APR's Premier Series Universal E6B Wind Triangle & T/S/D 4-color computer system features patent pending Windspeed Cursor Arm. It calculates flight planning and en course navigation requirements. The unit includes high (200 to 700 kts or mi) and low speed slide wind slide speeds of 40 to 270 kts or miles, color-coded 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, common east/west magnetic variation diagrams, wind triangle meanings, true heading and true course options, and a headwind and crosswind component grid. Instructions to solve for ground speed, WCA, and headings are printed on the computer system and make learning faster and much easier. The Time/Speed/Distance computer system provides all major navigation computations. The flight planning side of the wind triangle slide shows formulae for true course to compass headings as well as illustrated examples of east/west magnetic variation. Likewise shown are meanings appropriate to wind triangle troubles and diagrams of true heading and true course options. The headwind and crosswind component grid shows the relative wind angle in a multi-color graphic for precise and simple analysis. Nautical and Statute scales for Sectional and WAC Graphes are printed on the sides of the slide.
