Hello Dave @DGymer!
Yeah, that was my first thought, too. But in my case things are just the other way round - MSFS ignores my input (or better: treats my input not the way it should, i.e. the way it treats input via its own UI). The display just reveals these different treatments.
But ok, as long as MSFS doesn’t handle input correctly I wil have to cope with it by not having the comfort to pre-select altitudes and to activete them later.
Yep, that helped a lot. I’ve just implemented the logic and the LOC and APPR buttons work now like a charm!
In fact, just the AP1 and AP2 buttons are missing. All other inputs and displays incl. button lighting works well.
A very big THANKS to you for your answer which helped me a lot! Nice to have someone out there who is not only knowing but also sharing his knowledge!
Greetings,
Jens
