FlightReady E6B Computer

Over 100 aviation functions, conversions, and utilities, including functions that you won't find in any other E6B.

Each function uses the correct scientific formula to ensure accuracy. Other E6B apps rely on rules of thumb that can be up to 10% off. The most comprehensive, accurate, and easiest to use E6B on the App Store.

What is an E6B?

An E6B flight computer is traditionally an analog device resembling a combination slide rule and slide wheel that performs calculations specific to aviation. For example, an E6B can be used to calculate heading and groundspeed after taking into account forecast winds. An E6B is also used to calculate data used for performance planning such as density altitude. Our version goes beyond the analog E6B and even beyond all other E6B apps by including functionality to calculate time, rate and radius of turns, pivotal altitude (great for flight training use), and more.

▸ When selecting a field, any value in the field is automatically selected. Start typing to replace the value. Back button, Clear, and All Clear are still available for editing.
