Airport City: What do I need a Ground Control for?

We introduced the Ground Control to Airport City so that it is easier for you to direct flights. Put this building in your airport, and you will be able to set automatic refueling and boarding while preparing a flight or receiving guest flights. To do this, you need only to choose the Ground Control and activate automation. You can also disable this function any time you want. The Ground Control is available to all players level 6+.
