ASA CX-3 Flight Computer – Advanced Electronic E6B for Accurate Flight Planning and FAA Exam Preparation

I bought this and the sporty's flight computer to compare. I found this one easier to use and much easier to see. Even with my readers it's not easy to see the fine print under each key on the sporty's version. It just made more sense using this one also. One single key does unit conversions and will do so for whatever you are currently looking at. One button only. Sporty's has a different conversion button for each unit designation and you must read very small print under each small key to get to the correct one. The ASA version has simple back space button also if you made an incorrect entry. Super easy. I'm sure there's a way on the sporty's version too but I didn't readily see how to do that in several minutes of using it....what's that tell ya? The COLORED screen show you a green = sign to show this is a calculated field from the numbers you entered. Hence sometimes you see a number you weren't even looking for but because you entered enough data fields it displays and = sign and ALL the related fields it figured out. It takes a bit of time to determine what screen is used for each problem you are looking to solve. For instance endurance will likely be in the 'fuel' category etc. One thing some have complained about is there's no way to clear the computer without removing the battery. I too had a problem it was remembering data entries I didn't want it to so it could possibly give me the wrong answer. But this is because it's trying to show you ALL the possible answers per your entires and carry them over to relevant other screens. However it's very easy to simply start at the top of the screen hit '0' then 'enter' then simply repeat hitting those two same buttons and it walks down the screen and zeros all entires to start over. So it takes all of about 2-3 seconds to clear all entries. You do not need to remove the batteries. Unlike the sporty's version this one has lighted keys! If you were trying to use this in a darker environment no problem... you could be in big trouble trying to do that with sporty's. The screen on sporty's lights up but NOT the keys. Another thing I like better is the keys are bigger on the ASA !! NICE! I was far less likely to make a typing mistake by hitting the wrong key. The sporty's version has very small keys... easy to make a mistake.... and I don't need any help making mistakes I can do that all by myself pretty easy lol. The buttons on the ASA feel very sturdy... easy and predictable when pressed with a distinct 'click' when doing so. Not as obvious with the sporty's. So all in all after trying both I definitely liked the ASA version the best. Plus it looks cool... modern. You can even change the color of the text. About the only thing I could complain about is it came with no user manual. These days not big deal just look on-line right?.... But it would have been a real 10 out 10 if it came with a small cheat sheet that fit right in the cover that would help you know which screen for what answer... like 'Endurance = Fuel' or TR'cs = TRIP .. you figure it out but a little cheat sheet would have been the ACE in the hole. You won't be disappointed with the ASA version. It feels solid and seems very well made. Its operation is just about as novice / user friendly as you could get.

I got this to help with calculations in aviation. I cannot tell you how much this has helped and saved time instead of using a manual E6B. I have been able to calculate IFR climb gradients in significantly less time than with a normal calculator and the manual. I've had this for about six months, and I've loved every minute. I've only had to change the batteries once.

A must for flight students! This will make your written tests much easier!

This calculator literally got me my writing with 10-15 minutes and the manual before hand. This handy little thing will carry you through private pilot utilize only it, and you will not regret buying it as long as you learn it first. but you will probably sell it to a junior pilot before the airlines once you get into a flight bag/app sportys or ect. This calculator loses some of it's appeal but is worth it for early private pilot students.

All good

I originally used an old fashioned manual e6b, however after using this electronic one, I could never go back. It makes life SO much easier when doing written questions for PPL and is super easy to use. Saves so much time and the built in calculator feature helps a ton. Must have for students taking the PAR. Trust me.

My bad, thought it was the sportys calculator us d in their pilot training courses.

I bought this device to pass a test. It’s allowed to take it with you.Computer came well packed, in good condition. It has good built quality.Black color looks exactly like on photo.It has a small size, a little bit bigger than a cellphone. Has all necessary functions to complete test.Computer needs 4 small batteries you may by in any store and ease to change.Not difficult to use it, you may watch some video lessons and review.Bought it year ago still working.
