The ID-453/ARN-30 Course Deviation Indicator was located immediately in front of the co-pilot’s control column just above the aircraft's Gyro Magnetic Compass Indicator.
Comprising 2 pointers and 2 ‘Flags’, the Course Indicator enabled the pilot to follow an FM homing transmission to or from its base of origin.
The large Course Selector Knob at the bottom right of the unit rotated the ‘paired’ Course Pointers around the outside dial representing the 360 degrees of the compass. From here the pilot would initially set the course heading.
The ‘floating’ Horizontal and Vertical pointers adjusted up, down and left or right of the central target circle. The Horizontal Pointer indicated the strength of the FM signal being received, deflecting downwards as signal strength decreased.
The Vertical (reciprocal) Pointer centred itself when the Caribou was either flying directly to or away from the transmitting station. Deflection of the pointer indicated the direction of turn (right or left) to stay on course.
The ‘OFF’ Vertical and ‘OFF’ Horizontal Flags disappeared when the FM Homing circuits were functioning properly.
Manufactured by the Aircraft Radio Corp, this original and battle hardened Course Deviation Indicator carries service stamps on its rear casing and the Course Selector Knob is fully functioning.
Combined with an extremely detailed hand crafted and painted 1/72 scale model of the iconic DHC-4 Caribou perched atop the units mango-wood display stand and with a high quality double sided printed and laminated Fact Sheet this original Vietnam War artefact would make an amazing gift for any aviation enthusiast.
