ABSTRACT:
The present invention relates to a method of assisting the piloting of an aircraft at low altitude. According to the invention, a hypothetical curve associated with an optimal theoretical trajectory for clearing an obstacle is calculated and, in the field in front of the aircraft: all the obstacles situated in a search area are determined; the tops of the obstacles determined are compared with the hypothetical curve; an obstacle is defined as a dangerous obstacle if the top of the obstacle is situated highest with respect to the hypothetical curve; and the coordinates of the top of the dangerous obstacle are communicated.
