The E6B flight computer, nicknamed the “whiz wheel” or “prayer wheel”, is a form of circular Manual E6Bs/CRP-1s remain popular with some users and in some environments rather than the electronic ones because they are lighter, smaller. ASA-E6B-CIRC . Your ASA E6-B Circular Flight Computer has two main parts: a circular slide . Your Approved Flight Manual lists fuel capacity in U.S. gallons.

On the positive side, It means any number on the scale can represent any order of magnitude of that number. This nifty contraption has both a computer and wind side.
Mastering the Mechanical E6B in 20 Minutes | The Blog of Michael Soroka
Align the distance you traveled on Scale A with the time you traveled on either Scale B for minutes or Scale C for hours. Did this article help you? Typically, time is though of in seconds, minutes, and hours rather than percentage of hours 1: Where should we fly today?
Subscribe to Clayviation Get Clayviation content delivered to your inbox weekly! Rotate the azimuth plate until your desired course true course is aligned under the True Index mark. Fliight on May 19, at Find the leg time on either Scale B for minutes Scale C for hours. The wind side uses a rotating disc, called the azimuth plate, marked with degree compass headings, and a sliding grid with speed and angle markings to find wind correction angle, ground speed, true heading, and most favorable winds.
The second tick mark to the right of “35” may represent 3. The grid is visible through the transparent part of the wheel. The base name “E-6” was fairly arbitrary, as there were no standards for stock numbering at the time.
All articles with unsourced statements Articles with unsourced statements from March In addition, computer programs to emulate the flight computer functions are also available, both for computers and smartphones.

The changes included moving the “10” mark to the top instead of the original “60”. It was helpful for me. The calculator side of the flight computer is constructed so that any relationship, or ratio, between a number on the outer scale and a number on the inner scale will remain constant for all other numbers on both scales.
Our estimated ground speed of reads under the center hole and the wind correction angle of 8 is the number of units left or right of the center line that the pencil mark rests. Army Air Corps decided the endless belt computer cost too much to manufacture, so later in Dalton morphed it to a simple, rigid, flat wind slide, with his old Model B circular slide rule included on the reverse.
Find the wind correction angle by counting the units between the pencil mark and the centerline. These are commonly available on collectible auction web sites. How much fuel will a Cessna burn on an 8 minute leg with a fuel burn of 5.
The wheel on the back of the calculator is used for calculating the effects of wind on cruise flight. If you know ground speed between checkpoints and the wind correction angle, the process can be followed backwards to find actual wind speed and direction while flying. Consider that a direct headwind will simply slow us down, and a direct tailwind will speed us up. We can determine the wind correction as follows hint: Tips Electronic flight computers can also provide this information but require batteries which could fail during a flight.
Like leg time, the pointer and scales you use will be different if you are working with seconds, minutes, or hours.
Add or subtract the wind correction angle from the true course to find true heading. It can also be used for multiplication and division. Complete the domputer by use of the formulas. This article has also been viewedtimes.
A typical calculation done by this wheel answers the question: This is the way it has always been fligth. Aviation remains one of the few places that the slide rule still is in widespread use. In this example, this will mean that the mark will be left of the center-line. Take, for instance, cross country flight planning.
How to Use a Graphic Flight Computer to Find Ground Speed and True Heading
The B and C scale must be good friends. Scale Values The numbers on the outer and inner scales represent multiples of 10 of the values shown. Once the wheel is positioned to represent a fllght fixed ratio for example, pounds of fuel per hourthe rest of the wheel can be consulted to utilize that same ratio in a problem for example, how many pounds of fuel for a 2.
Cockpits were illuminated this way coomputer night. Always take it with you on your flight training. Already answered Not a question Bad question Other. The arcs represent the wind velocity in knots. First I will define the scales and the pointers, and then I will show you how to put them into action!
Then find the number you want to multiply by on Scale B. Add or subtract magnetic variation and compass deviation to find the compass heading to be flown.
When flying from one point to another, you are subject to being pushed by the river of air similar tuhorial being pushed downstream by water. Place TC under True Index.
I still keep one in my flight bag, even with the airlines.
