This manual E6B Circular Flight Computer takes the rotating wizwheel of a standard E6B and increases the size for ease of use and readability. The calculator side of the computer uses conventional slide rule procedures to solve 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.
The wind side of the computer provides a graphic method of solving problems and displaying the answers in a useful form. Use the wind side for simple addition and subtraction problems and also to solve for true wind, winds in flight, true course and ground speed, true heading and true airspeed, and off-course correction calculations. The matte finish on the wind side of the calculator can be marked with a pencil during use, and easily wiped clean to allow input for the next problem.
The E6B Circular Flight Computer is a great tool to use during flight planning, flight training or studying, and may be used during FAA written knowledge exams. Measures 15cm in diameter.
