Abstract
A method and a device for avoiding an object by detecting its approach to an aircraft. After detecting an object in the vicinity of an aircraft and detecting its approach, a first track for the object and a second track for the aircraft are estimated from successive first states for the object and successive second states for the aircraft. Thereafter, a minimum distance (dm) between the first track and the second track is estimated and a warning is triggered as soon as the minimum distance is less than a first threshold so as to warn a crew of the aircraft of a risk of collision. Finally, if the minimum distance is less than a second threshold, an avoidance maneuver is performed automatically by the aircraft in order to move away from the first track, and thereby avoid any risk of collision with the object.
