Description

The E6B Circular Flight Computer combines high-quality construction with easy- to-read lettering to deliver the most efficient, accurate, and convenient manual flight computer availalble. Perform multiple calculations ranging from basic arithmetic and flight planning problems to complex in-flight computations. The calculator side of the computer uses conventional slide rule procedures to solve for multiplication, division, and unit conversion and employs scales for performing time, speed, distance, rate, fuel consumption, altitude, airspeed, air temperature, and pressure pattern calculations. The wind side of the computer provides a graphic method of solving problems and displaying the answers in a useful form. Use the wind side for simple addition and subraction problems and also to solve for true wind, winds in flight, true course and ground speed, true heading and true airspeed, and off-course correction calculations. The matte finish on the wind side of the calculator can be marked with a pencil during use, and easly wiped clean to allow input for the next problem. The E6B Circular Flight Computer is a great tool to use during flight planning, flight training or studying, and may be used during FAA written knowledge exams. Pilots flying faster aircraft at higher altitudes will find this computer useful in gaining insight to the external atmospheric conditions and the effects they have on in-flight performance.

Really nice

    • Very similar to the good ol' Jeppesen CR-5
Very similar to the (no longer available) Jeppesen CR-5 - probably the closest I have found so far: same size, similar design and build quality (the only minor difference I could notice is the location of the mach number window...) - in fact (subjective impression), I'd say this ASA model is even more readable (perhaps due to the choice of color) than the original CR-5. The only downsides are that: i) it shouldn't have been named an E6-B - as it can be confused with the traditional E6-B design (see the excellent aluminium ASAs Color E6B Flight Computer also available on Amazon); and ii) this is probably not your best choice if you are a student pilot - as you should probably pick the aforementioned traditional aluminum E6-B which is IMHO more intuitive to use (moreover your basic trainer aircraft won't be flying at the high mach numbers for which the CR design gives more accurate answers, and said traditional E6-B design is what is usually referenced in private pilot ground school material - and written tests). That said, I love this circular flight computers for geeky reasons and for its more convenient (IMHO) form factor. ... show more

    • I like the colors, it’s built well, and it’s almost accurate.
I like the colors, it’s built well, and it’s almost accurate. The fact that it was off, even by a little bit, was enough to make me return it. If they can redo this and get the ratio right, I would use it/buy it again.

    • Pretty solid and well documented
This E6-B computer is pretty well constructed and the scales are well printed (although it may look that their precision is a bit off it is actually not). The leather case is well made and it looks cool and the manual is easy to read and follow. I'm happy with my purchase.

    • Good Quality
Great quality and is what I expected. As seen in the picture looks (and is) a little bit better than the competition, concerning quality.

    • More feature-ful than E6B. Not accurate for *no good reason*
The main slide rule is just slightly misprinted. Do something basic like multiplying two numbers together. You hope that if you multiply by 2 then 80 should be straight across from 40. It's not. its off by a little more than the width of the printed line. If you didn't know any better, you might think that 30 x 3 was 91. However, as far as the features, go, I find it more useful than the E6B. Despite being slightly inaccurate, I still use it. ... show more
