Airport CDM – a double celebration

17 August 2017

The Network Manager is celebrating Hamburg becoming the 25th fully implemented Airport Collaborative Decision Making (A-CDM) airport – as well as the tenth anniversary of Munich implementing A-CDM and becoming integrated in the Network in 2007. That landmark event signalled the start of exchange of flight data between the Network Manager Operations Centre (NMOC, then the Central Flow Management Unit) and airports.

After a slow uptake in the early years, as is often the case with innovative new ideas, the pace of implementation quickened from 2011 and we are pleased to announce that earlier this week, Hamburg airport became the 25th fully implemented A-CDM airport. Hamburg is the 6th German fully implemented CDM airport following Munich, Frankfurt, Düsseldorf, Berlin Schönefeld and Stuttgart.

The other A-CDM airports in the NMOC network are: Barcelona, Brussels, Copenhagen, Geneva, Helsinki, London Gatwick (temporarily disabled), London Heathrow, Madrid, Milan Linate, Milan Malpensa, Oslo Gardermoen, Palma de Mallorca, Paris Charles de Gaulle, Paris Orly, Prague, Rome Fiumicino, Stockholm Arlanda, Venice Marco Polo and Zurich. By the end of 2017 NM, which supports airports implementing A-CDM, expects to integrate Lyon and Naples airports.

A-CDM brings together all the key organisations at the airport, including airlines, air traffic control, airport operator and ground handlers, to share information and make more informed decisions on improving the airport’s performance.  Data is also shared with the NMOC via Departure Planning Information (DPI) messages, thus significantly improving departure predictability. This improved predictability is an enabler for a safer and more efficient European ATM network. The A-CDM concept has been globally recognised and several airports outside Europe have adopted it.

The 25 airports currently implemented represent 34% of total departures in the European ATM network. By the end of 2019 NM expects this figure to increase to over 47%. 

Airport Departure Planning Information (DPI) implementation Status

A further 7% of ECAC departures are from 17 ‘Advanced ATC Tower’ airports, which have not fully implemented the A-CDM process but still would like to integrate into the ATM Network using a limited set of DPI messages; this figure is expected to rise to over 10% by end of 2019.

Advanced ATC Tower Implementation Status

As a complement to A-CDM and Advanced ATC Tower airports, the NMOC also outputs Flight Update Messages, which provide on time updates of the flight data to the destination airport. Currently there are 40 airports receiving these messages.
