Flights from HCMC increase on-time takeoff and landing rates
(Dân trí) – Tan Son Nhat International Airport has implemented a new model in its operation, leading to a 20% increase in on-time flight performance and reducing waiting time for passengers.
According to a report from Tan Son Nhat International Airport (TSN), after a week of testing the A-CDM model on 212 inbound and 249 outbound flights, the results showed a positive impact on operational efficiency.
After a week of testing the A-CDM model on 212 incoming and 249 outgoing flights, the airport achieved positive results in operational efficiency. Specifically, the rate of flights that were on time, as regulated by the Vietnamese Civil Aviation Authority, was 96.9%, a significant increase from the same period in March 2022, which was at 72%.
The rate of adherence to flight times being delayed (off-block) met the target of the two ground service providers (SAGS, VIAGS) and domestic airlines at 95.1%.
The rate of adherence to the permitted engine start-up time was 80%.
With these initial successes, Tan Son Nhat International Airport will continue to test the A-CDM model for international flights, adding approximately 53 international airlines that operate at the airport.
On March 16, the airport held a meeting to coordinate preparations for the A-CDM testing, attended by leaders from the Vietnam Airports Corporation, the Vietnam Air Traffic Management Corporation, the Saigon Ground Services Company, the Vietnam Airport Ground Services Company’s Tan Son Nhat branch, the Southern Airports Authority, the Air Traffic Flow Management Center, and representatives from domestic airlines.
The plan is to test phase 1 of the A-CDM model at Tan Son Nhat International Airport from March 27 to April 27. After completing the testing, the airport will evaluate and report on the feasibility of the process, preparing to implement the new model for daily operations.
According to the explanation of the A-CDM implementation plan, the full name of the new model is the Airport Collaborative Decision Making system. A-CDM will solve many problems that airports are currently facing.
Tan Son Nhat Airport has a large transportation volume and is designed to serve 28 million passengers per year. However, according to the report of Tan Son Nhat International Airport, as of December 31, 2022, the total number of passengers through the airport was 34.2 million passengers per year, exceeding the designed capacity of the airport by 22%.
Due to the overcrowding situation and the separate operations of units, the current procedures cannot be optimally exploited, leading to many cases of disruption of departure order; many planes have to queue for takeoff and landing; there is no optimal plan for sharing information about the turnaround process of airplanes and real-time flight delays between airlines, ground handling units, airports, and flight management units.
The new model is expected to bring passengers flights with high on-time performance, limit circling to wait for landing, reduce planes waiting for a long time on the runway, and provide better baggage and cargo services.
Moreover, based on the assessment of air transportation demand and service capacity of units, while meeting the travel needs of the people, the Civil Aviation Administration of Vietnam decided to increase flight slots at Tan Son Nhat International Airport on the occasion of the 30/4-1/5 holiday and the peak season of summer 2023.
Accordingly, from April 28 to May 3 and the peak season of summer (from June 1 to August 15), Tan Son Nhat airport will add 26 slots/day, equivalent to supplying an additional 4,500-5,000 seats/day from airlines.
The Civil Aviation Administration of Vietnam also requested airlines to operate flights on time, limit flight delays, and service providers to develop plans to serve flights during peak periods.
A-CDM (Airport Collaborative Decision Making) is defined as the process of coordination between units to make decisions at the airport. A-CDM provides a common software platform for coordinating units to share information and data to support decision-making at the airport.
According to statistics from the International Civil Aviation Organization (ICAO) and the Airports Council International (ACI), A-CDM has been widely adopted at many advanced airports worldwide such as Changi (Singapore), Incheon (South Korea), Suvarnabhumi (Thailand), Shanghai, Beijing, Hong Kong (China)…
