PRINCIPLES OF FLIGHT

The first part of the film demonstrates with excellent action shots the principles of gliding. Laboratory tests on full sized airplanes are made in huge wind tunnels. Scale models in small wind tunnels are used to study flight conditions. We see the controls of an airplane as hands work feet in the air; then animated diagrams are given of the work of the rudder, the elevators, and the stabilizer. That ailerons cause the plane to bank at the turns is also demonstrated.
