Summary: | The invention provides a calculation method of a flight track symbol used as an aircraft landing control reference. The calculation method comprises the following steps: S1 calculating a lateral instruction of the flight track symbol based on course and track parameters; S2 calculating the height of a main wheel based on the air pressure height and the radio height; S3 when the height of the main wheel is lower than a first threshold value, judging whether the aircraft arrives right above the road surface or not, and if not, calculating a flight track symbol longitudinal instruction based on the vertical speed from the sensor group; if so, carrying out the next step; S4 judging whether the aircraft is located on the road surface or not, if not, calculating the vertical speed of the aircraft relative to the road surface, and calculating a flight track symbol longitudinal instruction based on the vertical speed relative to the road surface; if so, carrying out the next step; and S5 setting the longitudinal inst |
