Aiming at the problem of evaluating the maneuverability of aircraft which is useful for detection and aviation against submarine, this paper establishes the evaluation indexes collection of the aircraft and the index matrix of samples to be sorted, and uses the first principal component value of samples for constructing an evaluation index of multi-index system and sorts the samples with this method. In an illustrative example, the synthetic maneuverability of different kinds of aircraft is sorted by using the method proposed in this paper. The result obtained is consistent with the real situation. The example shows that the method is effective and objective thus can be used to evaluate the synthetic maneuverability of aircraft objectively.
