RNAV RNA and RNP Strategy in Japan ICAO Worldwide Symposium on Performance of the Air Navigation System Montreal, 26 - 30 March 2007 Yoshiki Imawaka Director for International Policy Coordination ATS Systems Planning Division Civil Aviation Bureau, Japan 25/09/2020 Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 1

Current RNAV Procedures in Japan Oceanic Airspace • Implemented 50 NM lateral and longitudinal separation minima (based on RNP 10) over NOPAC and CENPAC since 1998 and 2006, respectively En Route • • Established three RNAV routes in 1992 Implemented 60 RNAV routes as of March 2007 Terminal Area • • Established FMS arrival route in Tokyo (Haneda) in 1999 Expanded to five other airports since 2004 Approaches • Established RNAV (GNSS) approaches with Baro-VNAV at selected 25/09/2020 Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 2

Background Growing traffic demands Q JCAB has predicted that air traffic in Japan will increase by 34 percent from 2005 to 2017 Q New runways at airports in Asia Fuel savings and reduce noise Q Reduce fuel, reduce emissions and reduce noise High performance aircraft Q Increased number of aircraft equipped with multifunctional FMS and GPS 25/09/2020 Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 3

Capacity and Efficiency Q In order to accommodate growing traffic and increase efficiency, new capabilities should be introduced. Q 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. Procedures Q Restructuring of ATS routes and airspace Q Flexible use of airspace Q RNAV Q Reduction of separation minima 25/09/2020 Systems Q New ATC workstations with controller support tools Q Data link (ADS/CPDLC) Q GNSS Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 4

JCAB Initiatives JCAB established a Steering Committee and Work Group in 2004 Q Composed of JCAB, operators, and aviation industry representatives Q The purpose was to review the current RNAV procedures, and develop an RNAV implementation plan for Japan Q Developed “RNAV Roadmap for Japan” in April 2005. Q Decided on an evolutionary implementation of RNAV procedures in Japan, and to continue working collaboratively with the operators on the implementation. Q Established RNAV Implementation Team in October 2005 for implementing RNAV according to the RNAV Roadmap. 25/09/2020 Worldwide Symposium on Performance of the Air Navigation System, Montreal, 29 March 2007 5

JCAB Study 1. Reviewed current operations (en route and terminal) 2. Studied current and forecasted aircraft equipage 3. Studied airspace and infrastructure 4.
