New from ASA is the E6B Circular Flight Computer.
Pilots can use the calculator side to perform time, speed, distance, rate, fuel consumption, altitude, airspeed, air temperature, and pressure pattern calculations.
Use the wind side for addition and subtraction problems, as well as solving 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, then wiped clean to allow input for the next problem, according to ASA officials.
The flight computer, priced at $29.95, can be used during flight planning, flight training or studying, and may be used during FAA Knowledge Exams.
