Simple yet powerful app from a pilot to pilots.
This application can calculate actual wind while you are flying.
If your aircraft doesn't have modern glass cockpit instruments than this application is for you. You can determine the actual wind, drift angle, true air speed and ground speed, while cruising.
Enter Calibrated Air Speed, Altitude and OAT data and application will calculate TAS for you, alternatively enable "Manual TAS Input" mode and just enter TAS data.
Also you can use this application in "Simulation Mode" as a E6B computer while you are not flying by enabling "Simulation Mode" and entering Track and Ground Speed data.
Hope this application helps you. Have a good flight and landing.
