1. The E6B flight computer is a form of circular slide rule used in aviation and one of the very few analog calculating devices in widespread use in the .

2. These flight computers are used during flight planning (on the ground before takeoff) to aid in calculating burn, wind correction, time en route, and other items.

3. Manual E6B remain popular with some users and in some environments rather than the electronic because they are lighter, smaller, less prone to break, easy to use one-handed, quicker and do not require electrical power.

4. In the air, the flight computer can be used to calculate ground speed, estimated burn and updated estimated time of arrival. The back is designed for wind vector solutions, ., determining how much the wind is affecting speed and course. They are frequently referred to by the nickname "whiz wheel".

5. Although digital E6Bs are faster to learn initially, many flight schools still require their students to learn on mechanical E6Bs, and for pilot written exams and checkrides pilots are encouraged to bring their mechanical E6Bs with them for necessary calculations.
