CIVIL AIRCRAFT AIRWORTHINESS DATA RECORDING PROGRAMME
MANOEUVRE LOADS DURING TRAINING AND TEST FLYING
by
G. E. King
SUMMARY
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.
The particular test flight analysed, which included an unusually large
number of stalls, produced approximately as many extreme negative accelerations
