J. Results of flight tests,simulation,and a sensor measurements program are presented in summary form. The flight test portion of the program consisted of a comparative evaluation of various sensor/display configurations in the performance of terrain avoidance,terrain following,and precision hover maneuvers. The simulation effort examined terminal area maneuvers (precision hover,bob-up,sideward flight,and unattended landing) using a panel mounted CRT with various symbology sets and a helmet mounted display. The sensor measurement program obtained obstacle detection data from a variety of sensors under common test conditions for a set of obstacles ranging down to 1/8-inch field wire. In each of these areas,quantitative results are presented along with conclusions based on effectivity of the various systems tested. In addition,subjective results from Phase II of the LLNO effort are included as an annex to the report. (Author) 收起
