The Behavior of conventional airplanes in situations thought to lead to most crashes /

The tests showed that a present day conventional airplane will fall into a spin when a turn is attemped in a stalled glide, if it has sufficient longitudinal control actually to stall it. All of the airplanes tests had satisfactory stability and control after engine failure in a steep climb, and it is therefore concluded that serious accidents following engine failure in take-off are probably due either to striking the ground while attempting a turn or in falling into a spin from a stalled glide following the engine failure.Simple flight tests were made on ten conventional airplanes for the purpose of determining their action in the following two situations, which are generally thought to precede and lead to a large portion of airplane crashes: (1) In an attempt to stretch the glide in a forced landing, the airplane is stalled; (2) While taking off, particularly if taking off steeply, the engine fails at a low altitude.NACA TN no. 363."February, 1931."The tests showed that a present day conventional airplane will fall into a spin when a turn is attemped in a stalled glide, if it has sufficient longitudinal control actually to stall it.
