A summary of published information on braking friction coefficients is presented. An analysis is included which indicates that the magnitude of the friction coefficient available will affect the technique required for obtaining the shortest ground run only under extreme conditions. In this connection, technique refers to the choice between utilizing air drag and ground friction through choice of attitude. The analysis further shows that the landing attitude is almost never the attitude for the shortest ground run. A chart is presented for rapid estimation of ground-run. A chart is presented for rapid estimation of ground-run distance for any set of values of friction coefficient, airplane attitude, initial drag weight ratio, and initial velocity. Sample studies are presented for high- and low-wing loadings.

An investigation was made to determine the effects of boundary-layer control on the landing performance characteristics of a liaison type of airplane having a payload of 1500 pounds and a flight duration of 5 hours. The aspect ratio was varied from 5 to 15, the wing span from 30 to 100 feet, and the brake horsepower from 300 to 1200. The use of boundary-layer control caused reduction in total landing distance (25 to 40 percent), ground-run distance, gliding speed, and stalling speed whereas sinking speed was increased only slightly.
