Moving towards timely and successful airport A-CDM 2.0 implementation
Velis Eleftheriou – an independent A-CDM and TAM consultant – writes that the time has come to extend A-CDM into passenger terminals and to link this essential concept with the equally important concept of passenger experience.
A-CDM focuses on aircraft turn-round and pre-departure sequencing processes
A-CDM proven benefits
Airport Collaborative Decision Making (A-CDM) has been implemented in more than 20 airports in Europe and in a handful of airports worldwide including Auckland and Singapore Changi. Implementation projects are currently underway in several airports both in Europe and beyond. Moreover, there have been some launches of national A-CDM harmonisation activities, for example in Germany and the United Arab Emirates.

The significant benefits of A-CDM for all airport partners have been proven in every airport at which the concept has been implemented. Furthermore, there are even greater benefits to be gained when more airports are linked to the national or regional air traffic management (ATM) network. In Europe, for example, a recent comprehensive study sponsored by EUROCONTROL demonstrated the benefits for the European ATM Network.
From the initial publication of the 2006 European A-CDM Implementation Manual, the concept had two specific targets: 1. To increase the predictability of aerodrome (airside) operations, which results in operational efficiency enhancements (with associated financial and environmental benefits) 2. To provide reliable estimates for the time a flight will take-off and enter the (often congested) ATM network, by monitoring the progress of the turn-around activities and identifying deviations from the schedule. What happens to an aircraft on the ground between the time at which it exits the ATM network (when landing) to the time it re-enters (when departing) used to be a ‘big unknown’. However, A-CDM filled this gap by providing the required transparency and missing predictability at the nodes of the network (i.e. the airports), enabling more efficient network management. Implementation results during the past decade have proven that A-CDM is essential to all medium and large airports worldwide that are looking to ‘sweat their assets’.
