APR E6-B4T Pocket Size Flight Computer

APR E6-B4T Pocket Size Flight Computer

The Pocket Universal E6-B4T Wind Triangle and Time/Speed/Distance Computer calculates flight planning and essential en route navigation requirements. The unit has write-in TC to CH boxes. The low speed wind slide shows speeds of 40 to 270 knots or miles.

Learning is faster and easier with instructions to solve for ground speed, WCA, and headings printed at the top of the slide.

APR’s Airlearn System Flight Planning Wind Triangle Information 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 two-tone graphic for accurate and easy interpretation. Nautical and statute rulers for Sectional and WAC Charts are on the sides of the slide.

Includes custom case, lifetime anodized aluminum.

Dimension: 3 1/4" x 6 3/8".  Also available in a full size (4 7/8" x 9 5/8") flight computer as the E6-B2D.
