- Summary:
- A large range between the maximum and minimum speeds of an airplane is of undisputed value, either to permit safe landings in small fields with the medium or slow speed machine, or to permit landing at all with very high speed machines. The factors that limit the maximum speed are well understood, but rather strangely the limiting factors of the minimum speed have seldom been recognized. The whole question of minimum speed has usually been settled by the statement that the wings have reached the point of maximum lift, whereas there are very few airplanes that can be flown at, or beyond, this point, and a great many that cannot reach within 5 degrees of it. Because of this general misunderstanding of the principles of flight at low speed there are a large number of machines that could be made to fly several miles slower than at present by slight modifications.
