to the Arctic and from sea level to the stratosphere. Whether used in the air or on the ground, everything we make must be precise and rugged. [[left margin]]AUTOMATIC RADIO COMPASS[[/left margin]] The Automatic Radio Compass is one of the best known and most widely used of the many pieces of aircraft radio equipment which we manufacture. You have perhaps noticed on planes or pictures of planes the oval shaped, streamlined object about a foot long and nine inches high that is mounted on the fuselage. This is the "loop housing" within which is located the "loop antenna" which is an essential part of the Automatic Radio Compass. Practically every commercial passenger plane in this country has such a compass installed in it. A majority of the bombers of the Allied Armed Forces also carry this equipment. With a Radio Compass the pilot of a plane can find the direction in which a radio station is located and can fly toward the station. If for example, a bomber on patrol out over the Atlantic wanted to reach the Naval Base in Norfolk, Virginia, he would tune in on a Norfolk broadcasting station. An indicator on the plane's instrument panel that is connected to the Automatic Radio Compass would immediately tell him in what direction to fly in order to get to Norfolk. If the pilot were lost, he could tune in on two radio stations whose location he knew and determine where they were located in relation to his plane. He could then draw intersecting lines on a map and tell exactly where he was. It is a very common experience of pilots in combat to lose track of their location in the excitement of battle. When this happens, the pilot must depend on the Radio Compass to get back home. If the compass fails, the pilot fails.

This unit consists of a transmitter and a receiver combined in a very compact metal cabinet. It is used in commercial passenger planes and in Army transport planes which fly to all parts of the world carrying badly needed supplies to our Armed Forces. The pilot of a plane uses the "RTA" to maintain communications which ground stations along the route he is flying. It is as if he had a telephone installed in his plane. With this equipment he can talk to ground stations along his route and find out if there 7 [[stamp]]BENDIX RADIO[[/stamp]]
