The method is implemented using an RTS server (Real Time Server) configured to communicate with navigational devices on board aircrafts and provided with an application configured to communicate data concerning the position of the aircrafts to the RTS server. ## Claims ### Claim 1 An aircraft traffic control method comprising: receiving data concerning the position of aircrafts; creating a real-time map of aircraft traffic based on the position data; checking the possibility of a collision between aircrafts on the basis of the map, and in the event that such check is positive, sending an anti-collision alert to the aircrafts, said method being implemented by means of an RTS server (Real Time Server) configured to communicate with navigational devices on board the aircrafts and provided with an application configured to communicate data concerning the position of the aircrafts to the RTS server and to determine the ideal route and ideal level of flight in compliance with Visual Flight Rules (VFR) and the areas of overflight defined by aeronautical mapping, said application being interfaceable with the aircraft flight control system. ### Claim 2 (depends on 1) The method of claim 1, wherein the RTS server may execute processing algorithms that determine the parameters required for aircraft control in order to avoid unlawful violations of controlled airspaces or of airspaces subject to particular flight regulations. ### Claim 3 (depends on 1) The method of claim 1, wherein the RTS server may provide information about aircrafts flying inside an airspace to the application operating on the navigational devices on board the aircrafts flying in said airspace to indicate routes followed by aircraft and alarm states in the case of incompatible routes or foreseen collision in order to alert all affected aircrafts. ### Claim 4 (depends on 1) The method of claim 1, wherein the application operating on a navigation device of an aircraft can be interfaced with a GPS system to communicate to the RTS server the GPS positioning data of the aircraft and the flight plan. ### Claim 5 (depends on 1) The method of claim 1, wherein the application operating on a navigation device of an aircraft may define an inviolable security volume around the aircraft itself. ### Claim 6 (depends on 1) The method of claim 1, wherein the RTS server may transmit data to flight control towers of the various airports and may allow connection to the RTS server by the airport flight control system. ### Claim 7 (depends on 1) The method of claim 1, wherein the application operating on a navigation device of an aircraft can be interfaced with the flight control system of the aircraft. ### Claim 8 (depends on 7) The method of claim 7, wherein the application operating on a navigational device of a rotating wing aircraft can control the autorotation of the rotating wing aircraft by providing ground approximation data and an alert when the distance is optimal to make the final landing flare. ### Claim 9 An aircraft traffic control system, wherein the system comprises a RTS server configured for remote communication with aircraft navigation devices present on board the aircrafts and provided with an application, wherein said application is configured to communicate data regarding the position of the aircrafts to the RTS server, and to determine the ideal route and ideal level of flight in compliance with Visual flight rules (VFR) and the areas of overflight defined by aeronautical mapping, said application being interfaceable with the aircraft flight control system and wherein the RTS server suitable for receiving aircraft position data for creating a real-time map of aircraft traffic based on position data and for checking based on that map the possibility of collision between the aircrafts, and in the event that such check is positive, for sending an anti-collision alert to the aircrafts.
