great unit
by A Customer from Windsor CO USA 

Pros: works as advertized
Cons: a little big
Review: If I had seen this prior to purchase, I would have gotten the one smaller in size, but, it's a great unit. Be even better with a good instruction book.

nice design
by A Customer from NH 

Pros: well planned design
Cons: a little awkward to rotate the wheels
Review: I like the design of the Jepp CR-2 that I have, but it is too small to read easily. The CR-3 is large enough that it is much easier to read. This computer has more features than the E-6B, and the circular wind-drift calculator is a nice method that takes less turning and sliding of wheels.

The 'Old School' CR Whiz Wheel tech will never die
by Old Aeronaut from NJ 

Pros: Considers everything regardless of the aircraft type (high performance and low performance aircraft)
Cons: Some fine print - but you get used to it...
Review: I learned flight planing with the old Jep Avstar electronic E6-B in Embry-Riddle back in the '80's. When I learned to use the CR Wheel, the Avstar was thrown in to the back of the desk draw and never used again. In my opinion - I don't know why the E6-B was never retired when the CR was introduced... It factors in Compressibility and Ram Rise - which other computers don't - electronic or otherwise, and it's more portable. The 'Wind Side' is just plain stupid-easy. It's nothing more than a 360 cross wind correction chart.

Great Idea....hard to read.
by Charles from Woodbury MN USA 

Review: The CR-3 has all the functionality you need but the Black print and Gray background make the wiz wheel difficult to read in anything but good lighting conditions.

by Robert Morris from Austin TX USA 
Review: CFII and have not had a chance to use it to the full extent.
It needs to inclulde the work book to, that I picked up, to really make it useful.
Worth the money and time to learn to use it.
I have passed it on to my students for their imformation.

circular computer
by Mike from IL USA 

Review: The computer is great but the instruction booklet is bad. You download it from the website. It is hard to read some of the answers. The examples are not clear and it is difficult understand the exactly what you are doing after you have done it. The computer is a great back up or good to use for flight planning, but they need to work on the manual.

by JO from Pine River MN USA 
Review: Hi! Not quite ready to give helpful comments. Can say for sure that your products put to shame the materials I studied back in 1950 and 1960 to pass all my FAA tests up to and including II (instrument instructor) glider and sea plane. The presentation is overwhealming and may I say beautiful? A map and drawings of approahes or flite plans have always been my favorite art. No, I am not flying presently-I am 82 years old and not quite rich enuf for modern day costs,I got a plane and an instructor for under 50 dollars an hour back then and bought myself an 85 horse Piper Cub to build up time and distance cheaply. But,I still have 20\20 eyesight after cateract surgery,a BP of 125/70.a pulse of 72 and I can ride a bicycle. Keep flying all you guys and yes I will comment on the flite computers. Right now I still like my old E6B because I know it but circular makes better sense and efficiency. JO

Excellent tool
by Dave Howard CFI, CFII, MEI from Arizona 

Pros: smaller than E6B, easy to read, good quality materials and construction.
Cons: too big to carry in a pocket
Review: I have used one of these for years, even before I learned to fly! Excellent for figuring trip time, fuel mileage, currency conversions, etc. When I started flying, I bought a metal E6B, but kept coming back to the CR3 because it is more compact and solves all the same problems. Wind solutions, crosswind components, time-speed-distance-fuel, etc. Other handy solutions: Off course correction, feet-per-mile to feet-per-minute, feet-per-minute to match glide-slope, time-to-station/distance-to-station, distance flown on an arc, CG shift, etc. I see student pilot using electronic flight computers, electronic calculators, and old fasnioned long-hand math taking much more time to solve problems that this will solve simply and quickly. All I can say is if you have one of these and know how to use it, your life as a pilot is much easier.

ADF intercept solution
by Phil Hill from Fairbanks, AK 

Pros: Simple, one-handed operation and no batteries for in-flight use. cr-5 is perfect shirt pocket size.
Cons: OK, I have to use reading glasses to see the cr-5 but the cr-3 is 'that much' too big to carry in a pocket.
Review: I absolutely love this product! I am currently a student studying for my commercial exam and I've gone to using this computer exclusively instead of the E6-B. I was introduced to this device by my instructor who is a 30 year veteran J-3 cub bush pilot here in Alaska who swears by the cr-5: "Simple one-handed operation for any problem during flight and no batteries needed in extreme cold!"

As per your suggestion to write to you for additional uses of this computer, I learned how to use it along with the ADF indicator to intercept bearings (there was no ADF examples in the instruction book). The wind side (blue radials on cr-5) is a perfect illustration of one's position in the air as if looking down from above. Used as a compass rose, place the present heading under "TC" and observe the desired magnetic bearing radial to be intercepted. Count 30 degrees from either side of that bearing to get the final intercept bearings either left or right depending on your position from the station, then count back from either one of those by each blue (10 degree)radial to get the number of degrees left or right needed to turn to achieve the desired intercept bearing.

Example: MH: 035. Desired bearing to intercept: 240. Two headings possible to intercept 240 from left or right @ 30 degrees: 210 or 270. Either turn left (if station is to the left) 125 degrees to intercept, or turn right (if station is to the right)175 degrees to intercept. Perfect solution for study work when an ADF indicator is not handy.

I know that GPS technology is sweeping the nation, but the FAA is still requiring ADF and VOR knowledge on the tests.

If my above description doesn't make sense, please write me at my E-mail address provided below. I'm always open to learning more and learning from mistakes(on the ground, lol)!

Thank you Jeppensen!
