How Glider Pilots Misread the FLARM Collision Alerting Display A Laboratory Study

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 indications 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 showed that errors in the initial search direction for traffic increased whenever the ownship did not fly straight and level. These errors are attributed to a misunderstanding of the system’s indications. Three recommendations are made with the goal of reducing future misinterpretations when using the system.
