Abstract : A De Havilland DHC-6, Series 100 Twin Otter was flown by a representative group of pilots on various steep-gradient approaches onto a ground-level STOL runway. Approximately 800 approaches and landings were accomplished to provide a data base to approve a first-generation STOL operation. Areas investigated included: Aircraft handling and response on steep-gradient approaches with various approach electronic beam sensitivities; location of the ground point of intercept; co-located versus split localizer/glide slope signal source; obstacle clearance requirements; field length requirements; and influence of command-steering on aircraft/pilot performance.
