MANOEUVRE LOADS DURING TRAINING AND TEST FLYING

摘要

Using continuous photographic trace records, the manoeuvre accelerations experienced in 35 hours of training flying were counted and measured to provide an estimate of the total number and magnitude of loads for a fleet's training flying over a five year period. These data are compared with counting accelerometer data giving the estimated total number of gust plus manoeuvre loads for five years of revenue flying by the same fleet. Both estimates were found to be of the same order in the number and magnitude of loads although the ratio of training to revenue flying hours was one in fifty.nThe particular test flight analysed, which included an unusually large number of stalls, produced approximately as many extreme negative accelerations as one year's revenue flying.
