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:

Safety
Cost efficiency
Reduction of delay through improved airport operations and optimal en-route
Capacity
Environmental impact of aviation and fuel burn
Predictability
On-time performance
Reduce ground movement costs
Use of ground handling resources
Use of stands, gates and terminals
Use of the airport infrastructure and reduce congestion
Flexible pre-departure planning
Reduce apron and taxiway congestion
