Evaluations of Data Communications in Tower, TRACON, and En Route Air Traffic Control

Abstract

The Federal Aviation Administration (FAA) has embarked on a large effort to create the Next Generation Air Transportation System (NextGen). NextGen will prepare the National Airspace System to accept increasing air traffic levels and complexity in a safe and efficient manner. Data Communications (Data Comm) is one of the core technologies of NextGen. The use of Data Comm will improve information exchange between pilots and air traffic controllers. In 2009, the FAA conducted three human-in-the-loop experiments to address the use of Data Comm in the Airport Traffic Control Tower, the Terminal Radar Approach Control, and the En Route airspace. The experiments focused on human factors aspects of air traffic control tasks under a variety of conditions including varying percentages of aircraft equipped for Data Comm, different interface designs, and changes in roles of responsibilities of air traffic controllers.
