JEPPESEN & CO., Denver, Colorado / USA Model »CSG-1A« (1965) ***************************************************************** P O C K E T M O D E L 1st picture = 1st Side of the Slide & CALCULATOR SIDE of the Flight Computer: ========================================= The CALCULATOR of the computer consists of a special circular slide rule with 10..100 scales for multiplication and division. The associated third scale is calibrated in hours and minutes. o Time, Ground Speed, Distance Problems o Fuel Consumption Problems o Altimeter Correction o Airspeed Correction Problem o Density Altitude o Drift Correction for Off Course Problems o Conversion Indexes o Common Multiplication and Division o Rate of Climb and Descent 2nd picture = WIND SIDE of the Flight Computer: =============================================== The WIND SIDE of the computer consists of a rotating azimuth and a rectangular grid that slides up and down through the azimuth. The sliding grid has two sides, a low speed and a high speed side (see 2nd picture: lower w. "WAC" / STATUTE Miles and upper w. "SECTIONAL" / STATUTE). The azimuth circle rotates freely and is graduated into 360°. The transparent portion is frosted so that it can be written on with a pencil. o Solution of Wind Vector Triangles, Formulas for Wind Triangle Solution w. TC = True Course WCA = Wind Correction Angle TH = True Heading VAR = Variation DEV = Deviation CH = Compass Heading MC = Magnetic Course CC = Compass Course o Drift on Multiple Headings o Half Scale Wind Triangles o Radius of Action Wind Triangles o Off Course Problems REMARKS: ================================================================= This P O C K E T Flight Computer looks like Model »CSG-2A«, the "NAVIGATOR"-Version, but smaller. Also made of aluminum and it came in a brown leather case with a ( 64 p.) instruction book.
