The essential E6B emulator. Calculate TAS, Ground Speed, Wind Correction Angle, and more.
The E6B flight computer, often called the 'Whiz Wheel', is an iconic analog circular slide rule used by pilots since the 1930s. This digital E6B emulator flawlessly replicates its core capabilities, letting you calculate True Airspeed, Wind Correction Angles, and Fuel Endurance instantly.
A major function of the E6B is solving the Wind Triangle. The vector math combines your Aircraft's True Airspeed and heading with the wind's speed and direction to find your actual track over the ground (Ground Speed) and the compensatory Heading (Wind Correction Angle).
While E6B flight computer apps are perfect for pre-flight planning, always remember that forecast winds aloft are just predictions. Constantly cross-check your ground speed in the cockpit to ensure your fuel endurance remains safe.
Density altitude is calculated by aligning the pressure altitude with the outside air temperature on the E6B's sliding scale. Our digital E6B does this automatically within the TAS tab.
It calculates time, speed, distance, fuel consumption, wind correction angles, density altitude, true airspeed, and Mach numbers. It is an indispensable tool for student pilots and flight planning.
Yes! While modern aircraft have advanced FMS and GPS, the E6B remains a fundamental training requirement for obtaining a Private Pilot License (PPL) and commercial certificates.
