This pocket-sized, Brushed aluminum E6-B is a full function aviation computer. Popular among military pilots, The E6-B Micro Flight Computer from ASA features a high-speed and low-speed wind correction slide, high-speed compressibility table, and instruction manual.
Micro E6-B performs all the standard manual flight computer functions, and it conveniently fits in a shirt pocket or glove box.
Many instructors require that their students learn navigational computing on the old-fashioned E6B-type flight computers before they switch to the electronic calculator type. Why? Because the electronic versions just can't demonstrate wind correction calculations as well as these E6B's can. They also work without batteries!
