The invention relates to a method for optimizing the display of data relating to the risks associated with obstacles. The method includes extracting from an obstacle database, a list of obstacles included in the geographic zone defined by the range, the orientation and the position of the aircraft. Obstacle related information and warning lists are received. The obstacle list is regrouped by applying to the obstacles criteria relating to the proximity of the obstacles relative to the aircraft; to the proximity of the obstacles to one another; and to their warning level. The symbology adapted to the obstacle display is generated. In particular, the invention applies to optimizing the display of warnings relating to the risks of collision with point-like or linear obstacles.
