Can I watch the cached video on the plane?

Of course. According to the information of the weather network, as long as the flight mode is turned on, you can always play with your mobile phone, and the cached video will not affect the flight of the plane. Domestic airlines have gradually opened up the use of portable electronic devices on airplanes. Airlines that have started using mobile phones on board are: Eastern Airlines (including Shanghai Airlines), Hainan Airlines, Capital Airlines, China Southern Airlines, Xiamen Airlines, Chongqing Airlines, Sichuan Airlines, Fuzhou Airlines, Hebei Airlines, China Bank, Hongtu Airlines and Chengdu Airlines.
