摘要

The method involves receiving and storing identifier and dated position fix by aircrafts (202-205). The identifier and dated position fix are downloaded toward a database by the aircraft after landing. A known position of the aircrafts is determined from the dated position fix stored in the database in case of disappearance of another aircraft (201). A path of the latter aircraft is determined from the dated position fix stored in the database.
