Essentially an airport traffic control tower simulator. Your mission here is to manage the aircrafts in Phoenix Sky Harbor International Airport's airspace from the control tower. There is no "winning" in this game; you play rounds of varying difficulty in which you must direct planes through waypoints, clear planes for takeoff, change altitude, etc. without them crashing or colliding in mid-air. You can select your difficulty from a series of pre-defined options or make your custom rounds by selecting parameters such as numbers of planes, time available, etc.
The game screen is divided in two, with the upper half being your view from the tower, and where animations for different events happen (crashes, etc.) and the lower half the being the main game interface where you have your radar and communications interfaces.
In addition to the main game, the CD includes a series of complementary materials regarding planes and other reference info.
