ao FLIGHT JANUARY 6TH, 1944 Flux-gale Compass The gyroscope used for stabilising the compass horizontally is accurately balanced with the aid of a nrcroscope. Magnetic Compass /Utilises EXISTENCE of a new typeiCf compass which has been in use by the U.B.A. Jrfr Forces for some time was revealed recently onlf because one or more of the instruments had fallen mro Nazi hands, but it would not be possible for the enemy to produce and put into volume production during this war a copy that would duplicate the performance of the American device. Perfection of this new compass in the course of sev 4 years of development by engineers of the Eclipse-Pioneer^ Division, Bendix Aviation Corporation, aad named the Pioneer Gyro Flux-Gate Compass, is said tp have met the need for quick-acting, undisturbed azimuth indication in flight, to make the use of a magnetic-compass correction card unnecessary, and to avoid the errors due to precession of the gyro compass. It will have many uses after the war. It combines the north- seeking principle of the mag netic compass with the stabil ising principle of the gyro scope, and, according to W. A. Reichel, engineering director for Eclipse-Pioneer, it will not go off its reading when the aircraft dives or climbs rapidly, lag or over shoot during a turn," nor oscillate or '' hunt'' back an<J forth in rough weather. This, he said, is particularly notice able in the polar regions, where magnetic compasses "go haywire." True signifi cance of the development, which represents a long, for ward step toward mastery of the air lanes, will not be generally realised until the Making final tests for ac curacy of the flux - gate compass.
