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.

3. How to divide the airport level?

The classification of airports is determined by two factors, one is the length of the basic flight field and the other is the height of the flight area, which depends on the distance between the farthest two wheels. According to this parameter, it can be guaranteed that the aircraft operating in an airport can be divided into six categories: A to F, including determining the aircraft suitable for parking in each parking space.
