Report on Japan’s Airspace Redesign Plan

THE 46th MEETING OF INFORMAL PACIFIC ATC CO-ORDINATING GROUP (IPACG/46)

Presented by JCAB Oct.2020

Ministry of Land, Infrastructure, Transport and Tourism Outline of airspace reorganization

Overview

In order to respond to the increase in air traffic volume, we will carry out domestic controlled airspace (ACC and approach control area) changes in stages.

【ACC:area control center】 We’ll divide the domestic controlled airspace (ACC) into upper and lower parts. High altitude sector・・・・・for cruise aircraft Low altitude sector・・・・・for short-range flight, climbing / descending aircraft around the airport

【approach control area】 We’ll integrate multiple approach control areas, then we centralize the processing of aircraft climbing/arriving at nearby airports.

We will increase the number of aircraft that can handle air traffic control by improving the efficiency of air traffic control processing. 2 4 ACCs operating S04
