**THE TWENTY-EIGHTH MEETING OF THE**

**INFORMAL PACIFIC ATC CO-ORDINATING GROUP**

**(IPACG/28)**

(Las Vegas, USA, 12-16 May, 2008)

Agenda Item 5: Air Traffic Management (ATM) Issues

**Restructuring plan of the Kanto airspace surrounding the Tokyo and
Narita international airport**

(Presented by the Civil Aviation Bureau, Japan)

1.  Background

    1.  It is expected that future demands on aviation in Japan (both
        international and domestic) will continue to increase, despite
        temporary stagnation due to events such as the Severe Acute
        Respiratory Syndrome epidemic. In particular, the demand on
        aviation operations between Japan and Asia is expected to vastly
        increase due to the economic expansion occurring in China and
        Southeast Asian country.

    2.  To cope this situation in Japan, The Civil Aviation Bureau of
        Japan (JCAB) is planning to open fourth runway of the Tokyo
        international (Haneda) airport, and to extend length of the
        runway 34R/16L of the Narita international airport. The fourth
        runway of the Haneda airport will open at autumn in 2010, and
        the capacity of the Haneda airport will be 407 thousand
        movements par year (1.4 times to current capacity). The runway
        34R/16L of the Narita international airport will be extended to
        2,500 meters early 2010, and the capacity of the Narita
        international airport will be 220 thousand movements or more par
        year (1.1 times to current capacity).

    3.  In order to handle increased traffic in the airspace over the
        Kanto district which includes Tokyo area safely and efficiently,
        JCAB has studied ideal traffic flows, airspace organization and
        ATC operational procedures for several years. At March 2008,
        JCAB finalize a draft of ATS routes, airspace configuration of
        terminal/ACC and ATC operational procedures.

1.  Overview of restructuring of the Kanto airspace

    1.  **Terminal Approach Control Area**

        1.  The Haneda terminal control area and the Narita terminal
            control area will be consolidated to a single terminal
            control area. This single terminal control airspace is
            smaller airspace than that combined current Tokyo and Narita
            airspace. The new terminal control facility is placed at
            Haneda.

        2.  As the terminal control airspace becomes small airspace and
            traffic would be increased, a sequencing function for
            arrival aircrafts to the Haneda and the Narita airport will
            be transferred to the Tokyo ACC.

        3.  The new terminal control area has two entry gates for each
            airport respectively, and each entry gate is a one-to-one
            correspondence to the runway (One gate one runway concept).
            The Tokyo ACC will provide sequencing service, and the new
            terminal control facility will provide metering service
            (establish appropriate in-trail separation for landing).

    2.  **Tokyo Area Control Center**

        1.  Six new sectors which are exclusively designed to control
            arrival/departure aircrafts of Haneda and Narita will be set
            up for the Tokyo ACC. These sectors will provide services
            both en-route ATC and sequencing function of current
            terminal ATC.

        2.  The sector A is for arrival aircrafts to the Narita airport
            from NOPAC and CENPAC. The sector C is for arrival aircrafts
            to the Haneda airport from western area of Japan. The sector
            D is for arrival aircrafts to the Narita airport from Asia.
            The sector E is for arrival aircrafts to the Haneda airport
            from the northern area of Japan, and for arrival aircrafts
            to the Narita airport from the Incheon, Beijing, Europe and
            Russia. The sector B is for arrival aircrafts to the Narita
            airport from the sector A and E.

    3.  **Implementation schedule**

        1.  JCAB is planning the project to implement step by step
            because it is a major change and impact to airspace
            configuration, routes and ATC operations. First step of the
            project is consolidation of the Haneda terminal control area
            and the Narita terminal control area. The consolidated
            terminal control facility is planned to operate from
            January 2010. At the same time, the sector A and F will be
            opened, and realign associated ATS routes.

        2.  Second step of the project is to open the sector C, D and E,
            and realign associated ATS routes. It is planned to operate
            from October 2010, it is the same time of the open of the
            fourth runway of the Haneda airport.

        3.  The last step of the project is to open the sector B, and
            realign associated ATS routes. To move to this step is
            required the approval of the local communities and other
            organization. Currently the target date of the last step is
            not determined.
