Abstract
The wing areas and corresponding wing loadings giving best average cross country speeds for four different types of wing sections drag polar are determined and the cross country speeds are compared.... The results show that, in contrast to assumptions made in some former papers, the wing section has a significant effect on the optimum wing area (or aspect ratio). Furthermore, the optimal wing section characteristics....seem to be significantly dependent on the competition weather.
