Current RNAV Procedures in Japan

• Implemented 50NM lateral and longitudinal separation minima (based on RNP10) over NOPAC and CENPAC since 1998 and 2006, respectively

• Established three RNAV routes in 1992• Implemented 60 RNAV routes as of March 2007

Oceanic Airspace

En Route

• Established FMS arrival route in Tokyo (Haneda) in 1999• Expanded to five other airports since 2004

• Established RNAV (GNSS) approaches with Baro-VNAV at selected airports

Approaches


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


Capacity and Efficiency

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


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


JCAB Study

4. Reviewed procedures currently available and identified procedures to be developed Certification, Operational Approvals, Design Criteria,

ATC Procedures, and Flight Inspection

2. Studied current and forecasted aircraft equipage

3. Studied airspace and infrastructure

1. Reviewed current operations (en route and terminal)

RNAV Roadmap

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 - 1

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 - 2

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

Terminal

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.


Evolutionary implementation of RNAV (GNSS) approaches with Baro-VNAV Implement RNP AR approaches at airports, where beneficial

Approaches

RNP AR approaches will increase runway access

Increase runway access, Increase safety, Reduce noise
