No, it downloads detailed terrain data while flying. The game uses up to 150 GB on your SSD/HDD but the world data is 2 peta bytes in total. Without internet connection you still get good results with procedural generation filling in the gaps, yet when connected it will stream higher quality terrain textures and accurate building data for where you are.
Realtime weather is no more data than checking the weather report, FSX did that already in 2006. Other plane locations is very little as well.
