Digital E6B Flight Computer
A mobile-friendly digital version of the E6B “whiz wheel” — the circular slide rule pilots have used for flight planning since World War II. Eight tabs cover all the core E6B functions: time-speed-distance, fuel planning, true airspeed, wind correction, density altitude, altitude conversions, unit conversions, and off-course correction.

About the E6B Flight Computer
The E6B has been used by pilots since World War II. Originally a hand-held circular slide rule, it solves problems in time-speed-distance, fuel planning, wind correction, density altitude, and more. This digital version replicates all of its core functions in a mobile-friendly interface.
Student pilots studying for the FAA Private Pilot knowledge exam will find every E6B-type question on the exam covered by the tabs above. Many flight schools still require learning the physical E6B first — this tool helps you verify your answers.
