Repeating Compasses


FROM time to time paragraphs appear in the Press on the subject of compasses in aircraft. They usually take the form of a complaint of the inaccuracy of magnetic compasses in general, followed by praise of some invention which is said to surmount all difficulties. The new instrument is often improperly described as a 'gyro-compass'. It is not the purpose of this article to advertise or condemn any of these inventions, but to enable the reader to see in proper perspective the claims which they contain.
