Review: ASA vs Sporty's ASA Wins! - 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. Review: Great tool-Don’t leave home without it! - Excellent tool. It is intuitive and makes life so much easier. Weight & Balance calculations a little hard at first, but once you get the hang of it it’s just fine. I did a couple of fictitious calculations to get the hang of it. The only issue I found is it is hard to get the back off to get to the battery compartment. Also, for what it costs, you would think ASA could print an instruction manual instead of referring you to a web site and YouTube. Other than that, I love it. I think you will too. ## Features - FAA-Approved for Written Exams: Take the CX-3 directly into FAA knowledge tests—no memorization required.

However, wind is given as true north so the first thing you need to do is change it to magnetic by subtracting the magnetic variation. I gave up on the CX-3 and went back to my whiz wheel. **Q: Can this asa cx-3 flight computer be used on the faa private pilot knowledge exam?** A: Yes, you can use it on the knowledge exam. **Q: I’m having a problem. Daytime mode looks a bit cloudy . Dark splotches and bright points . Is that normal ?** A: Yes. But make sure you have done the software updates. **Q: How do you clear the memory as needed for the FAA exams?** A: It does not have a memory like a scientific calculator. There's nothing to clear. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ASA vs Sporty's ASA Wins! *by G***X on March 12, 2025* I bought this and the sporty's flight computer to compare.
