Use your flight computer to solve these practice problems answers are located below. The front side is used for everything else.

Look at the “NAUT” index arrow on the outer scale to determine 87 kt. Dalton felt that it was a rushed design, and wanted to create something more accurate, easier to use, and able to handle higher flight speeds.

Clay on May 19, at The wind correction angle is determined by matching how far right or left the pencil mark is from the hole, to the wind correction angle portion of the slide’s grid.

The directions for the most common use of the wind side are printed right at the top. Thus you may use it for textbook exercises, but when flying, think magnetic. In he put a double-drift diagram on its reverse to create what the U.

It is well designed to assist you in solving the planing and navigating problems associated with flying. Subscribe to Clayviation Get Clayviation content delivered to your inbox weekly! If your ground speed isthen call Guiness, speed racer.

Find the leg time on either Scale B for minutes Scale C for hours. The grid is visible through the transparent part of the wheel. The nice thing about the mechanical E6B for these types of problems is that it does not have to be rotated again to calculate different legs if the ground speed is unchanged. Like leg time, the pointer and scales you use will be different if you are working with seconds, minutes, or hours.


The mathematical formulas that equate to the results of the flight computer wind calculator are as follows:. Which one you use is a personal preference — both are easy and accurate in their own way. The designation “E-6B” was officially marked on the device only for a couple of years. This will affect our ground speed as well as our heading. Different pointers will give you outputs in different units or bases.

How much fuel will a Cessna burn on an 8 minute leg with a fuel burn of 5. What descent rate will you need? Rather than outline each one, I have made a collage of sorts to highlight a couple:.

If you pencil mark falls to the left of the centerline, subtract the value from your True Course to get your True Heading. It was hugely popular with both the military and the airlines.

The reality compiter the E6B is that, although it is simple to operate, it is not an intuitive piece of equipment to learn. C to F conversion is a lifesaver for PAs. The center hole marks our ground speed and your pencil mark shows our left or right wind correction angle in degrees. The words in quotations above are the first words printed in the 50 page instruction manual that came with my E6B.

Before you start a leg time problem, you must first ask yourself: One common feature of all slide rules, the E6B included, is that they do not account for order of magnitude.

The wind direction of is under the True Index and the wind speed of 20 is marked up from the center hole. The changes included moving the “10” mark to the top instead of the original “60”.


These scales are named and highlighted below:.

E6B – Wikipedia

Pivots of metal models metal with plastic grommet will wear out the plastic grommet prematurely, causing the wheels to spin freely. Pointing straight across the river will cause you to drift downstream. The rate pointer will point to your ground speed. For secondsuse the Second pointer and Scale B. The advantages of this method are You convert only one true direction to magnetic, not two.

When flying, you should always think magnetic, not true. You can either round your answer up or down 9. How long will it take to fly nm at a groundspeed of kts?

First I will define the scales and the pointers, and then I will show you how to put them into action!

Also, I learnt how to use the E6B in 30 minutes, close enough to 20! Then a pencil mark is made just above the hole, at a distance representing the wind speed D away from the hole. The only thing keeping pilots from buying a mechanical E6B is the learning curve.

In the air, the flight computer can be used to calculate ground speed, estimated fuel burn manuual updated estimated time of arrival. All articles with unsourced statements Articles with unsourced statements from March Very clear and to the point.

But notice the center of the circle is clear. Read your answer directly above this number on Scale A.

The A scale is the outer scale, while the B and C scale stick together on the inner disc. This is especially true for those of us who did not grow up in the slide rule generation; as that is exactly what the E6B is, a slide rule.
