The Federal Aviation Administration announced on Thursday (6/24) that air traffic controllers in the Alaska region are now officially using Next Generation Air Transportation System (NextGen) technology. The system - Automatic Dependent Surveillance-Broadcast (ADS-B) - is a core NextGen program technology.
(FAA) "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."
