airplane in commercial operation on an eastern united states route from November 1947 to February 1950 An analysis of 48,187 hours of normal-acceleration and airspeed data obtained on a four-engine type of transport airplane in commercial operation on an eastern United States route from November 1947 to February 1950 has been made to determine the gusts and gust loads for the operations. The results, covering operation to 20,000 feet, indicate that the maximum gust velocity encountered in a given number of flight miles was less than that for a low-altitude operation (below 10,000 feet) but the accelerations experienced were about as severe in terms of percentage of limit load factor as for the operations below 10,000 feet.
