drone simulation project

[elodie]

Hello
I plan to make a FlightGear simulator, this simulator has the distinction of being divided into two computers. One will calculate the drone FDM and the other will display the instrument (the ground station).
I did some research in the source code and saw that we had 6 classes, updated successively SGsubsystem :: INIT, SGsubsystem :: GENERAL :: SGsubsystem FDM SGsubsystem :: POST_FDM, SGsubsystem :: DISPLAY, SGsubsystem :: SOUND. In those classes are other subsystems or are data that can be found in the property tree.

I am close (I hope) to understood, but if not where are my mistakes?

For my simulator I need to do real-time, it’s why I need to know how all the data are scheduled.
I want to know if those classes are all updated in the same tick or if each is updated in a different tick. Or tell me where I can found this information.
For my project I want a PC that calls only INIT and FDM, and the other INIT, SOUND, GENERAL and DISPLAY. It’s why I want to know how this is scheduled.

Thank you

I assume you mean a stationary cockpit with real controls, like they use to train pilots?
