and procedures, each with their own size and scope and proceeding at their own pace. Some of these programs include: • • Automatic Dependent Surveillance-Broadcast. ADS-B is NextGen’s surveillance component, where airborne GPS receivers identify an aircraft’s position and trajectory, then transmit their data to nearby ground stations. With that information, air traffic controllers ensure aircraft are safely separated while airborne and on runways. Information on nearby aircraft and other operational data also are broadcast back to suitably equipped aircraft. • Data Communications. Despite growing use of datalinks between air traffic control, aircraft and facilities, ATC communication remains largely voice-based. When fully implemented, routine ATC communications will be text-based and transmitted directly to a capable aircraft’s flight management system, minimizing the current “party-line” environment and, it is hoped, enabling controllers to handle more traffic while improving their productivity, enhancing capacity and safety. • Time-Based Flow Management. This tool expands upon the FAA’s existing traffic management advisor program, which enhances aircraft arrival and departure sequence planning by using time-based metering. The TBFM program is designed to help optimize aircraft flow into capacity-constrained terminal areas, resulting in reduced delays through better predictability of airspace use and improved fuel efficiency. System Wide Information Management. SWIM is designed to be a unified infrastructure and information management system, reducing the number and different types of data interfaces and networks. It can be thought of as the information management architecture for the national airspace system. The SWIM program is being implemented in two different segments.
