OK so I get a general Idea of how to use them by looking at othe rpeoples work, but.,. is tehre a detailed explanation of how to use them_ DO I need more than a taxy set for each end of teh runway? so I need to start where I belive the IA will stop, or do they go to the end of the marked runway? do we know how the IA chooses where to stay, can it "see" if the spots are allready ocuipied?
Any general tips?

Thanks!
