This Circular Flight Computer ( 6” diameter ) does everthing the slide graphic type E6-B do, and you can also use the wind side to solve problem for true wind, true course, wind in flight and speed issues.
All printings are sandwich printed between two pieces of plastic so that the numbers/printings will never rub off during your long time usage.
This Circular Flight Computer will help you solve multiple calculations such as flight planning, basic arithmetic or complex in aviation computations.
The calculator side are workable for multiplication, division, and unit conversion and employs scales for performing time, speed, distance, rate, fuel consumption, altitude, airspeed, air temperature, and pressure pattern calculations.
