A Flight Guidance Display Format on Smart Glasses for Private Pilots

Keeping the pilot eyes-out is important, especially in general aviation (GA), because pilots mostly fly under visual flight rules (VFR). In this study, a display format for smart glasses was developed. Besides the primary flight state information, a curved arrow shows the pilot when to turn and dynamically straightens when the turn should be terminated. The behavior of the display format was developed to guide the pilot in a VFR traffic pattern. A reduction of in flight technical error and missed signals in a secondary task demonstrated the potential of the display format in GA applications. Subjective workload did not significantly change. Results suggest that low-cost consumer smart glasses used in GA could have the potential to support pilots in the future.
