@lightning : Thanks!
Cabin Pressure ...
Compass ... yaw ... I had not made that connection
LOX ...
An just for thát indicator I did a lot of work. Build a separate 115VAC 400 Hz power supply (input 24VDC), and a small stepper motor controller, mounted underneath the right side console. I did manage to get the real LOX indicator working, so I guess, I put the needle at some 4.2 at startup, and leave it there.
Adding a lot to the SharedMemoryTester and my "app", it's about time to see how my pit reacts
@Snoopy : I also started with zero knowledge of "Windows Programming", C# and Visual Studio. It is simply learning by doing. However, I am still an amateur. Sometimes, to get things done, I save my work, close Visual Studio, and then start Visual Studio again. I certainly am still not comfortable navigating through all the panes, there are of course more clever ways than close/start again, but it gets the job done
Having done everything "my own way" makes that I have to do the last bits also "my own way"
