Contract Analog Simulator Evaluations: Vertical Display with Horizontal MAP Display

摘要

Evaluation was made of the pilot's ability to navigate and to perform simulated helicopter terminal area maneuvers using contact analog vertical display symbology alone and in the presence of the horizontal map display. Combinations of the grid, flight pathway and ground position indicator (GPI) on the vertical display with and without the map display were investigated. Performance measures were taken of the terminal area maneuvers including the landing approach, transition to hover, hover and touchdown. In general, the cruise portion of the flight could be accomplished as well when using the basic grid plane on the vertical display in the presence of the map display as when additional symbology (pathway and GPI) was presented on the vertical display. Performance on the approaches and transition to hover scores indicated improved performance with the additional information provided by the pathway and the GPI. It was concluded that precision of performance could be improved with the pathway and GPI navigation features on the vertical display but successful accomplishment of terminal area maneuvers was not entirely dependent upon this information.
