Starting from 01 Feb 2024, Tan Son Nhat International Airport (SGN) officially implemented the Airport Coordinated Decision-Making model (A-CDM), which has increased the punctuality of take-offs and landings.
Applying the A-CDM technology model helps passengers experience flights with high on-time rates, minimizing situations where aircraft stop for long periods on taxiways during Lunar New Holiday.
This is a very important milestone, marking success after 3 years of efforts by SGN and participating parties such as airlines, ground services, flight management… SGN has officially become a part of the global and regional map of airports implementing the Airport Coordinated Decision-Making (A-CDM) model.
What is A-CDM technology?
According to SGN representative, A-CDM (Airport Collaborative Decision Making) is understood as the agreed process between operating units at the airport.
A-CDM provides a platform for various units to coordinate, share information, and make data-driven decisions at airports.
The goal is to manage congestion at the airport, increase operational planning efficiency, optimize resource use, predictability and improve flight punctuality.
This model helps minimize the wastage of slot usage and improves air traffic flow management. It reduces congestion on aprons and taxiways and cuts down fuel consumption costs by reducing taxiing time…
Currently, SGN is “working hard” to exploit beyond its designed capacity. In 2023, the frequency of takeoffs and landings at this airport will be approximately 26,000 with 42 million passengers, one and a half times the designed operating capacity.
In addition, the existing technical infrastructure is not synchronized, flight information systems are developed internally by relevant parties, leading to difficulties in sharing information between units.
Furthermore, the flight control system in the southern region lacks a management system for coordinating aircraft arrivals and departures. This leads to a lack of planning for the sequence of arrivals and departures at the airport, resulting in flights being handled on a ‘first come, first served’ basis.
When applying A-CDM, SGN representative expects efficiency and benefits to help facilitate flight coordination activities and limit flight delays. Officially applying it during Tet is a necessary solution during peak travel periods.
Currently, the A-CDM model is a common trend at major airports in the world.
For example, in Europe, there have been 32 airports successfully deployed (Amsterdam, Barcelona, Berlin, Brussels, Frankfurt, Geneva, London Heathrow, Munich, Naples, Paris CDG…), 8 airports are testing implementation.
In Asia, there are also about 19 airports that have successfully deployed A-CDM such as Changi (Singapore), Incheon (Korea), Shanghai, Beijing, Hong Kong (China), Suvarnabhumi (Thailand), and the upcoming Kuala Lumpur (Malaysia), etc.
