An aviation training aid to facilitate the learning of instrument flying techniques. Primarily designed for the application of wind drift problems associated with tracking a straight course over the ground which making an NDB (non-directional beacon) instrument landing approach. This device includes a model airplane that rotates freely through 360 degrees with a compass azimuth card pointer and ADF (automatic direction finding) card rotating on the same axis. The compass azimuth card is controlled by a vertical shaft or handle placed through the center axis, enabling the user to keep the pointer oriented to designated north while reading the airplane's heading in the cutout provided in the airplane's nose (this is the simulated magnetic heading of the aircraft). The wingtip and reciprocal bearings are also provided through cutouts string, simulating the direct bearing to the NDB radio station is also connected from the center post to the designated NDB radio station (push pin). The ADF card that revolves on top of the airplane gives a true presentation of the ADF (automatic direction finding) bearing while simulating a landing approach.
