APR's Universal Standard Series Wind Triangular & T/S/D E6B pc attributes patent pending Windspeed Cursor Arm. It calculates flight planning and en course navigation requirements. The system consists of high (200 to 700 kts or mi) and low speed slide wind slide speeds of 40 to 270 kts or miles, easy-to-read conversion scales, flush compass ring, and write-in TC to CH boxes. Consists of wind triangle information and low speed slide. The slide has Nautical and Statute rulers for Sectional and WAC plans, common east/west magnetic variation diagrams, wind triangle meanings, real heading and real course options, and a headwind and crosswind element grid. Guidelines to fix for ground speed, WCA, and headings are printed on the pc and make finding out faster and easier. The Time/Speed/Distance pc provides all major navigation computations. The flight planning side of the wind triangle slide shows solution for real course to compass headings in addition to shown examples of east/west magnetic variation. Likewise shown are meanings pertinent to wind triangle problems and diagrams of real heading and real course options. The headwind and crosswind element grid portrays the relative wind angle in a multi-color graphic for precise and simple interpretation. Nautical and Statute scales for Sectional and WAC Graphes are printed on the sides of the slide.
