Airport Collaborative Decision Making (A-CDM) System

Airport Collaborative Decision Making (A-CDM) System

Syllabus subtopic: Infrastructure: Energy, Ports, Roads, Airports, Railways etc

Prelims and Mains focus: about A-CDM and its benefits

News: Guwahati has become the eighth Indian airport to implement an Airport Collaborative Decision Making (A-CDM) system.

About A-CDM

  • The A­CDM system uses aircraft's expected time of arrival, runway­in­use and runway handling capacity among other factors to determine the aircraft's arrival and departure sequence.

  • The system improves the performance of airport operations and ensures a smooth arrival and departure sequence for airlines.

  • Airport CDM (A-CDM) is about partners (airport operators, aircraft operators/ground handlers, ATC and the Network Operations) working together more efficiently and transparently in the way they work and share data. The efficiency of the Air Transport System is highly dependent on traffic predictability.

  • The Airport CDM project aims to improve the overall efficiency of operations at an airport, with a particular focus on the aircraft turn-round and pre-departure sequencing process.

  • One of the main outputs of the CDM process will be more accurate Target Take Off Times which can be used to improve en-route and sector planning. This is being achieved through the implementation of a full set of Departure Planning Information messages (DPIs) sent to Network Operations. The advantages of the network will start to multiply as more and more airports implement A-CDM.

Possible benefits of A-CDM:

  1. Safety
  2. Cost efficiency
  3. Reduction of delay through improved airport operations and optimal en-route
  4. Capacity
  5. Environmental impact of aviation and fuel burn
  6. Predictability
  7. On-time performance
  8. Reduce ground movement costs
  9. Use of ground handling resources
  10. Use of stands, gates and terminals
  11. Use of the airport infrastructure and reduce congestion
  12. Flexible pre-departure planning
  13. Reduce apron and taxiway congestion
