Aircraft Situation Display

The Aircraft Situation Display provides information about airplanes flying over the United States at any moment. Each dot on the screen represents an airplane in flight. Can you guess how many airplanes are shown on this map? Touch the answer button to find out. If you guessed 9 airplanes -- you’re right! For every one of those airplanes, the ASD knows its identification number, location, speed, direction, and altitude.
