Aircraft accident data was analyzed to investigate the differences in risk of Naval aircraft and to develop some overall risk measure. To analyze risk, a flight was divided into four risk areas takeoff, inflight, transition, and landing. Accidents were assumed to occur according to a Poisson process and tests were carried out to prove the validity of the Poisson assumption. The poisson model yielded two factors, the exposure to the risk areas and the performance in them. A procedure to predict risk was developed. A statistic, improvement index, was developed to allow a direct comparison between different types of aircraft with respect to safety performance. Modified author abstract
