Abstract
This invention provides an inexpensive but accurate mechanical analog computer device for providing information based on the relative positions of two or more indicia bearing members at least one of which is mounted to another of said members for non-rotational orbital movement. More particularly a preferred embodiment of the invention is directed to a visual-mechanical device which simulates ADF and/or VOR navigation such that students and experienced pilots can develop skills at home, and also use the device as a reference tool in actual flight. The device incorporates a disc assembly which revolves or orbits non-rotationally about a beacon representation, driven by a lever which also rotates about the Beacon. The discs and lever have representations of the dials, pointers and windows necessary for unambiguous simulation of ADF and/or VOR navigation without interchange of parts.
