AIRLINERS and air-traffic-control centres are in the process of adopting a new navigation system, called Automatic Dependent Surveillance-Broadcast (ADS-B), which uses the satellite-based global positioning system to work out where an aircraft is. ADS-B is more accurate than the existing arrangement, which is based on radar and signals from radio beacons, and will supplement it. Among other things, this should make automatic collision-avoidance systems more reliable. The anti-collision equipment currently fitted to jets has already helped make mid-air encounters between airliners rare, but many light aircraft and helicopters are not fitted with such kit. On average there are 12 mid-air collisions between small aircraft in America every year, causing 19 deaths—and a lot more near misses.
