ABSTRACT:
A hand-held movable airplane model is equipped on an outer face with an outer rotatable donut shaped disc and an inner stationary black circular disc. The outer disc, having compass markings, is rotated by turning a simulated OBS knob to simulate a course card. Indicator needles and flags on the stationary inner disc simulate V.O.R. and Gliode Slope indicators as they would actually appear on an airplane in similar positions and orientations to those of the model as the model is moved over a vertical surface simulating a flight pattern. All needles and flags on the model rotate on pivot pins through the inner disc. Tabs on the underside of each needle and flag are positioned beneath an elasticised band with a high friction surface. The band stretched around the periphery of the inner disc hold all of the needles and flags in place as they are oriented by hand.
