This paper describes flight trials performed in Centennial, CO using a Piper Cheyenne owned and operated by Marinvent. The goal of the flight trial was to evaluate the objective performance of pilots using conventional paper charts or a 3D SVS display. Six pilots flew thirty-six approaches to the Colorado Springs airport to accomplish this goal. As dependent variables, positional accuracy and situational awareness probe (SAP) statistics were measured while analysis was conducted by an ANOVA test. In parallel, all pilots answered subjective Cooper-Harper, NASA TLX, situation awareness rating technique (SART), Display Readability Rating, Display Flyability Rating and debriefing questionnaires. Three different settings (paper chart, electronic navigation chart, 3D SVS display) were evaluated in a totally randomized manner. This paper describes the comparison between the conventional paper chart and the 3D SVS display. The 3D SVS primary flight display provides a depiction of primary flight data as well as a 3D depiction of airports, terrain and obstacles. In addition, a 3D dynamic channel visualizing the selected approach procedure can be displayed.
The result shows that pilots flying the 3D SVS display perform no worse than pilots with the conventional paper chart. Flight technical error and workload are lower, situational awareness is equivalent with conventional paper charts.
