|This pocket-sized, brushed aluminum E6- B is a full function aviation computer. Popular among military pilots, it 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.|
Fully usable, but the wheel is a little stiff to turn, so its hard to get right on a heading or airspeed. Also a little hard to read, but thats a feature of its small size, so not a complaint. In general, I find the cheap cardboard ones a little easier/faster, but Im still a sucker for analogue gadgets like this. One nice feature is that the sliding card is reversible, so you can flip it around for higher-speed wind-triangle calculations. The default side is calibrated up to 270 kt/mph/kph, and the flip side is calibrated up to 700 kt/mph/kph.
