Well, in regard to tracking information, the technology is already being utilized. The technology is called ADS-B (automatic dependent surveillance – broadcast). The ADS-B system is the basic core of Air Traffic Control's NextGen system, both of them topics this magazine has addressed over the past several years. In a nutshell, ADS-B tracking originates from the airplane antenna itself rather than from a traditional radar system, which propagates a signal that bounces back from a target. The antenna from an aircraft sends a signal to a satellite, which sends the signal to a ground-based station, which sends the signal to Air Traffic Control, appearing similar to how it appears now on a controller's display. For the moment, the plan is to require all aircraft operating in specified U.S. control zones to have ADS-B installed by 2020. Most of Europe now has this requirement.
