EUROCONTROL Airport CDM has both developed and trialled a number of Airport CDM elements (see illustration) and is currently proactively encouraging other European airports to implement Airport CDM locally. Airport CDM is not just a system, hardware or software, meeting or telephone call; it involves culture change, handling of sensitive data, procedural changes and building confidence and understanding of each partners operational processes.
With the help of airport stakeholders the European Airport CDM concept has matured significantly over the years from a high level concept into a process that is delivering real operational benefits. More and more airports are currently implementing Airport CDM and being rewarded by the proven benefits.

Potential Benefits for each Partner |
• Enhanced use of existing infrastructure of gate and stands (unlock latent capacity)
• Airport Slot compliance
• Potential revenue enhancements (additional flights & passengers)
• Operational recovery in times of disruption and delay
• Airport Image (passengers perception of smooth operations)
|
|
|
|
• More accurate information for runway capacity planning for controllers
• Flexible pre departure planning
• Reduced Apron and Taxiway congestion
• Enhanced situational awareness during times of disruption and delay
|
|
|
|
• Improved situational awareness (aircraft status both home and away)
• Enhanced fleet predictability & punctuality
• Improved operational efficiency (fleet management) & reduced delay
• Reduced ground movements costs (less fuel burn)
|
|
|
|
• Increased predictability enables better planning
• Operational efficiency maximised
• Efficient use of existing resources (equipment and manpower)
• Reduced amount of ground activities performed “in a hurry”
|
|
|
|
• Accurate departure estimates enable improved demand calculation
• Benefits will grow as the number of airports implementing CDM grows
• Accurate demand calculation (improves flow & capacity management)
• Enhanced ATFM slot compliance / reduced number of wasted slots
|
|
|
|
• Reduction of delays
• Fewer missed connections
• Enhanced services during disruptions periods
|
|
|
|
• Decreased emissions and noise of taxiing aircrafts due to less waiting time in taxiways at the holding point (inbound / outbound)
|
|
|
|
CDM implementation is ongoing at various stages in a number of European airports.
The EUROCONTROL Airport CDM team can assist, in a number of ways; those airports wishing implement Airport CDM. Assistance may take the form of:
• Facilitation of meetings (e.g. Steering Group, Working Group)
• Conducting Gap Analysis survey
• Assist project manager in setting up project
• Provision of training at EUROCONTROL Training Institute, Luxembourg or locally at airport
• Provision of remote assistance (e.g. helpdesk)

A-CDM Implementation |

Enhance Airport CDM and Integration with ATM Network |
|
With Airport CDM implemented locally at an airport the next steps are to enhance the integration of airports with the Air Traffic Flow & Capacity Management (ATFCM) network and the Central Flow Management Unit (CFMU).
Exchange of real time data between airports and CFMU is operational. The accuracy of this data is proving to be very beneficial to both the CFMU and airports. The airports are receiving very accurate arrival estimates for all flights via the Flight Update Message (FUM). The CFMU is benefiting with enhanced take off time estimates in tactical operations via the Departure Planning Information (DPI) messages. A number of additional airports will enter into the data exchange with the CFMU over the coming months.
Based on the successful implementation of FUM/DPI at Munich airport (operational since June 2007) and the outcome of live trials in Zurich, Brussels, and other airports in close coordination with the CFMU, the objective is to develop incentives for all airport stakeholders to adopt the new procedures and take advantage of the proven benefits.

Further Enhancements of Airport CDM Processes |
With the rapid implementation of Airport CDM in Europe, the EUROCONTROL CDM project team are collating procedural best practice from the various airports. The objective being to enhance the generic processes found in the Airport CDM Implementation Manual. In parallel, new concepts and operational procedures will be developed and validated with all airport partners. E.g. the predictability of airport operations can be affected by landside events, such as traffic jams or security bottle necks.
The following procedures will be enhanced and harmonised:
|
- Pre-departure sequencing including start up and pushback for all flights together with the rules and processes for Departure Manager (DMAN);
- De-icing procedures both on stand and remote;
- Synchronised Data Link / Voice Clearance Delivery including CDM requirements;
- Processes for Alerts;
- CDM processes for Departure Planning Information messages (DPIs);
|
|
|
Integration of Airport CDM and DMAN (Ground Element only) |
|
Based on the results of both the ongoing and the new joint Departure Manager (DMAN) – Airport CDM validation trials in Brussels, Athens and Lisbon airports, the objective is to fine-tune the concept of Airport CDM – DMAN integration and prepare implementation guidance.
N.B. The concept of Airport CDM – DMAN integration refers to the part of the DMAN dealing with Stands / Gates and Ground Movement.
Furthermore, an initial development of a concept of operations for the integration of A-CDM, A-SMGCS and DMAN is on-going.
From the analysis of initial trials’ results from both DMAN and Airport CDM projects of EUROCONTROL, it became evident that the only way to increase the accuracy of the DMAN is to use the Target Off-Block Time (TOBT). The TOBT is fed into the DMAN, which in response proposes a Target Start-up Approval Time (TSAT) for the controller to consider. The TSAT is then fed back to the Airport CDM system to be used for planning purposes by the airport operations and the activities of handling companies.
Currently implementation of DMAN at major European airports is integrated into the Airport Collaborative Decision Making pre-departure sequencing and collaborative management of flight updates processes as described in the CDM Implementation Manual.

Standardisation of Airport CDM Acronyms and Alerts linked with Operational Processes |
From the initial drafts of the Airport CDM concept documentation until the complete Airport CDM Implementation Manual, a number of new acronyms were introduced, closely linked with the proposed CDM processes. The objective is to propose the list of key CDM processes and related acronyms to ICAO / European Air Navigation Planning Group (EANPG) for standardisation. In the mean time harmonised text for AIP publication by CDM Airports is being co-ordinated.
On the other hand, aircraft operators operating throughout Europe demand a uniform implementation of Airport CDM related processes and alert messages. As the CDM alerts (defined in the Implementation Manual) are significant for increasing the predictability, the aim was to perform trials on format, contents and exchange means of these alerts. Following the evaluation of the trials results and in close coordination with ACI and IATA, the agreed set of alert messages has been proposed for standardisation.
In addition, standard messages are under development for communication of Airport-CDM messages to the pilot via datalink.

More information about the Airport CDM project may be found on its dedicated website. On this site you will find all documents relating to the project, minutes and presentations from Airport CDM Task Force meetings plus information regarding those airports that are currently implementing Airport CDM.
