Tower Controller

I was wondering, is the tower controller feature single player also, or is it just multiplayer, and if it can be single player, tell me how to get to it. I have the Deluxe version.

I have had a little look at this. As I can't seem to get a log in for multiplayer mode I set the local LAN option and this allows you to enter as a tower controller. The Tower and controller screen is shown and active but no Autogen traffic was shown . I think you can only control aircraft when in multiplayer mode. Looks like an interesting feature
