The aviation surveillance system at Long Thanh airport meets ICAO technical requirements.

After 5 hours of calibration flights, it was shown that the aviation monitoring system at Long Thanh airport fully meets the technical requirements according to the standards of the International Civil Aviation Organization (ICAO) and the Civil Aviation Authority of Vietnam.

On October 26, Vietnam Air Traffic Management Corporation (VATM) chaired and organized the second phase of technical calibration flight at Long Thanh airport using Beechcraft B300 aircraft (OK-ANS).

Accordingly, flight calibration activities for aviation surveillance systems include primary/secondary radar (PSR/SSR) and automatic dependent surveillance-broadcast (ADS-B) systems.

Air Traffic Management Engineering Company Limited (ATTECH) undertakes, coordinates with Southern Air Traffic Management Company, Long Thanh Airport Project Management Board, and international contractors to conduct flight calibration.

There is also the participation of experts from the Czech Republic Air Navigation Academy, along with a team of experienced Vietnamese engineers and air traffic controllers.

This time, Beechcraft B300 aircraft (OK-ANS) was selected for calibration flight, including 30 flights with strict technical requirements.

Specifically, the three orbital flights aimed to test the radar's horizontal coverage at radii of 10-20 nautical miles (equivalent to 18.52-37.04 km), altitudes from 5,000-10,000 feet (equivalent to 1,524-3,048 m).

4 flights following the arrival (STAR) and approach (IAP) procedures at both ends of runway 05R/23L to test the surveillance capability of the ADS-B system. In addition, there were 23 flights to test the vertical coverage area…

Throughout the flight, air traffic controllers, approach controllers and the air traffic control tower coordinate smoothly, maintain safe separation, and ensure smooth and accurate flight operations down to the last detail.

In addition, aviation meteorologists continuously update weather conditions, support flight crews and radar stations in optimizing calibration phases, ensuring measurements are performed under the best conditions.

After 5 hours of continuous work (from 4:20 a.m. to 9:40 a.m. on the same day), the calibration flight ended in absolute safety.

Initial results show that the aviation surveillance system at Long Thanh airport operates stably, with clear surveillance signals, high coverage and accuracy, fully meeting the technical standards of the International Civil Aviation Organization (ICAO) and the Civil Aviation Authority of Vietnam.

Data collected during flights will be compiled, processed and handed over by ATTECH to Long Thanh Air Traffic Control Tower to serve radar display calibration work, integrated into VATM's national monitoring network.

Calibration flight of landing support and navigation systems at Long Thanh airport

Previously, on September 26, VATM also chaired and coordinated with relevant units to organize a calibration flight of a series of important systems at Long Thanh airport, including two ILS/DME precision landing support systems, a VOR/DME navigation system, an airport lighting system, radar and ADS-B surveillance systems; and flight methods related to the above equipment.

The flight is to test, evaluate, ensure the accuracy and integrity of equipment systems ensuring flight operations according to standards prescribed by the International Civil Aviation Organization (ICAO) and assess the suitability of new flight methods.
