Thank you very much for your question. According to the domestic aviation safety law, electronic equipment, including notebook computers, tablet computers, radio equipment, etc., must be shut down or enter flight mode during take-off and landing; It can be used when flying in the air, but it must follow the instructions of the crew. As a special kind of flight equipment, UAV needs to apply for a legal flight site and a license for aviation flight equipment before flying. Therefore, two notebooks and a drone can be brought on the plane, but they need to be operated according to the corresponding regulations.
