Pilots in Alaska’s mountainous Yukon-Kuskokwim Delta have had to fly without radar, and normally below 2,000 feet, to avoid foul weather and icing. They would slalom through canyons on memory. Since 2000 the FAA has installed five ground base stations and equipped 200 planes with ADS-B gear. Now pilots get weather warnings and detailed traffic conditions and topographies. Accidents are down 50%.
