CANSO Drives CDM Initiative in the Asia-Pacific Region

Barely two months after its inaugural June meeting to kick start its first CDM project and a teleconference in July, CANSO has convened a second meeting on 24-25 August 2011 in Singapore to push ahead with its plan to improve ATM performance between major city pairs in the region.
A joint endeavour of the CANSO Asia-Pacific Office and the Operations Standing Committee (OSC), the Collaborative Decision Making (CDM) project is a first in the region involving a major city pair. The pilot project for flights between Singapores Changi Airport and Bangkoks Suvarnabhumi will demonstrate the efficiency gains achievable through the integration of airport and en-route CDM and will establish best practices for other city pairs in the region.

The meeting in Singapore was facilitated by Greg McDonald of Airservices Australia, a member of the OSC and co-chaired by Rosly of CAAS and Piyawut of AEROTHAI. Comprising experts from the airports, airlines and ANSPs of Thailand and Singapore, the project team was joined by colleagues from DCA Malaysia led by its deputy director for ATM Mr Nathan. As the intermediate ANSP for flights between the city pair, DCA Malaysia plays a key role in the en-route CDM process and its participation at the meeting shows its support for seamless ATM operations in the region.

The two day meeting delved into the detailed information required by each stakeholder for each phase of flight - a process decribed by one participant as a group of blind men describing an elephant depending on where they touched! The paintstaking process was nevertheless crucial in helping participants see each others viewpoints and help establish a common understanding of the pilot project and the information to be shared among the airports, airlines and ANSPs. In discussing the objectives of the project the meeting agreed that apart from an overall improvement in ATM performance for the city pair, the application of CDM should lead to better on-time performance for the airlines and reduced congestion at the airports. This means better use of resources for airports, airlines and ANSPs and quantifiable savings in fuel consumption and carbon emissions for the thousands of flights operating on the city pair.

The CDM meeting in Singapore made good progress but to keep the momentum going, the project team agreed that it was necessary to meet again in November 2011, this time in Bangkok. In the meantime, the project team will work via teleconference and email on the follow up action.
