Jeppesen vintage 3-way slide course protractor graphic computer Model CSG-2P, with pouch / case. The top wheel turns to provide computations for density altitude and crosswind component, and to obtain TAS. The slide graph lists directions to use calibrated airspeed and pressure altitude to obtain F factor then multiple F Factor by TAX obtained with computer to obtain TAX corrected for compressibility. Designed by Jeppesen & Co., of Denver Colorado.
Measures approx. 9-1/2 inches long, 5 inches wide. Used but in very good condition; wheel/slide works. Some discoloration to the cover.
