This determination of the position of the aircraft may be derived from what is commonly known as the wind triangle in which vectors may be plotted that represent the selected true course, wind, and true air speed of the aircraft. In the basic form of air navigation known as dead reckoning, the instantaneous position of the aircraft being so navigated is determined from a continuous plot of the track and average ground speed of the aircraft with the elapsed time from a known departure and/or intermediate check point or turning position along the track. A trig-log scale-inscribed disc is interposed between the relative bearing-cursor assembly disc and the calculator-lower disc, and a compass indicator disc is mounted on the relative bearing-cursor assembly disc. A computer-wind side includes a relative bearing-cursor assembly disc that is laminated to the reverse side of the calculator side-lower disc and is inscribed with ''''TRUE AIR SPEED/GROUND SPEED'''' and radially-aligned wind drift and course indices at the 180* relative bearing value with a radial cursor line extending between the wind drift and true air speed/ground speed indices.
