CIVIL AVIATION BUREAU of JAPAN Ministry of Land, Infrastructure, Transport and Tourism The proposal for the analysis of international air traffic flow control among EATMCG THE EIGHTH MEETING OF THE INFORMAL EAST ASIA AIR TRAFFIC MANAGEMENT COORDINATION GROUP (EATMCG/8) (Hong Kong, China, May 2015)

Civil Aviation Bureau of Japan Ministry of Land, Infrastructure, Transport and Tourism 2 Introduction ✈ As our common report shows, the air traffic in East-Asia region has been increasing steadily. In consequence, international ATFM has been implemented more frequently. ✈ Although it is important to manage ordinary operations, it is also essential to recognize the gap between the present ATFM and the ideal ATFM. ✈ In order to achieve the mentioned above, ANSPs should make up the scheme of data exchanges and post- operations analysis to review and enhance the flow controls. It also leads to practical CDM. Introduction

Civil Aviation Bureau of Japan Ministry of Land, Infrastructure, Transport and Tourism 3 Proposals ✈ The concept ✈ The data provided by each state ✈ How to utilize the data ✈ Demand and capacity balancing

Civil Aviation Bureau of Japan Ministry of Land, Infrastructure, Transport and Tourism Example 1 : The present flow control for RCTP RJAA VHHH RPLL RCTP RJFF RJBB RJGG RJCC RJFK RJOA/OB From North America In case of A1 (for RCTP) PERIOD: 0200z-0700z MEASURES: 40MIT RALT Reference DATA ETD / ATD / OVER TIME OF BULAN (it is ideal to apply the following data) ETA, ATA, en-route DLA, Actual number of arrival, and so on In case of A1 (for RCTP) PERIOD: 0200z-0700z MEASURES: 40MIT RALT Reference DATA ETD / ATD / OVER TIME OF BULAN (it is ideal to apply the following data) ETA, ATA, en-route DLA, Actual number of arrival, and so on BULAN RJNT/NW
