Hello,
As far as I remember pre-SU9 the simulation variable "CAMERA STATE" was still on "11" when in the "READY TO FLY" screen. Since SU9 it is no longer the case and therefore it cannot be used any longer to detect being in the "READY TO FLY" screen. I've also seen that simulation time now beings to increase in this screen as well, so this cannot be used any longer, too.
How can it be detected that a user is on the "READY TO FLY" screen?
The reason this is needed is the following:
I've noticed that some initialization happens when you press the "READY TO FLY" button. We set the Autopilot Speed Slot Index to "1" in our initialization. You clearly see this when watching the variable while being in the "READY TO FLY" screen. Now when you press the "READY TO FLY" button it jumps again to "2" as it is on the entrance of the screen. When you're clicking fast on the "READY TO FLY" this jumping back to "2" does not happen, because our initialization code is not called yet.
The idea would be now to wait to run the initialization code until the user has pressed the "READY TO FLY" button.
