Abstract

THE RESULTS OF THE ANALYSIS IN PHASE I OF MINIMUM FIELD-OF-VIEW (FOV) REQUIREMENTS FOR NON-INSTRUMENTED LANDINGS ARE SPECIFIC ENOUGH TO MERIT CRITICAL EVALUATION IN FLIGHT TESTS UNDER A RANGE OF VISUAL METEOROLOGICAL CONDITIONS. THE TECHNICAL OBJECTIVE OF PHASE II IS TO VALIDATE THE MINIMUM FOV REQUIREMENTS ADDRESSED IN PHASE I. COUPLING THIS TECHNICAL OBJECTIVE WITH EXPERIMENTAL ISSUES IN VISUAL APPROACH AND LANDING OPERATIONS WILL ENABLE THE PHASE II PROGRAM TO EVALUATE PILOT ACCEPTANCE OF AND PILOT-VEHICLE PERFORMANCE WITH RESTRICTED FIELDS OF VIEW PROVIDED OPTICALLY BY A RESEARCH EXTERNAL VISION DEVICE. THIS INVESTIGATION OF RESTRICTED FOV REQUIREMENTS FOR NON-INSTRUMENTED LANDINGS WILL INCLUDE PRE-EXPERIMENTAL PLANNING IN CONJUNCTION WITH THE NATIONAL AERONAUTICS AND SPACE ADMINISTRATION (NASA); ASSISTING NASA IN CONDUCTING AND ACQUIRING DATA FROM FLIGHT VALIDATION EXPERIMENTS; AND ANALYZING, INTERPRETING, AND DOCUMENTING THE RESULTS THEREFROM. IN ADDITION TO VALIDATING RESTRICTED FOV REQUIREMENTS, RELATED EXPERIMENTAL ISSUES TO BE ADDRESSED INCLUDE APPROACH GLIDE PATH ANGLES, FLARE TRAJECTORIES, EXTERNAL VISUAL APPROACH SLOPE AIDS, RUNWAY VISUAL RANGE, AND RUNWAY SITES, DELINEATION, TEXTURE, AND ILLUMINATION THEREOF. ENSEMBLE, TEMPORAL, AND FREQUENCY DOMAIN STATISTICAL ANALYSES ARE PROPOSED FOR INTERPRETING RESULTS IN TERMS OF THE INDEPENDENT EXPERIMENTAL VARIABLES.
