Abstract:
1. Device for monitoring location of an aircraft in relation to cooperative craft, the said aircraft being provided with a geographical location system is cooperative with a data communication network, comprising: an onboard means for broadcasting data in an automatic manner to non-designated recipients cooperative with the communication network, an onboard means for receiving the data transmitted by transmitters cooperative with the communication network, the data comprising at least indications of location and displacement of cooperative aircraft, a cost surface database storing a first conflict cost surface encompassing the deployment surface, related to cooperative aircraft and defined by the ratings assigned to its points, representative of their memberships in a congestion zone covering the vicinity of the current positions of each cooperative aircraft, of the uncertainties in positioning of the aircraft and of the safety margins to be complied with in relation to the aircraft and a second conflict cost surface encompassing the deployment surface, related to the aircraft on board which the monitoring device is carried and defined by the ratings assigned to its points, representative of their memberships in a congestion zone covering the vicinity of the current position of the aircraft, of the uncertainties in positioning of the aircraft and of the safety margins to be complied with in relation to the aircraft, and calculation means computing a score for evaluating the significance of a risk of violation of a traffic flow constraint incurred by the aircraft on the basis of an inter-correlation function of the two dangerousness cost surfaces referred to one and the same benchmark.
