Abstract:

Load spectra for the Australian fleet of Orion P-3C aircraft are presented and compared with the ESDU 69023 discrete gust and the US MILSPEC A- 8861A power spectral model, which are here called the baseline models. The turbulence experienced when flying over the sea is about one half of that predicted by the baseline models. The sea appears to reduce the turbulence by a greater amount, and to higher altitudes than indicated by the over Australia, are about five times as severe as predicted by the baseline models. This supports other observations of a higher than normal incidence of the altitude turbulence 25,000 ft and above over Australia. JES
