me.
