The ASA CX-3 is the electronic flight computer used for DGCA Air Navigation and flight planning — wind correction, time–speed–distance, fuel, density altitude, weight and balance, and unit conversions. Practice here with the official Prepware demo; carry a physical CX-3 in the exam hall (online devices are not allowed).
What you can calculate
- Time, speed, distance and wind triangle (WCA, heading, groundspeed)
- Fuel burn, endurance, and range
- Density altitude, true airspeed, Mach, ISA deviation
- Climb, descent, glide, cloud base, weight and balance
Pair with the Air Navigation guide or BlueFlash voice tutor to learn the concepts behind the numbers.
