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.

Method and device for assisting navigation

A method for assisting the piloting of an aircraft from a voluminous set of memory-stored documents which uses a processor associated with a terminal comprising a screen and control and data entry keys and with memories containing useful information for operating a flight, the processor being connected to other items of equipment of the aerodyne. The method comprises storing of information in a data base and supplying first exploitation functions of this information, real-time acquisition by the processor of an event relative to the current situation of the aerodyne and analyzing the new situation generated by the occurrence of this event, preselecting the information in the data base best adapted to the new situation, and classifying same by order of relevance, supplying second exploitation functions of the preselected information, selection and exploitation, by the operator, of one of the exploitation functions. The method applies in particular to the civil and commercial aviation.

A method which uses a terminal comprising a processor, a screen and a keyboard, comprises step by step breakdown of all the information ('checklist') to be structured into subsets and identification of their structure, grouping together by similar structures of the subsets into objects ('blocClist', 'tiCL', 'tiblocCL', 'remark', 'item', 'Sdeb', 'verif', 'Sfin'), input into the terminal of each object, in the form of a graphical symbol representing a node, and of the characteristics thereof, input into the terminal of link type symbols connecting two objects indicating a hierarchical include relation between two objects, translation by the terminal of the graph thus derived into a structure model expressed in a computer language and monitoring of the consistency thereof. The method applies notably to the management, by an on-board computer in an aircraft, of the lists of tasks to be performed during the phases of piloting.
