Notes on Speed Indicators for Airplanes

There are two dangers which an aviator must guard against by the use of a speed indicator. Too low a speed may lead to stalling; that is, the speed is so low that the weight of the airplane is not sustained, and on the other hand too high a speed may cause excessive stress and possible breakage.
