Helsinki-Vantaa goes A-CDM

01 Feb 2013

Helsinki-Vantaa Airport has become the sixth European airport to use A-CDM, Airport Collaborative Decision Making. At 08:00 UTC on 22 January 2013, Helsinki began the continuous transmission of DPI (departure information planning) messages to the Network Manager’s enhanced tactical flow management system.

Helsinki-Vantaa started CDM operations locally on 2 October 2012, so completing the A-CDM implementation process that started early in 2009, with the support of the Network Manager's Airport and Operational Support Units. 

As reliable as winter tyres in adverse conditions

For airport operators, the improved use of stands and gates increases efficiency. Improved traffic flows and reduced taxi times make for fewer queues at the runway and for less congestion on the apron and taxiways.

Air Traffic Control (ATC) benefits from improved runway and capacity planning. More accurate take-off time predictions lead to more accurate calculations of demand.

As for air traffic management (ATM), enhanced flow and capacity management results in better ATFM slot compliance and reduces the number of missed slots. It helps ATM develop strategies to help deal with the situation as it evolves.

Ground handlers benefit from more accurate arrival times, so they can plan better and make more efficient use of their resources.

A-CDM allows aircraft operators to have heightened awareness of the status and location of their aircraft, as well as save fuel, thanks to shorter taxi times. Better sequence information and improved in-block estimates can help them make more accurate fleet predictions.

In adverse conditions, A-CDM helps airports minimise the impact of bad weather on operations by disseminating relevant information in anticipation of disruptions very quickly - and it helps everyone recover more quickly afterwards.

At Helsinki Airport

Feedback from the first days of full implementation at Helsinki-Vantaa Airport indicates that operations are running smoothly.

The Network Manager Operations Centre (NMOC) also confirmed that the process is going well. They explained that the major beneficiaries of A-CDM are the aircraft operators because they know the exact status of their aircraft throughout the whole process. The NMOC is kept fully informed through automated message exchanges.

With all the useful information being shared, the aircraft’s departure can be anticipated more precisely - and this helps save time, especially when de-icing is needed, which it frequently is in Helsinki!

All these minutes saved per flight per year make for significant savings.

We would like to congratulate Timo Suorto, the A-CDM Project Manager, his team at Helsinki Airport and the A-CDM partners on this significant achievement.

The Network Manager’s A-CDM project team will continue to support Helsinki as a CDM airport with implementation of further improvements and general post-operations support whenever necessary.
