Normal acceleration and airspeed data collected in transport airplanes from 1933 to 1945 are summarized and analyzed with respect to gusts and gust loads. The accelerations experieneced experienced in most operations equaled or exceeded the limit-gust-load-factor increment, on the average, twice (once positive and once negative) in 10,000,000 flight miles. The gusts experienced in most operations exceeded 33 feet per second, on the average, twice (once positive and once negative) in 10,000,000 flight miles. The loads experienced for several operations varied appreciably from average conditions. A predominating factor causing the variations in the load experience was the differences in the gust experience, with operating speeds in rough air being a secondary contributing or moderating factor.
