APR’s Student Series E6B Pilot Wind Triangle & T/S/D Navigation Computer quickly tells you groundspeed, wind correction angle, and magnetic heading. The APR E6-B8 is the only student computer made entirely of plastic. Competitors' student models are made of cardboard or paper; there is no similar computer on the market!

The E6-B8 calculates all necessary flight planning and en route navigation requirements. Easy-to-read scales are user-friendly and allow for quick, accurate reading. Instructions printed on the computer 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.

Unlike our competitors’ student computers which are made with paper, composite, or fiber board, APR’s student computers are made with PVC Plastic.
