A Study of Blacking Out with Experiments Performed on Single-Seater Aeroplanes

The design of the aeroplane is constantly changing but new designs are drawn with regard to increasing the efficiency of the machine. Already we have reached a stage at which, on account of "blacking out", the efficiency of the machine, under certain conditions at least, is greater than that of the pilot controlling it. This deficiency on the part of the pilot is due to the force of the acceleration acting on him during these manoeuvres. One cannot remove these forces but their effect can be rendered void by changing their direction of application. This, unfortunately involves revolution in the design of the aeroplane but it can be done. If, then, the future of the aeroplane is to advance, future designs of the aeroplane must be drawn with regard to the efficiency of the pilot as well as to that of the machine itself
