Claim:
A method for optimizing an obstacle-related data display receiving information necessary to define a zone comprising the obstacles to be displayed, comprising the following steps: extracting from an obstacle database, a list of obstacles included in a geographic zone defined by a range, the orientation and a position of an aircraft; receiving an information list and an obstacle-related warning list generated by an obstacle collision prediction and warning device; filtering and regrouping via an obstacle filtering device the obstacles of the obstacle list by applying to the obstacles criteria relating: to a proximity of the obstacles relative to the aircraft; to a proximity of the obstacles to one another; to a warning level; generating a symbology adapted to the obstacle display, wherein the filtering and regrouping step comprises a filtering step, said filtering step comprising the following steps: a step of initializing a variable n at the value of the smallest possible position of an obstacle in the list of obstacles filtered according to their elevation; a step of extracting an obstacle O(n) whose position in the list of obstacles filtered according to their elevation is equal to n; a step of initializing a variable p, fixed at one unit; a step of extracting an obstacle O(n+p) whose position in the list of obstacles filtered according to their elevation is equal to n+p, a step of comparing a distance d(O(n),O(n+p)) between the obstacle O(n) and the obstacle O(n+p) with the minimum distance D: when the distance d(O(n),O(n+p)) is greater than or equal to the minimum distance D, there is a move to a step of incrementing the index p by a unit; when the distance d(O(n),O(n+p)) is less than the minimum distance D, there is a move to a step of searching.
