摘要

While the FAA's selection of a contractor to build what may become a nationwide ground-based ADS-B system by 2013 is viewed as a major step forward for air traffic control, technical experts note that the greatest benefits could take more than a decade to arrive.rnThe ADS-B ground system contract awarded by the FAA to a team led by ITT on Aug. 30 is valued at $1.8 billion. It will bring a revolution in air traffic surveillance of the type not seen since the end of World War II when radar entered civil service. But then there's the age-old chicken-or-egg problem in developing new ATC systems: Until there is universal avionics equipage (the egg), the ground-based network (the chicken) will only be partially effective. The FAA is well aware of the problem and wants to accelerate near-term opportunities to produce ADS-B benefits for users. This will help motivate them to buy avionics equipment earlier.
