The Difference between Chang Fei Quasi-professional Edition and Free Edition

Hello, would you like to ask what is the difference between the free version and the paid version of Fei Chang Zhun pro? The difference between the paid version and the free version of Changfei Zhun pro lies in the different functions. Because the paid version of Changfei Zhun pro has the functions of checking the age of the aircraft, airport traffic conditions and airport weather, but the free version does not have these functions, the difference between the paid version of Changfei Zhun pro and the free version is the functional difference.
