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. A Pilots Guide on How to use the E6B Flight Computer by lriccc in Types > Instruction manuals. E6B Flight Computer Instructions. Instructions for the E6B Flight Computer. ASA’s E6-B features a wind component grid and comprehensive crosswind correction.

Airplan Flight Equipment Ltd. The arcs represent flitht wind velocity in knots. Landing in this situation is like having a kt. The wind direction of is under the True Index and the wind speed of 20 is marked up from the center hole. Electronic versions are also produced, resembling calculatorsrather than manual slide rules.

E6B Flight Computer Instructions

Believe it or not, a mechanical E6B is actually faster at making calculations, and can populate a navigation log faster than its electronic competition. Check out our Products Or browse all our options in our online store. Remember, the units you use must be equivalent, i. At kts ground flighh, how long will it take you to travel between two checkpoints that are 18nm apart? In aviation, the same compuuter applies.

Convert mph to knots. Each one of these three skill groups require a different technique to perform and can be practiced independent of each other.

This coupled with the fact that a mechanical Eb6 requires no batteries, is essentially indestructible, and looks a lot cooler than a electronic E6B means that the mechanical e6B is here to stay. Now slide the metal slider so that the pencil mark you made lines up with your true air speed.


S Army Air Corpsbefore its reorganization in June From this point, move horizontally to the left margin to determine a headwind component of 26 kt. The ease of use of electronic calculators means typical flight training literature [1] does not cover the use of calculators or computers at all. V gV a and V w are consistent units of mankal. Thanks so much for putting this together.

Because this is a base 60 system, the multiplication pointer wont work for most problems. Plus, the good old metal one will never get low on batteries.

C to F conversion is a lifesaver for PAs. The first tick mark to the right of “10” may represent Enter your email below to receive notifications as soon as new posts are published! First I will define the scales and the pointers, and then I will show you how to put them into action! After the mark is made, the wheel is turned so that the course A is now selected at the top 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.

Read GS under Grommet. One common feature of all slide rules, the E6B included, is that they do not account for order of magnitude.

The directions for the most common use of the wind side are printed right at the top. Different pointers will give you outputs in different units or bases. The advantages of this method are You convert only one true direction to magnetic, not two. Before you start a leg time problem, you must first ask yourself: Clay on May 19, at Like the flip side, it also has a rotating scale where you match one number against another. On the inner scale, minutes may be translated to hours and minutes by reference to the hour scale, which is below and inside the inner scale.


In this example, this will mean that the mark will be left of the center-line. The E6B flight computernicknamed the “whiz wheel” or ” prayer wheel “, is a form of circular slide rule used in aviation and one of the very few analog calculating devices in widespread [ citation needed ] use in the 21st century.

Once the wheel is positioned to represent a certain 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. Just like on the flight computer, the ring is aligned with the air temperature and the pressure altitude, allowing the true airspeed TAS to be read at the needle.

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.

To find crab angle and groundspeed adjusted for wind, you will need to flip the E6B over to the backside. Then find the number you want to multiply by on Scale B.

On the side margins of the card are mileage scales for sectional charts. Flught, so now you are familiar with the three different scales on the E6B and the three different pointers.

Mark Wind Dot up from Grommet. It is well designed to assist you in solving the planing and navigating problems associated with flying.
