Further Lessons Learned in the Design of Computer-Human Interfaces for Terminal Air Traffic Control Systems

Abstract

The Standard Terminal Automation Replacement System (STARS) will replace aging radar data processors and controller workstations at Federal Aviation Administration (FAA) and Department of Defense (DoD) terminal air traffic control facilities. In the late 1990s, computer-human interface (CHI) issues were identified with the major STARS components. Since then, many CHI modifications that make STARS easier to use, easier to maintain, and more acceptable to the controllers and airway facilities technicians have been prototyped, implemented, and tested. We are currently designing CHIs for upcoming enhancements in which decision-support tools, satellite-based surveillance, and advanced weather information will be integrated into STARS. This paper will discuss lessons learned during the STARS CHI development that may interest acquisition programs dealing with similar issues. Specific examples include the development of monitoring systems, the design of target symbols, and the depiction of weather information.
