The invention discloses a method for precisely the pre-estimating estimated arrival time of flight, and the method is integrated with a civil aviation data query system. The method comprises historical data storage, and comprises the steps: 1, building a virtual cube CUBE, selecting data with the same data dimension according to the historical data storage, and enabling a historical sample to enter into a model, wherein the data longitude difference is less than 0.25565, the latitude difference is less than 0.11225, and the height difference is less than 209.3; 2, carrying out the layering arrangement of the virtual cube CUBE, building all layers according to a landing runway dimension, carrying out the data processing of all internal layers of the virtual cube CUBE, calculating the mean value of landing time differences t between other similar samples in history, and enabling the landing time differences t to serve as a prediction value of the landing time t of the sample. According to the invention, the method comprises the steps: inputting a to-be-obtained estimated time flight; obtaining the current data of the flight; entering into the virtual cube CUBE for processing; and outputting a prediction time. The method aims at predicting the arrival time of the flight 30 minutes ahead, and guarantees that the time difference between the arrival time of the flight and the actual landing time is within the range of +/-5 minutes.
