description abstract	It has been found that for wings combining high aspect ratio with large mounts of sweep, the Weissinger seven-point results are in error. A simple procedure is presented here which for a sizable range of plan . forms largely corrects these errors and results in more accurate span loadings being read directly from the loading charts of NACA Report 921. This procedure consists of an alteration of the taper ratio used plus an 4. additional correction applied at the wing root. In the above procedure, the lift-curve slope and the method of fairing the loading are also improved. The new results agree within +1 percent with theoretical results believed to be accurate; whereas maximum errors of the original Weissinger seven-point loading (for wings swept back 45°) are approximately 2 and 8 percent for aspect ratios equal to 3 and 10, respectively.
