APR E6-B2D Premier Colored Slide Lock & microset | E6-B2D

APR's E6-B2D flight computer not only incorporates color to help you easily identify your calculations and get off the ground quicker!

The Premier Universal Wind Triangle & T/S/D 5-color computer calculates flight planning and en route navigation requirements. The unit includes 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 charts, typical east/west magnetic variation diagrams, wind triangle definitions, true heading and true course solutions, and a headwind and crosswind component grid.

Instructions to solve for ground speed, WCA, and headings are printed on the computer and make learning faster and easier. The Time/Speed/Distance computer 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. Also displayed are definitions relevant to wind triangle problems and diagrams of true heading and true course solutions.
The headwind and crosswind component grid depicts the relative wind angle in a multi-color graphic for accurate and easy interpretation. Nautical and Statute scales for Sectional and WAC Charts are printed on the sides of the slide.

Included is a 4-color 52-page illustrated Manual along with the "Dead Reckoning Wind Effects Theory Calculations and Vector Diagrams" a Bonus Booklet valued at $9.95. The Computer is made with lifetime anodized aluminum. Embossed Custom vinyl pouch.
DIMENSION: 4 7/8" X 9 5/8"
