Air safety is requiring the highest level of equipment (ILS, VOR, multilateration, VHF …) in order to ensure the reliability of the air traffic management, the communication, navigation and surveillance of the aircraft from its take-off until its landing. Research continues to improve in particular the and the safe functioning of installations, the operational efficiency of air traffic control throughout all phases of flight and the tools used by the Civil Aviation and the airports in order to make the most of air-ground data links trough radar and radar image process. The growth of air traffic is causing more and more congestion and delays. Given its complexity and the number of stakeholders, solutions to this problem may only be by introducing new concepts into air traffic management such as Gate-to-Gate project , a seamless gate-to-gate approach developed in order to bring solutions to the operational problems of the ATS providers.
