Assessment of Current and Proposed Audio Alarms in Terminal Air Traffic Control

The National Airspace System Human Factors Branch (ACT-530) has been engaged in research on the characteristics and use of audio alerts and alarms in Air Traffic Control. In support of this program, Federal Data Corporation performed a comparative study of current audio alarms used in airport towers and Terminal Radar Approach Controls (TRACONs) with those proposed for use with the Standard Terminal Automation Replacement System. This study involved a review of relevant documents and extensive discussions with personnel at the Detroit Wayne County Metropolitan Airport (DTW) Tower and TRACON. The authors evaluated the current and proposed audio signals relative to studies on discriminability and audio signal use and existing design standards. In addition, they examined several operational issues raised by the DTW personnel. They present recommendations for initial implementation and long-term studies and modifications.
