Heathrow Air Traffic Control is a simulation game about managing air traffic at London’s Heathrow Airport. The player takes the role of an air traffic controller and is responsible for guiding incoming aircraft to safe landings while avoiding collisions and maintaining proper separation.

The gameplay is presented through a top-down radar-style display. Aircraft approach the airport from different directions, and the player uses keyboard commands to assign headings and speeds to each plane. Planes must be sequenced and guided onto the runway, taking into account wind direction and traffic density. The game becomes more complex across levels, requiring increasingly efficient management.
