The invention discloses a method and device for predicting the estimated arrival time of a flight path and an automatic prediction system. The method comprises the steps: acquiring real-time position information of an aircraft entering a prediction area; triggering an electronic fence in a pre-established prediction model according to the real-time position information of the aircraft, and calculating first prediction time Td consumed from the time when the electronic fence where the aircraft is located currently to the time when the aircraft receives the runway alignment signal; according to the runway alignment information of the aircraft, acquiring second prediction time Ts required to be consumed from receiving the runway alignment signal to actually landing; and according to the first prediction time Td and the second prediction time Ts, calculating the arrival time of the aircraft based on the sum of the current time. Therefore, by implementing the prediction scheme disclosed by the invention, the prediction deviation caused by sudden factors can be effectively reduced, the airport flight arrival time prediction precision is improved, airport guarantee resources are prevented from being wasted, and potential safety hazards caused by inaccurate arrival time prediction are eliminated.
