A-CDM is understood as a unified process between the operating units at the airport. A-CDM provides a platform for units to coordinate and share information and data to serve decision-making at the airport with the aim of managing airport congestion, increasing the efficiency of operating planning, optimizing resource use, improving forecasting capabilities and improving flight punctuality.
Exploiting the A-CDM model at AOCC Center - Tan Son Nhat International Airport
Thereby, minimizing waste in slot usage and air traffic flow management; minimizing congestion on aprons and taxiways; reducing fuel consumption costs due to reduced taxi times; limiting environmental impacts, reducing noise and CO2 emissions in the airport area.
The official application of A-CDM is a very important milestone, marking the success after 3 years of research efforts of Tan Son Nhat Port and the participating parties (VATM, Vietnam Airlines, Pacific Airlines, Vietjet Air, Bamboo Airways, Vietravel Airlines, SAGS, VIAGS). At the same time, it enhances the role and position on the international platform of Tan Son Nhat, especially with the major airport in the Asia - Pacific region as well as the airport system worldwide.
Tan Son Nhat Airport representative assessed: Tan Son Nhat is the gateway airport in the southern region, the largest in Vietnam, with the highest frequency of take-offs and landings in the country (approximately 260,000 CHC). Passenger throughput through the port by the end of 2023 reached 42 million (1.5 times higher than the designed operating capacity), showing overload in infrastructure as well as operating capacity.
In addition, the existing technical infrastructure is not yet synchronized, the flight information systems are developed internally by the relevant parties (in-house), leading to difficulties in sharing information between units. The ATM flight control system in the southern region is not yet equipped with the AMAN/DMAN system (arrival/departure aircraft management system), leading to the arrangement of the order of arrival and departure at the port not being implemented, and the departing aircraft only follow the "first come, first served" method.
The first days of testing the A-CDM model at Tan Son Nhat International Airport
From those challenges, with the high determination of the Civil Aviation Authority of Vietnam, the Steering Committee for implementing the A-CDM model, Vietnam Airports Corporation (ACV), Tan Son Nhat International Airport and units operating in the port area, the implementation of A-CDM is extremely urgent, with benefits for all parties, improving the operational capacity of the entire airport.
"In December 2020, under the direction of ACV, we quickly deployed the establishment of the A-CDM model implementation team at Tan Son Nhat, including all leading experts and decision-making authority on operations from the following units: Tan Son Nhat Port, Southern Air Traffic Management Company, 5 airlines, SAGS, VIAGS and To70 Consulting Unit (Netherlands) to organize the implementation of this important task. Through all steps from document development, system development, feature testing, process scenario assessment, professional training, Tan Son Nhat Port and the units have successfully deployed 2 test rounds on daily flights, with a total of 22,441 flights, applied during off-peak/peak hours and all day 24/7 for a long time. From there, fully assessing the risks of operations and systems, is a solid and reliable legal and scientific basis for the Civil Aviation Authority to issue decided to officially deploy the A-CDM model at Tan Son Nhat International Airport from 0:01 on February 1" - Tan Son Nhat Port representative added.

The implementation of the new operation management model applied in time for the peak of the Lunar New Year 2024 is even more important, helping to significantly reduce the situation of delayed flights, causing congestion at this "hottest" airport. In the coming time, the application of the A-CDM model will continue to be monitored and developed by ACV, Tan Son Nhat Port and participating parties, investing in equipment to improve automation capabilities, reduce errors from manual operations due to human factors, improve professionalism and optimize the operation capacity of the entire airport.
The A-CDM model is a common trend of major airports in the world. Currently, in Europe, there are 32 airports that have successfully implemented it (Amsterdam, Barcelona, Berlin, Brussels, Frankfurt, Geneva, London Heathrow, Munich, Naples, Paris CDG...), 8 airports are testing the implementation. In Asia, there are also about 19 airports that have successfully implemented A-CDM such as: Changi (Singapore), Incheon (Korea); Shanghai, Beijing, Hong Kong (China), Suvarnabhumi (Thailand), and soon Kualalumpur (Malaysia), Philippines...
