Jagdgeschwader Posted February 2, 2022 Share Posted February 2, 2022 Hi, I am new to the Viggen and I really love this aircraft but every time when I do a long mission with landing, re-arm and take off again i encounter this issue with the HUD symbology. I have tried a few suggestions how to fix it but they never worked for me. What i've tried: 1. Setting the QFE to the value of the takeoff and landing airfield. 2. Setting the landing airfield to waypoints LS and L1. 3. Fast erecting the ADI. Here is a screenshot, it's not mine but that is the issue i described. Maybe I am doing something wrong or I missed something. Thanks and sorry for my English. "If we don't end war, war will end us." H. G.

Machalot Posted February 3, 2022 Share Posted February 3, 2022 We have reported these issues with an attitude reference drift to HB. But that screen shot is the worst I've seen. "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic. And reentry from space, well, that's like Mach a lot." Link to comment Share on other sites More sharing options...
Jagdgeschwader Posted February 3, 2022 Author Share Posted February 3, 2022 I couldn't find a better one but it decribes the issue well. Thanks for replying. Now I'm confident that it's not my mistake or something I did wrong. "If we don't end war, war will end us." H. G. Wells Link to comment Share on other sites More sharing options...

You switch back to NAV, when you're back on the runway after rearming. If you do this, there should be no such issue with the HUD. 1 Intel i7-12700K @ 8x5GHz+4x3.8GHz + 32 GB DDR5 RAM + Nvidia Geforce RTX 2080 (8 GB VRAM) + M.2 SSD + Windows 10 64Bit DCS Panavia Tornado (IDS) really needs to be a thing!

Switching to BER is only to do with the navigation system itself (as far as I'm aware), and should not affect the gyros. Viggen is love. Viggen is life.

Machalot Posted February 5, 2022 Share Posted February 5, 2022 1 hour ago, QuiGon said: Your HUD is loopsided even after doing this? In my case it was shifted below the horizon. Roll drift was not noticeable. It did not resolve by BER nor Fast Erect. This is a tracked bug. "Subsonic is below Mach 1, supersonic is up to Mach 5. Above Mach 5 is hypersonic.

QuiGon Posted February 5, 2022 Share Posted February 5, 2022 Hmm, in my experience a loopsided HUD is the result of switching from BER to NAV while still taxiing around corners.

Jagdgeschwader Posted February 10, 2022 Author Share Posted February 10, 2022 Thanks everyone for the help looks like there's nothing we can do so we'll have to wait until it gets fixed. btw the last update didn't fix it as well.
