The development of aviation has greatly changed the structure of transportation. Air transportation provides people with a fast, convenient, safe, and comfortable means of travel. International flights have replaced ocean going passenger ships and become the main tool for people's intercontinental communication, closely connecting and interacting with countries around the world. The air transportation of domestic routes can already compete with railway transportation in developed countries and regions, and has accelerated the development and development of remote areas in developing countries. Communication satellites and large passenger planes are considered two important pillars of modern society. The application of aviation in industry and agriculture is also evident, such as light aircraft, which are widely used in aerial photography, geodetic surveying, geological exploration, and resource investigation. They can also be used for sowing and fertilizing, weeding and pest control, forest fire prevention, and environmental monitoring and protection.
