The Civil Aviation Authority of Vietnam (CAAV) will coordinate with relevant units to begin flight inspection and calibration at Long Thanh International Airport in southern Dong Nai province from September 26, according to the CAAV.

This is an important step before the airport starts official operation which is scheduled in early 2026.

This work will last over 10 days, using Beechcraft B300 aircraft.

These flights will primarily take place at night or in the early morning hours to utilize available airspace and minimize disruptions to commercial flight operations at Tan Son Nhat Airport in Ho Chi Minh City. In some cases, flight crews may need to carry out tasks around midnight to ensure the safety, accuracy, and objectivity of the inspection process.

The crew will conduct a series of complex flight procedures to test, calibrate, and evaluate the accuracy and stability of navigational and landing systems such as ILS/DME, PAPI, and ALS, while also performing radar calibration for systems including PSR/SSR/ADS-B. Most flights will depart from Tan Son Nhat Airport, and depending on weather and operational conditions, specific calibration maneuvers will be performed in the Long Thanh airspace.
