ATC
Asia Pacific Countries Taking ATM Initiative
Japan’s solution to airspace congestion is CARATS (collaborative action for renovation of air traffic systems), which shifts from sectorized airspace to trajectory-based operations, managing flights on an end-to-end basis. Tests were recently completed using CARATS for 4-D trajectory approaches at Tokyo’s Haneda Airport.

Facing the demands of increasing air traffic capacity and operational efficiency, the countries of the Asia Pacific region have launched various programs to adopt recent advances in Air Traffic Management and advances inavionics technology over the past couple of decades. Some countries (notably Australia) have forged ahead, while others are further behind, but it is hoped that recent developments could see closer cooperation for an eventual move to a whole-area solution.
