Abstract

In 1983, the ICAO Council was tasked by its special committee on the Future Air Navigation System (FANS) to provide recommendations to the States with the objective to upgrade the communications, navigation and surveillance systems to cope with the growth of worldwide air traffic. The concept of FANS relies on digital communications (datalink) and aims at enhancing air space capacity, efficiency and safety. The datalink system that provides communication between aircraft and ground may be divided into two parts: applications (safety and non-safety services) and infrastructure (networks and subnetworks). In other words, datalink can be interpreted as applications-over-infrastructure. Safety services applications included in the scope of Air Traffic Services (ATS), such as Automatic Dependent Surveillance – Contract (ADS-C) and Controller-Pilot Data Link Communications (CPDLC), employ network infrastructures such as Aircraft Communications Addressing and Reporting (ACARS) and Aeronautical Telecommunications Network (ATN). ACARS and ATN have several limitations (bandwidth, cost of infrastructure and operation) that challenge the implementation of next generation Air Traffic Management (ATM) concepts such as 4D Navigation (or Trajectory-Based Operations, TBO) since it requires high performance but low cost data exchanges between aircraft and ground systems. 2 Envisioning the means to address these limitations, the industry (Boeing, Honeywell, Inmarsat and SITA) are researching the potential use of a high performance Internet Protocol Suite (IPS) network in the eventual place of ACARS and ATN, and also the interoperability and compatibility of IPS with existing aircraft and ground systems. This research includes initial development of a more efficient and backward-compatible connectionless variant of the VHF Digital Link (VDL) Mode 2 subnetwork. In this paper, we will depict the FANS concept, the aforementioned research being conducted by these companies and the possibilities of implementation in Brazil.
