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.
