APR E6-B9 Classic Universal Airlearn Pilot Flight Computer

APR E6-B9 Classic Universal Airlearn Pilot Flight Computer

The Pocket Universal E6-B9 Wind Triangle and Time/Speed/Distance Computer calculates flight planning and essential en route navigation requirements. The unit has write-in TC to CH. The low speed wind slide shows speeds of 40 to 270 kts or miles.

Learning is faster and easier with illustrated graphic instructions printed at the top of the slide for solving Ground Speed, and WCA, and Headings.

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 on the slide 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. Meets FAA AC 60-8 requirements.

APR has manufactured military and all its general aviation products in the U.S.A. for over 50 years.

Included is a 4-color 52-page illustrated Manual along with a Bonus Booklet “Dead Reckoning Wind Effects Theory Calculations and Vector Diagrams” valued at $9.95. The computer is made with lifetime anodized aluminum. Embossed Custom case.
