A used Air Navigation computer slide rule in good overall condition and in case. Fully working condition. From the estate of a USAAC navigator.
This rule represents a very important class of slide rules - those used for air navigation. While flying, the direction that an aircraft follows over the ground is a function of its air speed and heading and the wind speed and direction. In addition to allowing a pilot to calculate what his/her resulting track over the ground is, this rule also enables other important calculations to be carried out such as the relation between indicated airspeed and true air speed.
