The earliest landing place of the plane is the grass, usually the circular lawn. Planes can take off and land at any angle along the favorable wind direction, and there will be anemometers and hangars around them (because planes at that time were usually made of wood and canvas, they would not be hit by wind and rain, and they would not be exposed to the sun and rain).
After that, the area of soil field was used to avoid the increase of lawn resistance. But the soil yard is not suitable for humid climate, otherwise it will be muddy. With the increase of aircraft weight, the requirements for take-off and landing have also increased, and concrete runways have begun to appear. This runway is suitable for any weather and any time.
infrastructure
Airports can be divided into "unrestricted areas" and "restricted areas" (controlled areas). Unrestricted areas include parking lots, bus stops, oil storage areas and off-road roads, and restricted areas include all places where aircraft enter, including runways, taxiways, aprons and oil storage areas. Most airports will be strictly controlled in the middle range from non-restricted area to restricted area.
Passengers entering the restricted area must go through the terminal, where they can buy air tickets, undergo security check, check in or pick up their luggage, and board the plane through the boarding gate.
