Flying in China
Hello, I have been flying in China for going on 2 years and here is my view.
1. The controllers are required to speak English to foreign flight planned crews. (they do wonder off and start speaking Chinese, just reply in English).
2. Cargo, I think it may be true that cargo is loaded on the plane without paperwork. Just keep that in mind when you fly but I would think it is small amounts, who knows.
3. Metric altitudes you convert to feet for your airplane.
4. QNH but there are a few QFE airports
Many other factors that are different from the west.
Good Luck, On Final
