stehul Posted January 22, 2022 Share Posted January 22, 2022 (edited) Sorry for maybe bad english. I have noticed a strange behaviour when I am flying on LNAV with the Levelup 737NG. Without explanation the aircraft diverges from the LNAV path. For example this morning I flew LROP to ESSA with the Levelup 737-700. The flight went well until the aircraft just changed heading from the LNAV path. I created the flight plan in Navigraph Charts and I am using the latest AIRAC cycle. Can this be some sort of bug? When I am thinking more of this I noticed the same bug(?) in the latest version of the Zibo mod. The LNAV lamp is still enabled when this occurs. I will now try the same flight with the same flightplan in the default 737 and see if the same happens....

stehul Posted January 22, 2022 Author Share Posted January 22, 2022 I have now tested the same flight with the default 737-800 and everything is working. So I guess this is a (kinda new) bug in the Zibo mod which is also in the Levelup 737NG. Link to comment Share on other sites More sharing options...
samy_k97 Posted January 23, 2022 Share Posted January 23, 2022 Hi, Is this 100% reproduceable? If so does the same happen with the Zibo 738? Link to comment Share on other sites More sharing options...
stehul Posted January 23, 2022 Author Share Posted January 23, 2022 (edited) I will try now with the latest Zibo and let you know in a couple of hours! At least it is 100% reproduceable with the Levelup 737. Edited January 23, 2022 by stehul Link to comment Share on other sites More sharing options...
stehul Posted January 24, 2022 Author Share Posted January 24, 2022 (edited) I could reproduce the exact behavior with the latest Zibo mod (3.51.19). Just after waypoint GELDA the aircraft starts to turn heading 295 instead of going to NILUG. I have attached the flightplan I used as a txt file if that may be helpful. And as I said earlier, the default 737-800 follows the flight plan as it should. I dont know where to find older Zibo versions to test with. It seems like its not possible to access Zibos Google drive any more. And on the Zibo updater page I just find the latest versions. But I can try the flight with the 737-700 Ultimate too:. I am sure it will follow the flight plan. LROPESSA.txt Edited January 24, 2022 by stehul Link to comment Share on other sites More sharing options...
stehul Posted January 24, 2022 Author Share Posted January 24, 2022 I have tested more during the day. And now I can say 100% sure that this bug(?) only is when I am flying on a flightplan created in Navigraph Charts and flying it with Zibo/Levelup. I just created some flightplans witn Online Flight Planner and both Zibo and Levelup can fly them without any strange behavior. 1 Link to comment Share on other sites More sharing options...
