  1. RNAV 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

  2. Oceanic Airspace • Implemented 50NM lateral and longitudinal separation minima (based on RNP10) 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 airports Current RNAV Procedures in Japan

  3. 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 Background

  4. 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. Systems Procedures • Restructuring of ATS routes and airspace • Flexible use of airspace • RNAV • Reduction of separation minima • New ATC workstations with controller support tools • Data link (ADS/CPDLC) • GNSS Capacity and Efficiency 52

  5. 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 • 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 Initiatives

  6. 1. Reviewed current operations (en route and terminal) 2. Studied current and forecasted aircraft equipage 3. Studied airspace and infrastructure • 4. Reviewed procedures currently available and identified procedures to be developed • Certification, Operational Approvals, Design Criteria, ATC Procedures, and Flight Inspection International Harmonization JCAB Study

  7. RNAV Routes in Japan Radar Coverage (above 15,000 ft MSL) Radar Coverage (above 30,000 ft MSL)

  8. GNSS (GPS, SBAS) • DME/DME (two DME) • VOR/DME (single VOR/DME) • Self-contained navigation system (IRU, INS) • Combination of above Non-RNAV capability B-747 classic GPS (without IRU) DME/DME+IRU GPS+DME/DME+IRU Surveyed commercial passenger/cargo aircraft registered in Japan RNAV Systems & Equipage

  9. Surveyed commercial passenger/cargo aircraft registered in Japan * Capable as determined by equipment only. Crew training is not considered Know our aircraft

  10. 12,000 MSL 29,000 MSL DME/DME, VOR/DME RNAV Total System Error 5NM 12,000 MSL 29,000 MSL DME/DME RNAV Total System Error 2NM Know our airspace - 1

  11. 12,000 MSL DME/DME RNAV Total System Error 1NM 8,000 MSL 2,000 MSL Know our airspace - 2

  12. Major issues considered • International Harmonization • Increase capacity; Tokyo 4th Runway and Kansai 2nd Runway Implementation Phase • - 2007 : Introduction of internationally harmonized procedures • 2008 - 2012 : Increase capacity and efficient operations • 2013 - 2017, beyond : Future direction RNAV Roadmap

  13. En Route • Implement RNAV5 routes as an interim step for radar airspace • Operationally segregate between RNAV flights and VOR flights • Implement RNP2 routes, and expand RNP2 routes to non-radar airspace • Expect to mandate RNP2 above FL290 Reduce ATC complexity, Increase capacity, Improve efficiency RNAV Roadmap - 1

  14. Terminal • Implement RNAV1 SID/STARs for radar airports • Airspace restructure at major airports • Implement RNP1 SID/STARs for non-radar airports • Expect to mandate RNP1 in mid-high density airports • By 2009 RNAV will be available at major city pairs in Japan from departure to arrival. • By 2012 RNAV will be available at most of the airports in Japan. RNAV Roadmap - 2

  15. Approaches • Evolutionary implementation of RNAV (GNSS) approaches with Baro-VNAV • Implement RNP AR approaches at airports, where beneficial Increase runway access, Increase safety, Reduce noise RNP AR approaches will increase runway access RNAV Roadmap - 3

  16. Japan Roadmap for RNP
