Alaska controllers use NextGen ADS-B technology to improve safety

Posted by John McHale

 

ANCHORAGE, Alaska, 25 June 2010. Air traffic controllers in the Alaska region are now officially using Next Generation Air Transportation System (NextGen) technology to improve safety and efficiency in Alaska's rugged terrain, Federal Aviation Administration (FAA) officials say. The system -- Automatic Dependent Surveillance-Broadcast (ADS-B) -- is a core technology under NextGen.

 

Click to EnlargeADS-B provides benefits to both pilots and air traffic controllers. Pilots flying aircraft equipped with ADS-B know precisely where they are and are able to see other aircraft, FAA officials say. ADS-B gives pilots a greater situational awareness when they are near bad weather and also allows them to receive updated flight information including Notices to Airmen and Temporary Flight Restrictions. Air traffic controllers use ADS-B to keep aircraft safely separated in the sky and on the runways.

 

Alaska was the initial test site for ADS-B under a pilot project called Capstone from 1999-2006. Through the Capstone project, the FAA equipped hundreds of general aviation aircraft in Southeast Alaska with ADS-B avionics and installed ground-based infrastructure. Pilots were able to see on their avionics displays where they were in relation to bad weather and terrain and the fatal accident rate was cut nearly in half for equipped aircraft. The success of the Capstone project led to the FAA's decision in 2005 to deploy ADS-B nationwide.

 

"Air travel is the primary means of transportation in Alaska so it's critical to make sure flying is as safe as possible," says FAA Administrator Randy Babbitt. "While the landscape in says is absolutely beautiful, its terrain can be challenging and ADS-B is making a real difference."

 

Controllers at both the Anchorage Air Route Traffic Control Center and at the Juneau Air Traffic Control Tower are using ADS-B, which is critical in Juneau because, like in the Gulf of Mexico, there is no radar coverage. Radar transmissions cannot pass through the mountains in Juneau, making it one of the nation's most difficult airport approaches.

 

Another surveillance system in Juneau that began operating in January is the Wide Area Multilateration (WAM) system. WAM is a ground-based system of small sensors that receive aircraft transponder signals and triangulate them to determine precise locations. WAM provides surveillance for the Juneau area for aircraft not yet equipped with ADS-B. The only other area with WAM is Colorado where the system provides surveillance for mountainous destinations.

 

Alaska is one of four key sites that the FAA selected to test and demonstrate ADS-B services. The other sites include Houston and the Gulf of Mexico, Louisville, Ky., and Philadelphia. Each key site offers a different airspace environment.

 

"NextGen technology is already helping make aviation safer and more efficient," says U.S. Transportation Secretary Ray LaHood. "This innovation is transforming air transportation and every traveler is going to see the benefits."

 

The NextGen plan calls for nationwide deployment of ADS-B by 2013.
