3. Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 3 Background Growing traffic demands  JCAB has predicted that air traffic in Japan will increase by 34 percent from 2005 to 2017  New runways at airports in Asia Fuel savings and reduce noise  Reduce fuel, reduce emissions and reduce noise High performance aircraft  Increased number of aircraft equipped with multifunctional FMS and GPS

4. Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 4 Capacity and Efficiency 52  Restructuring of ATS routes and airspace  Flexible use of airspace  RNAV  Reduction of separation minima Procedures  In order to accommodate growing traffic and increase efficiency, new capabilities should be introduced.  New capabilities will employ a combination of procedures and systems, such as a restructuring of ATS routes/airspace, and ATC support tools, which would increase controller capability and reduce workload.  New ATC workstations with controller support tools  Data link (ADS/CPDLC)  GNSS Systems

5. Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 5 JCAB Initiatives  Developed “RNAV Roadmap for Japan” in April 2005.  Decided on an evolutionary implementation of RNAV procedures in Japan, and to continue working collaboratively with the operators on the implementation.  Established RNAV Implementation Team in October 2005 for implementing RNAV according to the RNAV Roadmap. JCAB established a Steering Committee and Work Group in 2004  Composed of JCAB, operators, and aviation industry representatives  The purpose was to review the current RNAV procedures, and develop an RNAV implementation plan for Japan
