Course and Distance computor, Mk.IIA

This calculator was used in aircraft to solve velocity triangle problems involving wind values from drift observations, in order to determine the ground speed and track of the aircraft. On the reverse side of the calculator there is a circular slide rule for time and distance calculations.

This form of calculator was superceded by the Dalton Navigational Computer, R. A. F. Mark III.
