National Air-Tour Formulas and Other Methods of Handicapping

Methods of scoring and handicap used in aircraft competition events are given. The first part contains a historical review, and the second contains criticism of handicap formulas, these having a bearing on aircraft design and the improvement of airplanes. In many cases airplanes are especially designed for air races, and if the design is good, it increases progress. The paper takes up the important formulas for handicapping and considers them from a race and design point of view. Useful curves are plotted.
