Patent ID: 7492307

Claim:
Equipment, for aircraft, for anticipating collision risks comprising: an SSR transponder supporting a data transmission channel, an SSR interrogator adapted to an SSR transponder, a computing unit provided with: means for managing the SSR transponder and the SSR interrogator, estimation means for estimating the relative distances and bearings of aircrafts responding to the requests of the SSR interrogator, SSR interrogator request specifying means specifying requests for communication of estimated relative distance and/or of estimated relative bearing, SSR transponder response specifying means for making it possible, on the request of an SSR interrogator of another aircraft flying in the vicinity, to include in the response given by the SSR transponder of the aircraft, a value of relative distance and/or of relative bearing provided by the estimation means, said specific requests and responses being carried by the data transmission channel, Concordance checking means for checking the concordance between the relative distance value and/or the relative bearing value of an aircraft provided by the estimation means and the value of relative distance and/or of relative bearing communicated by that aircraft by means of its SSR transponder, and discordance alarm means that, in the case of discordance detected by the concordance checking means, provokes the generation of a discordance alarm message by the SSR transponder response specifying means, relayed by the SSR interrogator and containing the registration number of the aircraft which is at its source.
