How glider pilots misread the FLARM collision alerting display: A laboratory study.
In: Aviation Psychology and Applied Human Factors, 4 (2), pp. 86-97. [Article]

Abstract

During the last decade glider pilots have been provided with new tools to assist them in their task of seeing and avoiding other traffic; low-cost collision alerting systems (CASs). However, the display of the popular FLARM CAS lacks clues about the system's limitations. To analyze whether glider pilots are aware of these limitations a laboratory study with 43 glider pilot participants was performed. The results show that errors in the initial search direction for traffic increase whenever the aircraft does not fly straight & level. These errors are attributed to a false understanding of the system's indications. Three recommendations are made with the goal of reducing future misinterpretations when using the system.
