CX-3 Flight Computer

I am teaching PPL ground school. I recommend to all my students the physical ASA CX-3 for the FAA knowledge tests. This app allows me to demonstrate the functions on my iPad, if needed projected to a bigger screen. I find myself even using it at home, when again I cannot remember where I put my physical CX-3. Sure, ASA has the Web demo app, however, it is beneficial to have an app independent of WiFi or cellular access. Well worth a small fee.

I use this tool everyday, what’s great is it also works offline unlike the website. If you in aviation school I would definitely recommend buying this app. I only deducted a star because some users say the calculations to be inaccurate but I believe they fixed those issues but I have also never experienced those problems, the app works well for me and I think it will for you too.

I use this for my students while their calculator is on order.

I think they’ve fixed the calculation issues with W/B because I haven’t experienced them.
