Next Generation (NextGen) Data Communications (Nexcom or Data 2023 Comm), an element of the Next Generation Air Transportation System, will significantly reduce controller-to-pilot communications and controller workload, whilst improving safety.[1] NextGen comprises complex integrated and interlinked programs, portfolios, systems, policies, and procedures. NextGen has modernized air traffic infrastructure in communications, navigation, surveillance, automation, and information management. [2]
In the current United States National Airspace System all communications with airborne aircraft is by voice communications. Aircraft route of flight revisions must be communicated through multiple change-of-course instructions or lengthy verbal reroute instructions, which must be repeated; are prone to verbal communications errors; and entry errors into an aircraft's flight management system. The use of voice communication is labor and time intensive and will limit the ability of the Federal Aviation Administration (FAA) to effectively meet future traffic demand in the United States.
Adding air-to-ground and ground-to-ground data communications will significantly reduce controller-to-pilot communications and controller workload. The data communications will enable ground automated message generation and receipt, message routing and transmission, and direct communications with aircraft avionics.
Initially, data communications will be an additional means for two-way exchange between controllers and flight crews for air traffic control clearances, instructions, advisories, flight crew requests and reports. Eventually, the majority of communications will be handled by data communications for appropriately equipped ground and airborne stations. Data communications will enable air traffic control to issue an entire route of a flight with a single data transmission directly to the aircraft's flight management system.
NexCom will be an eventual replacement for the existing Future Air Navigation System that is currently used primarily by transoceanic commercial airliners.[3]
