I've never noticed that "light show" as I always hold the switch longer than 3 seconds :-)
Me too 😊
This is why I said at first I don't see anything in CMC. I actually caught it by mistake.
Rodney sent me a video of the light show but it wasn't possible to see the cause of the problem in it.
I put the switch at DIM and when I wanted to switch it back to BRT, I pressed the upper side and for a split of a second it was in TEST position and then I saw it.
It was 100% coincidence.
Did your CMC apply a time delay before sending back Q variables?
No, of course not. Think what would have happened during CMC start or situation loading: 400 vars * .75 sec delay = 5min (and there are more than 400 vars).
It took me some time but I noticed there was a short delay (later I found it was 750ms) after getting FWD / AFT & MAIN Cargo Fire ARM switch values. When I get them, I update the Equip Cooling valves position (if needed). The reason for the delay in the method was historic and since I added it (it wasn't in v1.0), I made more modifications and it was not required anymore. It just stayed there and until now I didn't notice it caused problems.
Now it is gone.
Cheers,
