Aviation Electronic E6B

Based on the ASA CX-3® Flight Computer for pilots, this CX-3 app makes flight planning simple by taking confusion out of the equation. Fast, versatile and easy to use, the CX-3® delivers accurate results quickly and efficiently. Whether used for flight planning, ground school, or FAA Knowledge Exam preparation, the menu organization reflects the order in which a flight is normally planned and executed, resulting in a natural flow from one function to the next with a minimum of keystrokes. Multiple aviation functions can be performed on the CX-3® flight computer including those related to time, speed, distance, heading, wind, fuel, altitude, cloud base, standard atmosphere, glide, climb & descent, weight & balance, as well as a holding pattern function to help determine entry method and holding details. The CX-3® has 12 unit-conversions: Distance, Speed, Duration, Temperature, Pressure, Volume, Rate, Weight, Rate of Climb/Descent, Angle of Climb/Descent, Torque, and Angle. These 12 conversion categories contain 38 different conversion factors for over 100 functions. A calculator, clock, timer, and stopwatch are also built in along with multiple settings for lighting, backlighting, themes, time zones and more.

Very Useful Tool

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.

Perfect for my class

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.

No issues

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