Preflight Test Simulation of Superimposed Integrated Trajectory Error Displays.

摘要

The report describes a man-machine simulation of an image display (TV video terrain image) enhanced by the superposition of symbology conveying quantitative information. A hierarchy of symbolic displays with increasing information content superimposed on a TV video terrain image is developed as an aid in approach and in precision hover. The most sophisticated configuration required ground position information. To obtain ground position information, a position sensor which utilized a ground beacon radio such as the Electronic Location Finder (ELF) was simulated. The position information was shown to be necessary to obtain hover precision of less than five feet. Aircraft stabilization equipment (ASE) was also found necessary. (Author)
