Abstract
The method for assisting navigation of the invention uses a documentary management system including a processor associated with memories containing at least the stored image of a map of the region traversed by the vehicle and information relating to a multiplicity of objects localized in said region, this information being divided into sets of objects having their own exploitation means. This method includes the acquisition of the position of the vehicle, the introduction of the trajectory to be crossed from this position, the displaying of a geographical zone including said position and one significant portion of the trajectory to be travelled through, the displaying of a symbol representative of the vehicle, the selection by the operator of a set of objects, the selection by the system of the information of this set relating to the localized objects in said zone, the display by overprinting of the symbols thus selected, the selection by the operator of one of said sets and activation of the exploitation means associated with this set Application is in particular to civil and commercial aviation.
