A-CDM (Airport Collaborative Decision Making) is a European project that aims to improve both air traffic management and the capacity at airports.
This is achieved by reducing delays, improving the predictability of events and optimizing resource utilization.
In this context, A-CDM objectives are:
• Increase resource efficiency
• Improve the punctuality
• Improving the performances of the ATM network
Decision making by the actors from the airport is facilitated by the sharing of accurate and timely information and the adoption of new procedures, mechanisms and tools.
To do this, significant events (milestones) on flight progress are defined to provide relevant information.
• Airlines: Improving compliance program, prioritization ability.
• Handling agents: Improved predictability of operations, better use of resources.
• Airport: Improving punctuality, more efficient use of stands, gates and terminals.
• Air Traffic Control: Optimizing the use of air-side, reducing congestion.
• CFMU: Bigger compliance with the slots, optimize the use of airspace capacity.
Iberia has been working for more than two years very closely with AENA defining new operational procedures, designing the ACDM systems and it´s algorithms.
At the same time Iberia airport services has started many different actions to guarantee a secure and transparent migration for all her clients. Some of the actions have been:
• Specific training for flight dispatchers and hub control allocators
• Internal communication
• ACDM brochure for pilots OCC departments with FQS and good practice recommendations
• Support and additional training for airlines who request so
• Briefings to subcontractors
• Modification, improvement and system adaptations
The adaptation or test phase is divided in two:
PHASE I or familiarization and incidence correction PHASE The duration is of 4 weeks, extensible to more if needed. Dairy trials from Monday to Thursday, during three hours a day during different selected peaks all the airlines work under ACDM procedures. There will be no penalties for those companies who do not comply with ACDM parameters, at star-up request TWR will inform about the noncompliance to the crew.
PHASE II Duration of three weeks. Dairy trials from Monday to Thursday during four hours per day (2 weeks), twelve hours per day (one week) during different selected peaks all the airlines work under ACDM procedure. In this case airlines that not comply with ACDM procedures will be penalized.
Last Octuber 7th Madrid Barajas airport has started with ACDM trials on PHASE. The first impressions and data analysis have been very positive.The TSAT (Target Star-Up Approval Time u hora objetivo de puesta en marcha) and TOBT (Target Off-Block Time u hora objetivo de salir de calzos) accomplishment by IBAS clients have been nearly of a 100% above the average. Punctuality was also above the daily average for those peaks.
