Data-driven aircraft safe landing interval indication method

The invention discloses a data-driven aircraft safe landing interval indication method, which comprises the following steps of: 1, accumulating historical data: constructing a safe operation historical database of an aircraft approaching process, collecting landing data, and screening and storing the landing data in a standardized manner; step 2, calculating a safety interval range: constructing a standard landing line, an early warning line and a prohibition line of a vertical section and a horizontal section in an aircraft landing process based on historical data in the safety operation historical database, and obtaining the safety interval range in the aircraft landing process; and step 3, carrying out auxiliary decision making: indicating the aircraft landing process based on the safety interval range, and assisting a commander to make a decision. The method is driven by data, has the characteristics of strong pertinence and good adaptability, can fit the actual flight conditions of different airports, ca
