Take over control of two of the worlds major airport: London Heathrow and Schiphol Amsterdam. The screen display may look docile but you're in the hot seat from which the landing instructions for a host of jumbos and light aircraft are issued.
You're not in the pilots seat this time but make just one slip in stacking those aircraft before landing and you could have a major disaster on your hands. Fortunately, the game has eight play options which help you to train in your new job.
The most simple options include Basic Vectoring where you must guide a selection of aircraft onto your strip, while the most difficult include emergency landings and stacking. If none of those seem easy the author, who also wrote Nightflite II and is an air traffic controller at Heathrow, has included a demonstration which shows how the screen is layed out and the types of command you need to know.
Like many computer simulations it's not graphically impressive but it's the most powerful and authentic simulator of the lot.
