NextGen, the Next Generation Air Transportation System

摘要

Since the dawn of the Jet Age more than 50 years ago, aircraft technology has undergone many major advances. Today's aircraft are equipped with on-board flight management system computers that optimize routes and automatically guide landings in virtually any weather condition. Technologies use signals from the Global Positioning System (GPS) to enable aircraft to fly paths of approach or departure with an accuracy that some have likened to "flying on rails."
