What is the primary use of the E6B flight computer?

The E6B flight computer is primarily designed for performing navigation calculations. It is a versatile tool used by pilots to solve various aviation-related problems, including calculating groundspeed, wind correction angles, estimated time en route, and course headings.

While it can indeed assist in determining wind direction and speed, this is just one of its many applications. The core functionality of the E6B is its ability to facilitate multiple navigation calculations, integrating factors like wind effects, so that pilots can navigate more effectively and accurately during flight.

In contexts related to fuel consumption or measuring altitude changes, other resources or instruments are typically employed. Therefore, focusing on navigation calculations emphasizes the central role the E6B plays in aiding pilots with navigational tasks, demonstrating its importance in flight planning and real-time navigation.
