Mr. Howard Flanders, who has been the designer of many successful aeroplanes has designed a new ground-speed indicator, which not only shows the speed of the aeroplane relative to the ground but also draws on a map the exact path the aeroplane has followed since leaving the aerodrome. The principle on which the indicator works is very simple. The various accelerations to which the plane is subjected are measured and the resulting speeds recorded. In the concrete form this problem becomes one of considerable difficulty and has hitherto baffled all, and they are many, who have attempted its solution. Mr. Howard Flanders has overcome the difficulties by an ingenious system of gyroscopes and nerve-motors, which eliminate the confusing problems of relative motion which have hitherto formed a chief difficulty. Practically all the mechanism is electrical, and it will be of reasonable size and weight. Of its utility there can be no doubt, as it will enable the pilot to know his position with absolute certainty in fog, clouds, at night, or at any time when location by sight is impossible. The pilot can also find the speed and direction of the wind on the ground where he is about to make a a landing and thus most of the factors that prevent regular aeroplane flights will be eliminated.
