outer ring the pilot can find how far the aircraft will travel in any given number of minutes. Looking at the inner ring for minutes traveled and the distance traveled will be above it on the outer ring. This can also be done backwards to find the amount of time the aircraft will take to travel a given number of nautical miles. On the main body of the flight computer it will find the wind component grid, which it will use to find how much crosswind the aircraft will actually have to correct for.
57:, but many professional pilots still carry and use flight computers. They are used during flight planning (on the ground before takeoff) to aid in calculating fuel burn, wind correction, time en route, and other items. In the air, the flight computer can be used to calculate ground speed, estimated fuel burn and updated estimated time of arrival. The back is designed for wind correction calculations, i.e., determining how much the wind is affecting one's speed and course.

The crosswind component is the amount of crosswind in knots that is being applied to the airframe and can be less than the actual speed of the wind because of the angle. Below that the pilot will find a grid called crosswind correction, this grid shows the difference the pilot needs to correct for

One of the most useful parts of the E6B, is the technique of finding distance over time. Take the number 60 on the inner circle which usually has an arrow, and sometimes says rate on it. 60 is used in reference to the number of minutes in an hour, by placing the 60 on the airspeed in knots, on the

Another very useful part is the conversion scale on the front outer circle, which helps convert between
Fahrenheit and Celsius. The back of the E6B is used to find ground speed and determine how much wind correction it needs.
