I have extensive experience in reporting detailed bugs on mobile flight simulators and have helped developers correct these issues like X-Plane Mobile for example. But the preparation of these reports is quite laborious and I even spend about 1 hour and 30 minutes producing them outside the time I spend investigating the bug in the simulator and reproducing it accurately. I can commit to writing a highly detailed report but I need you to help me too because the more people report the same problem gets even better for it to be identified and corrected. For this specific bug it is necessary to record a video for developers to understand and identify the problem. The video needs to be recorded at the exact moment the bug occurs. At least here for me it has happened several times from the Boeing 787 LNAV and VNAV functions if they turn off on their own without my interference. When they turn off I turn them back to continue the flight.
I won’t be back in a 787 until probably next week, I did Newark to Madrid today on the 773 and will fly back to Madrid at the end of this week. My next flight will probably be Newark to lisbon so if this does happen again I’ll definitely try to record it. Saying that, LNAV hasn’t disconnected for me recently, I think it might just be the steep turns in the flight plan (although ThomK didn’t seem to have a problem). It’s hard to anticipate when the lnav will disconnect and what conditions have to be met but if it happens while I’m monitoring the climb out of Newark, or even when I get down route to lisbon I will definitely record the replay and show my complete lack of interaction which still causes a pretty crucial flight mode to just disconnect. Maybe my sim is cursed 👀
