Air transport safety, efficiency and growth driven by market demand Success stories There are many success stories that demonstrate the major advantages and benefits of the progressive implementation of ATM_cns. While providing only a partial picture, the following examples illustrate that there are very positive experiences in all regions – based on current technology – as well as promising longer-term prospects. Existing ATM solutions Substantial benefits are already being achieved through the implementation of modern ATM solutions to accommodate appropriately equipped aircraft. These include reducing the vertical and horizontal distances between aircraft, thereby increasing capacity and facilitating optimum routing profiles: reduced vertical separation minima (RVSM) – the reduction of vertical separation between aircraft, normally from 2,000 to 1,000 feet. required navigation performance (RNP) – a global ICAO standard that once implemented enables greater levels of airspace capacity and efficiency. area navigation (RNAV) – permits aircraft operation on any desired flight path within the coverage of navigation aids, or a self-contained navigation system. 10 Examples: Caribbean/Latin America: introduction of RNAV is generating an annual reduction of around 40,000 tonnes of CO 2 emissions. Europe: RVSM was successfully implemented across 41 European and North African States in January 2002. During the first summer of operations, ATM capacity in European airspace was increased by approximately 15%. Europe Middle-East Asia Route Structure South of Himalayas (EMARSSH) project: a new long-range network of routes connecting Australia with Asia (November 2001) and Asia to Europe and the Middle East (November 2002) that has resulted in flight savings of up to 30 minutes.

Taking advantage of existing equipage A number of civil aircraft are already equipped with the technology required to capture satellite signals and to provide controllers with reliable information regarding their position. Boeing and Airbus have introduced communication, navigation and surveillance systems, known respectively as Future Air Navigation System 1 (FANS 1) and FANS A. Today, over 1,000 long-haul aircraft are equipped with FANS 1/A systems, and this is providing significant benefits with reduced separation and user-preferred routes. Air transport safety, efficiency and growth driven by market demand "The development of the future air traffic system will require an unprecedented global approach, going beyond the international collaboration that has been involved in building a large transport airplane or an international space station. It will require working together as a team, integrating ideas, products and technology from around the world on an unprecedented scale". John Hayhurst, President, Air Traffic Management and Member of the Boeing Executive Council 11 Examples: South Pacific: the first FANSequipped aircraft went into service in 1995 between Australia and the US taking full advantage of improved communications, optimum routings, and rapid route-clearance changes. Cross polar-routes: satellitebased navigation has enabled flights over previously untravelled territory using Russian, Canadian and US airspace close to the North Pole. The first official polar route flight between North America and Asia by a commercial airline was conducted in July 1998. Currently, more than 200 flights per month use near polar routes between Europe and Asia and Asia and North America thereby benefiting airlines and passengers through significant time and fuel savings and associated emissions reductions. Southern Africa: satellite-based approach and departure procedures were implemented in 2002 at 37 airports in the 14 Southern Africa Development Community (SADC) States as well as in Kenya and Cape Verde. The project is an excellent example of cooperation between States and IATA to improve navigational procedures, enhance air safety and significantly improve the regularity, efficiency and cost-effectiveness of air transport in Southern Africa. The need for new HF radios on Atlantic routes has been averted through the gradual introduction, over the past few years, of automatic dependent surveillance (ADS) waypoint reporting – which allows better flight plan conformance monitoring and a reduction in gross navigation errors. Gate to Gate and free routing Looking to the future, the air transport industry considers that an essential element of the Global ATM Implementation Roadmap will be to increase aircraft autonomy by transferring certain procedures and responsibilities from the ground to the aircraft. This will be achieved progressively through: advanced concepts such as flexible tracks, random routing, dynamic re-routing and free routing where appropriate; greater use of data link and satellite technologies that allow for improved communications between pilots and controllers; aircraft operators fully utilising sophisticated flight management systems to take advantage of reduced fuel load, favourable winds and the ability to avoid bad weather; and a seamless and coherent management approach to all phases of flight starting from the initial airline planning months in advance, continuing with gate-togate flight operations and finishing with the performance registration and user charges calculation. This calls for close cooperation between aircraft operators, airports and air navigation service providers in a collaborative decision-making (CDM) process.
