Unlike regular transport aircraft, the calibration aircraft performs specially designed flight paths to check the technical parameters of the navigation and signal light systems. The aircraft approaches along the runway axis, flies along a defined trajectory, or performs maneuvers to assess the coverage and accuracy of the equipment.

This technical step evaluates the operational capability of the systems supporting navigation, approach, and landing, contributing to the completion of Long Thanh Airport's operational conditions.

During this phase, the Flight Inspection and Calibration Center, part of Air Traffic Management Engineering Company Limited, used a Beechcraft B300/B350 aircraft to inspect the systems serving runway 05R/23L.

On 12/10, the aircraft tested the instrument landing system/distance measuring equipment (ils/dme), precision approach path indicator (papi) lights, and radio navigation system. On 13/10, flights continued to focus on the ils/dme system and approach lighting system (als).

These systems perform different functions. Ils/dme provides guidance and distance information, helping the crew determine the runway approach path. Papi lights assist pilots in recognizing the approach angle through light signals. The als system helps pilots identify the runway and orient themselves when transitioning to the visual approach phase.

Through these flights, specialized personnel collected data to assess the accuracy and operational capability of each system under real conditions. The results form the basis for further refining the technical conditions for flight operations at the new airport.

To support the flight phase, Long Thanh Air Traffic Control Center deployed air traffic controllers, technical staff, and management personnel. Facilities, equipment, coordination plans, and contingency procedures were reviewed before implementation. Air traffic control personnel checked flight plans, operational areas, communication methods, and coordination plans among operating facilities. Tan Son Nhat Approach Control Center and Long Thanh Air Traffic Control Center maintained information exchange during the reception, control, and transfer of aircraft control responsibilities according to the approved plan.

Calibration flights require controllers to thoroughly understand the content of each flight profile, maintain continuous communication, and coordinate precisely with the flight crew and ground technical units. At Long Thanh, technical personnel reviewed the operational conditions of the aerodrome control tower, vhf radio communication system, recording equipment, meteorological information system, power supply, and essential facilities.

The inspection aims to assess the operational capability of each piece of equipment and actual service conditions. This forms the basis for units to compile data and perform subsequent technical steps as regulated.

Aeronautical meteorological work was also prepared synchronously. Tan Son Nhat Aeronautical Meteorological Center deployed one leader and two staff members to provide meteorological information for the flight phase. Three other staff members participated in practical training at their workstations, simultaneously performing duties and preparing human resources for Long Thanh Airport's operational phase. Deploying meteorological personnel at the new airport helps meet the requirements for providing information to support flight operations, while also allowing staff to familiarize themselves with the working environment, coordination procedures, and actual operational conditions.

According to a representative from Vietnam Air Traffic Management Corporation (VATM), calibration flights are a necessary technical step before putting navigation and signal light systems into operation. The evaluation results help determine the extent to which equipment meets technical requirements, thereby completing conditions according to professional procedures. This process also helps review coordination plans among air traffic control facilities, technical conditions, and the readiness of air traffic control and meteorological personnel at Long Thanh.

Airfield security and safety measures were implemented concurrently. Long Thanh Air Traffic Control Center coordinated with the Long Thanh International Airport Project Management Board to control personnel and vehicles moving from the taxiway into the runway area, ensuring all forces complied with regulations.

VATM will continue to coordinate with Airports Corporation of Vietnam (ACV) and relevant units to complete conditions for ensuring flight operations, enhancing the readiness of operational, technical, and meteorological systems. The goal is to bring Long Thanh Airport into safe and efficient operation as planned.

Long Thanh Airport spans approximately 5,000 hectares, with a total investment of nearly 16 billion USD. Phase one includes one runway and one passenger terminal, with a design capacity of 25 million passengers and 1,2 million tons of cargo annually. The airport is expected to commence operations by late 2026.

Once operational, Long Thanh, along with Tan Son Nhat, will serve as an aviation gateway for the Ho Chi Minh City region, helping to relieve pressure on the existing airport and expanding capabilities for international flights and cargo transport.
