APR's Pocket Series Wind Triangle & T/S/D E6B computer system attributes patent pending Windspeed Cursor Arm. It determines air travel planning and en route navigation requirements. The unit includes high (200 to 700 kts or mi) and reduced speed slide wind slide speeds of 40 to 270 kts or miles, easy-to-read conversion scales, slide lock, flush compass ring, and write-in TC to CH boxes. The slide has Nautical and Statute rulers for Sectional and WAC graphes, typical east/west magnetic variation diagrams, wind triangle meanings, real going and real course solutions, and a headwind and crosswind element grid. Instructions to solve for ground speed, WCA, and headings are printed on the computer system and make finding out faster and simpler. The Time/Speed/Distance computer system offers all major navigation computations. The air travel planning side of the wind triangle slide reveals solution for real course to compass headings in addition to shown examples of east/west magnetic variation. Also displayed are meanings appropriate to wind triangle issues and diagrams of real going and real course solutions. The headwind and crosswind element grid portrays the relative wind angle in a multi-color graphic for precise and easy interpretation. Nautical and Statute scales for Sectional and WAC Graphes are printed on the sides of the slide.
