THEORY OF FLIGHT 7 equivalents. The horizontal projection A C of a plane A B (Fig. 5) increases A C with a decrease in the angle of inci- dence, while its vertical projection A D decreases A D', and vice versa. The lift is proportional to the horizontal equivalent, the drift to … angle, the greater the Fig. 5 drift; but, on the other hand, the increase of the angle causes the plane to engage more air, and as in reality it is the product of the two that must count, that is, the surface of the plane and the mass of air, an increase of angle means an increase of lift besides…
