APR's Universal Standard Series Wind Triangle & T/S/D E6B computer system features patent pending Windspeed Cursor Arm. It calculates flight planning and en path navigation demands. The device includes 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. 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 part grid. Directions to resolve for ground speed, WCA, and headings are printed on the computer system and make discovering faster and easier. The Time/Speed/Distance computer system offers all significant navigation computations. The flight planning side of the wind triangle slide shows solution for true course to compass headings as well as illustrated examples of east/west magnetic variation. Likewise shown are meanings relevant to wind triangle issues and diagrams of true heading and true course options. The headwind and crosswind part grid illustrates the relative wind angle in a multi-color graphic for precise and simple analysis. Nautical and Statute scales for Sectional and WAC Charts are printed on the sides of the slide.
