Federal Aviation Administration

When the summer travel season begins, airline passengers typically brace for delays as vacationers fly in larger numbers and the inevitable weather-related disruptions occur.

The Federal Aviation Administration, which oversees the nationwide system of air traffic control, is hoping to make some of those delays a thing of the past. It's developing what it calls "Next Generation" technology. The NextGen program will modernize the air traffic control system, transforming it from radar to GPS-based technology.
