The US state of Alaska has deployed next generation (NextGen) air transportation system technology to improve safety and efficiency in the region's rugged terrain.

The automatic dependent surveillance-broadcast (ADS-B) system, a core technology under NextGen, is used at the Anchorage air route traffic control entrance and at the Juneau air traffic control tower.

ADS-B is essential at these sites as radar coverage cannot pass through the mountains in Juneau, making it difficult for air traffic controllers to identify aircraft approaching an airport.

An aircraft equipped with ADS-B will enable pilots to know their precise location and see other aircraft.

It will improve pilots’ situational awareness during bad weather and provide them with updated flight information including notices to airmen and temporary flight restrictions.

Air traffic controllers will use ADS-B to keep aircraft safely separated in the sky and on the runways.

The Federal Aviation Administration has equipped several general aviation aircraft in Southeast Alaska with ADS-B avionics and installed ground-based infrastructure, under a pilot project called Capstone from 1999-2006.
