Abstract
AbstractThis article presents the impact of displaying accurate or inaccurate position estimates on air mission commanders’ (AMC) situation awareness (SA) during datalink interruptions between AMC and unmanned aerial vehicles (UAVs). The lack of current information about UAV state and position during datalink interruptions is suspected to negatively influence the controlling AMC's SA. We assume that the AMC's SA can be supported by displaying a state estimate, based on last transmitted data, instead of displaying last known position. An experimental evaluation in a full‐mission research cockpit simulator showed improvements in subjective SA with estimate shown. Objective SA only improved, if the estimate was accurate. Although we expected a negative impact of inaccurate estimates on objective SA (since the user might falsely trust it), none could be observed. Improvements in SA with accurate estimates, but no observable degradations with inaccurate estimates suggest benefits of showing an estimate in any case.
