Abstract:

Evaluations were flown in the Aero Jet Commander, Gates Lear Jet, North American Sabreliner, and Lockheed JetStar. Approach slope angles were varied from approximately 3 degrees up to almost 7 degrees. Flight parameters were measured in the areas of descent airspeed, power requirements in flare, flyability, sink rates, threshold crossing heights, and touchdown distances. Objective and subjective measurements were made. It was found that when approach slop angles above 4 degrees approximate minimums of 400 feet altitude - 1 mile visibility were used they were accompanied by problems of power requirement, flyability, high sink rates, and long touchdown distances.
