    • The best flight calculator on the market (June 2025)
The best flight calculator on the market (June 2025) It does everything the whizz wheel does. plus so much more. The back light is very useful too. Easy to read, fast calculations (mostly instantanious), yes its complicated - the instructions are clear and once you have read them and practiced a bit - it soon becomes very easy. Hey if you're a Pilot, you are not stupid, so you can easily use this amazing calculator - the only thing it doesn't do is make the tea / coffee - which you can do whilst reading the instructions on your iPad! Happy Landings. ... show more

    • An Absolute Must for FAA Written Exams
I'm very pleased with this flight computer. It has the essential functions required for FAA written exams, including wind correction, weight & balance, temperature/airspeed/altitude, unit conversions ... as well as "basic" calculator. Calculations are a breeze once you've worked only a couple examples to learn the ropes in navigating between the various menus. I found using this computer on the FAA exams to reduce stress significantly -- calculations are faster and more reliable (no chance of reading the wrong window/scale!) than with an E6B. I definitely recommend for those working to add to ratings to their pilot certificate! ... show more

    • Trip Plan function is stellar ....
I like mine, the back-light options are nice for either night or day. It's a handy size, has a quality feel to the case and keypad and the protective cover is great for throwing it in my backpack. I'm presently a Private Student Pilot and it’s taken time for my old-school instructor (40 years flying) to warm up to the idea but making changes for crosswinds or fuel burn can't be beat when compared to using the mechanical E6Bs. In addition I don't believe they can manually obtain the same level of accuracy regardless of what the ol' timers may say. The weight and balance function, while admittedly I haven't used it much in instruction, is a breeze once you have the values. Given that taking the Knowledge Exam comes at a reasonably steep price this will be a time saver so I can spend more time on other questions. Be aware, this alone will not get you through your exam, or even your instruction. For example, while the Trip Plan function is stellar you still need to provide the device values like winds aloft speed and fuel burn to get accurate results. Determining fuel for taxi and takeoff, climb to altitude and cruise burn per hour rates are not inclusive in this E6B capability and come from elsewhere as per your ground school preparation. It’s taken me some time to recognize its value and function but now it’s another tool in my kit and I wouldn't give it up going forward. It will get plenty of use even after my license is obtained. I’ve never held the competing products in my hand (Sporty’s etc.) but I feel the few extra bucks were well spent on the ASA. ... show more

    • 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. ... show more

    • Helped me save time and pass my test!!
Would highly recommend this to any pilot that is in the process of training. I recently had to take my private pilot test and this was a live saver. I didn’t like the “guesswork” of the manual e6b. I could struggle my way through it, but it wasn’t very precise. This is a totally different story. It is super easy to use. Gives precise calculations. Is FAA approved for use on knowledge exams. And saves so much time and headache with a bunch of different questions. Well worth the investment if you are still in flight training. Fits well in a flight bag to help with all of your cross country flight planning needs, has a backlight so it can be used in the light or dark and the display is super easy to read. ... show more
