The development of commercial aviation is mainly manifested in the rapid growth of passenger traffic and freight volume, and the scheduled routes are densely distributed in all continents of the world. Due to a series of advantages, such as rapidity, safety, comfort and being free from terrain restrictions, commercial aviation occupies a unique position in the transportation structure, which promotes the development of domestic and international trade, tourism and various communication activities, making it possible for remote areas to develop in a short time.

General aviation services for industry and agriculture mainly include aerial photogrammetry, aerial geophysical exploration, sowing, fertilizing, spraying pesticides and aviation forest protection. It has the outstanding advantages of high working quality and saving time and labor. Helicopters also play a unique role in offshore oil exploration and aerial lifting operations. In some countries with developed aviation, the main components of general aviation are official flights and commuter flights of government agencies and enterprises. This is because the airlines' regular routes can't meet this scattered, regular and irregular demand. In addition, general aviation also includes personal entertainment flights, sports performances and competition flights.
