Airport Collaborative Decision Making

1. Advanced Airport Operations All Rights Reserved ACI 2021 2023-08-26

2. Airport Collaborative Decision Making Session 12

3. Objective: Participants will be able to: Understand “What is A-CDM” Identify the role of Station in A-CDM Appreciate the benefits of a Station implementing A-CDM Concept

4. A-CDM : Collaborative Decision Making A culture for all airports What is Airport A-CDM

5. Enhancing cooperation between all airport Partners Improving Decision making capabilities by sharing existing information and resources Enhancing performance and efficiency of all partners involved What is Airport A-CDM for

6. ATC Airport Operators Aircraft Operators Ground Handling Providers Service Providers ( Fuel companies , Catering etc ) Main Partners in A-CDM

7. Today’s operations is based on 3 different planning processes Airport Operations ( Airport slots agreed with airlines 6 months ago) ATC ( Flight Plans are known 03 hours before the flight) Aircraft Operators ( Flexible Planning targeting to penalize their operations to the minimum) Ground Handling Service Providers depend on airline Planning in order to allocate resources Why do we need A-CDM

8. Airport Operators are faced with airport slot discrepancies ATC Operations are faced with ATC slots non adherence Airline Operations/GHA are faced with the fact that their needs are not taken into account Problems of Airport Partners No interface between the 3 planning processes Result of parallel planning

9. Most relevant information exists somewhere around the airport in various systems but not readily available in all partners Information systems of airport partners are built independently Sometimes partners are reluctant to share information which consider commercially sensitive What is happening

10. Inefficient use of infrastructure Poor airport slots compliance Inadequate information results in poor gate and stand management Poor punctuality Inefficient fleet utilization Missed Connections (Passengers and baggage) Airport Operators Concerns

11. Apron and taxiway congestions Traffic overload Late incoming information reduces preplanning flexibility Suboptimal pre departure sequence Curfew? ATC Concerns Poor Service Level agreements Compliance Low turn round predictability due last minute changes Inefficient use of resources ( Manpower and equipment) Ground Handling Agents Concerns

12. Partners Share information ( common platform, exchange of information with other means) Data quality Predictability Achieving common situational awareness Decision Making Main Principles of A-CDM

13. Improve predictability Improve on time performance Reduce Ground Movement costs Optimize Ground Handling Resources Reduce Airport Congestion Flexible pre departure planning Reduce Taxiway and Airport Congestion Common Goals

14. Agreed relevant data should be shared between all partners involved at the right time. Data shared should be of sufficient quality to facilitate improved traffic predictability and planning capabilities for all partners involved. Decisions should be made by the partner best placed to make them. Decisions made should be shared with all other partners. How we achieve common goals

15. Target off Block Time ( not necessarily the EOBT) The time that an aircraft operator / handling agent estimates that an aircraft will be ready, all doors closed, boarding bridge removed, push back vehicle present, ready to start up / push back immediately upon reception of clearance from the Tower. (Source: Eurocontrol ) Estimate/Actual Ground Handling Time Estimate/Actual Boarding Start Time Estimated/Actual Turn Round Time Minimum Turn Round Time Schedule Off Block Time Exchanged Data - Aircraft Operator/Ground Handler

16. ATC will know when aircraft is ready and arrange pre departure sequence thus reduce apron and runway congestion Airport Operator will have information useful for gate and stand management , improve punctuality and airport slot adherence Airline/GSP share information with all the departments and allocate resources accordingly GSP has a time target and guide resources to meet it (on time performance, SLA etc ) Partners Benefits from Sharing Information from Airline/GSP

17. Estimated/Actual Taxi in time Estimated/Actual Start Up Approval Time ( Delays ) Estimated/Actual Taxi out Time Estimated/Actual Take off Time Exchanged Data - Air Traffic Control/Tower

18. Airlines optimize fleet in case delays are known well in advance, fuel and time savings GSP allocate resources depending on start up approval Airport Operators will know when aircraft will leave the stand and optimize infrastructure, reduce emissions and noise Partners Benefits from ATC exchanged Data

19. Gates and Stands Infrastructure serviceability (Fuel, Jet bridge) Possible closure of Taxiways , Service roads, Taxi links) Landside problems ( CUTE, Bomb threats, Passport Control congestion) Infrastructure impact from adverse weather conditions Airport Operator Exchanged Data

20. ATC will know how to taxi in/out an a/c if gate is known well in advance and avoid last minute changes which could cause ground traffic congestion GHA will know early enough if problems occur and estimate the delays thus allocate resources and predict Target Off Block Time which will be communicated to all Airport Operator will operationally recover in less time from adverse conditions or disruptions Partners Benefits from Airport Operator exchanged Data

21. There is no Airport standard, but efficient implementation requires that the standards used, including data conventions, are not local or proprietary to the greatest extent possible. The standards used must also satisfy the safety, security and reliability requirements, without creating an overkill situation and increasing costs unnecessarily As a minimum, agreement must be reached between all partners concerned in respect of the format and data conventions of the messages to be exchanged Exchange Data Standards

22. The A-CDM Turn Round Process Links the flight with ground segments Improves current information flows Predicts forthcoming events Turn Round Process Milestone Approach

23. The process defines a set of milestones in the aircraft turn round process, allowing all A-CDM partners to identify possible deviations from schedule Milestones are set from the planning of the inbound flight from the outstation until the take off of the flight at the subject station When milestone events do not appear as planned and no re-planning has taken place, a prompting mechanism raises alarms, which trigger the reaction of the responsible partner to provide the re-planning of the operation Turn Round Process Milestone Approach

24. Station Control is the coordinating department in Station organization Receives and disseminates information (Information Sharing) Monitor Turn round process and raises alarm in station departments Issues Target Off Block Time after receiving information from all airport partners and stations departments Establish a common situational awareness platform and sets the procedures to exchange data in station organization Monitor on time performance after A-CDM implementation The role of Station Control in A-CDM

25. There is no need to have electronic platform. If an airport doesn’t have one then establish procedures and milestones and try to exchange data with all airport partners. The role of Station Control in A-CDM Above all Collaborative Decision Making is a culture
