Report on operations given by Fred Harmon of the Harmon Flying School at Ballinger, Texas. The report states that there are 210 students per class, 110 mechanics for 94 airplanes with 45 women who start at $65 per month. Women took night school course, 2 hours per night, 4 nights a week, while paid $1 per night, for 30 days. The women mechanics proved very steady, very capable, and efficient.

A preliminary study of pitching-moment data on tapered wings indicated that excellent agreement with test data was obtained by locating the quarter-chord point of the average chord on the average quarter-chord point of the semispan. The study was therefore extended to include most of the available data on tapered-wing models tested by the NACA.

"A graphical method is described for finding the shape (camber and twist) of an airfoil having an arbitrary distribution of lift. The method consists in replacing the lifting surface and its wake with an equivalent arrangement of vortices and in finding the associated vertical velocities. By division of the vortex pattern into circular strips concentric about the downwash point instead of into the usual rectangular strips, the lifting surface is reduced for each downwash point to an equivalent loaded line for which the induced velocity is readily computed" (p. 543).
