February 6, 201412 yr Hello everyone. When the aircraft in cruise,aircraft doesn't follow F/D,I use FSUIPC 4.52,I don't know that there is no relationship with this version. How to solve? Thanks!

Hi, WAISINGYUNG, Is the aircraft zigzagging back and forth? If so, it might be due to unrealistic wind turbulence. There is a check box in FSUIPC to smooth wind turbulence that should be checked. You should definitely update your FSUIPC to the current one, which is 4.928. If you have already paid for a registered version, you won't have to pay again. Also, your bank angle looks a little too much for cruise altitude. Is the bank angle selector set to "auto"? Mike
February 6, 201412 yr Also, your bank angle looks a little too much for cruise altitude. Is the bank angle selector set to "auto"? Bank selector should not effect LNAV flight. OP: How is your FPS? On my old computer, I have occasionally seen similar behaviour on low FPS, the autopilot was simply too slow to react and in essence flew an S-curve around the line. --Peter Fabian

Mike Hi,Mike. Should be nothing to do with wind turbulence,Before it is normal, but since yesterday, reloading the game after had changed,I guess it was caused by other plugins,but I just install FSINN,FSUIPC,FPS and PMDG777,So I guess with FSUIPC version of this. Bank selector should not effect LNAV flight. OP: How is your FPS? On my old computer, I have occasionally seen similar behaviour on low FPS, the autopilot was simply too slow to react and in essence flew an S-curve around the line. Hi,Fabo. When this height,FPS is satisfactory.in 3D view about 20~30,So it should be nothing to do with FPS too.
February 6, 201412 yr Could be mistaken but think that if you got the weather ticked in the weather section of fsnn it may cause your issues I7-8700k,Corsair h1101 cooler ,Asus Strix Gaming Intel Z370 S11 motherboard, Corsair 32gb ramDD4,, gtx 1080ti Card, RM850 power supply Peter kelberg

February 6, 201412 yr I dont know but maybe it could be a part of this issue as listed in the issue tracking thread - Fixed a rare issue in LNAV calculation that could cause the aircraft to become unstable on a route leg that lies along a north-south longitudinal meridian. Otherwise it could be the famous S-Turn issue caused by weather. I think the introduction manual speaks to this.

Mike Thank you tcas_climb,and thank all of my friends made the suggestion,After I update the FSUIPC to 4.9 version ,After my test flight(ZGGG-KLAX),This problem seems to have been resolved. Lend a helping hand to thank all friends again!!
