Airport CDM
in action
By 2030 there will be around 20 million flights a year in Europe. Ian Goold looks at how airports can avoid congestion through processes such as Airport Collaborative Decision Making
 
In June 2007, Munich
became the first European
airport to fully implement
Airport Collaborative Decision Making (A-CDM) as a standard procedure, following concept trials from July 2006. With partner DFS, the German Air Navigation Service Provider, the airport focused initially on improving aircraft turnarounds and the establishment of a pre-departure sequence, based on target startup-approval and off-block times through the sharing of information with airlines, handling agencies and EUR0C0N¬TR0L's Central Flow Management
Unit (CFMU).
The Munich A-CDM is seen as a low-cost project yielding substantial improvements. Enhancements to opera¬
 
tions include a one-minute reduction in average taxi times and the fuel saving to Airlines alone is estimated at €2.65 mil¬lion per annum.
There is also improved co-ordination between scheduled off-block time and that estimated by Air Traffic Control based on known A-CDM information, while calculated take-off times based on CDM information are generally better than esti¬mated solely from flight-plan data. Average take-off delays are down from 3.3 to 1.3 minutes and there is improved adherence to traffic-flow management slots.
Buoyed by the success of A-CDM, the airport (Munich FMG) and DFS are plan¬ning to upgrade A-CDM to accommodate the new third runway and additional apron areas, and to optimise departures even further with more-precise arrival-demand forecasts.
A-CDM STAKEH0LDERS
A-CDM was launched by EUR0C0NTR0L as a concept within the Airport Pro¬gramme in 2002. It aims to establish continuous communication among all interested parties, allowing them to make the correct operational business deci¬sions. Potential partners include: airport and aircraft operators, ground handlers, Air Navigation Service Providers, support-service providers and EUR0C0NTR0L's own CFMU. EUR0C0NTR0L says A-CDM accommodates partners' preferences and constraints relative to any "actual
and predicted situation" — whether driven by, for example, technical, operational or meteorological circumstances.
The concept enhances partners' abili¬ties to manage through the sharing of accurate and timely information and
by adapted procedures, mechanisms, and tools. The value of A-CDM can be understood in light of the Agency's Chal¬lenges of Growth study, the latest edition of which highlights long-term airport-capacity considerations facing the region as the European Air Traffic Management (ATM) network continues to expand.
The report predicts that demand for air services will potentially double to more than 20 million flights by 2030,
 
despite current economic and industry upheaval. A lack of airport capacity is forecast to result in some 2.3 million flights being "un-accommodated" and at least 19 European airports being fully saturated. The study warns that with
one in every two flights scheduled to use one of these hugely congested airports, delays could skyrocket. The forecast means it is essential for the industry to adopt all available means of enhancing traffic flow at all points in the system, including airspace and airports.
The key to achieving this lies in establishing and maintaining maximum operational efficiency in handling each arrival, turnaround, departure (includ¬ing taxi time and take-off sequence) and en-route management to the next destination. Put another way, A-CDM aims to improve airport traffic flow and capacity management by minimising delays, improving punctuality all round and optimising use of infrastructure and resources (both manpower and equip¬ment). It covers the period from three hours before an aircraft's estimated off-block (that is, gate-departure) time and take-off, including flight planning and the whole ground process between landing and departure. 0ne way to maintain efficiency throughout the air-transport system is through access to, and use of, a common information platform that allows each stakeholder to be aware of issues faced by any other. The essential data-sharing required to ensure common situational awareness has driven the development of the A-CDM concept.
