The purpose of this study is to determine if differences in the accuracy of the state of the art in estimating and achieving aircraft weight empty exists for two periods. Using two tests: the Wilcoxon and means comparison, it was determined that a low probability exists that the two samples are different. Therefore, it is likely that there has not been a change in the accuracy of the state of the art, statistically speaking.}, keywords = {21.
