In order to replace the outdated Instrument Landing Systems (ILS) and related facilities in the Taipei Flight Information Region (FIR), and to ensure the stable operation of the landing systems at various airports in the region, Air Navigation and Weather Services (ANWS) plans to implement a "single procurement, executed over several years" approach from 2025 to 2029. Over five years, the ANWS will gradually replace the navigational aids and related auxiliary facilities that have exceeded their service life. The plan includes the procurement of 10 sets of Instrument Landing Systems (ILS), 2 sets of Localizer Directional Aids (LDA), 12 sets of Distance Measuring Equipment (DME), and one ILS/DME training simulator. The "unified procurement" approach will provide significant benefits by standardizing equipment performance and parts. This will simplify logistics, reduce inventory, unify training materials, and streamline maintenance and repair procedures. Most importantly, after standardizing the equipment, it will facilitate the interchangeability of avionics maintenance personnel, optimizing the use of human resources and directly or indirectly improving the operational efficiency and reliability of the equipment, thereby ensuring flight safety.

This plan will be implemented from 2025 to 2029, with a budget allocation of NT$474,342,000. It is planned that in Year 115, one complete set of ILS/DME equipment for Runway 05R at Taoyuan International Airport, one complete set of LDA/DME equipment for Runway 03 at Nangan Airport, and one complete set of LDA/DME equipment for Runway 04 at Taitung Airport will be procured and installed.

Pursuant to the Taoyuan International Airport Park Master Plan, Taiwan Taoyuan International Airport is actively advancing the northern airport expansion program, which includes the construction of a third runway. The existing Northern Terminal Area Surveillance Radar is currently located within the planned site for the future satellite concourse. To prevent any adverse impact on the Airport’s overall development, relocation of the radar system is therefore imperative. In addition, the Northern Terminal Area Surveillance Radar has been in operation since 2005 and will have exceeded 20 years of service by 2025, surpassing its designed service life of 15 years. Although the Air Navigation and Weather Services have undertaken enhanced maintenance measures—including increased maintenance frequency, sourcing alternative components, and engaging both domestic and international vendors for repair and technical support—to extend the system’s operational lifespan, certain critical components have been discontinued by the original manufacturer. Consequently, the radar system faces increasing challenges in securing replacement modules, along with escalating maintenance costs.

This project will be implemented from 2025 to 2028, with a total budget of NT$436,279,000. In 2026, it is planned to complete the radar system design review, equipment manufacturing, and factory training. Construction of the North Terminal Area Control Radar Park at Taoyuan International Airport is expected to be completed by November 2027. The replacement of the North Terminal Area Control Radar at Taoyuan International Airport is scheduled for completion by July 2028, with the new radar system planned to commence operation in November 2028. Upon commissioning, the system will meet the future development needs of Taoyuan International Airport and enhance aircraft surveillance and air traffic control operations.

Air Traffic Flow Management (ATFM) refers to the management of air traffic flows to ensure that aircraft can operate safely and efficiently in congested airspace and airport areas. By fully utilizing capacities of airport airside, runway, and airspace, the departures, arrivals, or boundary-point passage times of flights are managed to achieve the objectives of improving operational efficiency, reducing airborne holding, and promoting energy conservation and carbon reduction.

ANWS has formulated the “Taipei Flight Information Region Air Traffic Flow Management 5-Year Development Plan,” which is being implemented in two phases. The first phase (2023–2024) has already extended the trial operation of Calculated Take-Off Time (CTOT) to the region’s major international airports and completed the establishment of the ATFM platform, initially establishing airport and boundary-point flow management functions. The second phase (2025–2027) covers the following implementations and subsequent plans:

1. An ATFM system was independently developed and built with innovative features. Airport and boundary-point functions have been completed. In 2025, the system received the Ministry of Transportation Integrity Exemplar Award. In addition, the ATFM Portal web-based public platform and its mobile version were designed and developed to provide real-time flow management information to stakeholders.
2. In 2025, 14 ATFM briefing sessions were held. Proactive exchanges and discussions were conducted with stakeholders, including airlines and airport authorities. From 25 to 30 September of 2025, ATFM trials were conducted with Hong Kong, Japan, Thailand, Korea, the Philippines, Singapore, and Vietnam. The trials were successful. It is planned that flow management position operations will officially commence in mid-March of 2026. Through the implementation of flow management measures, the balance between airport/boundary-point capacity and demand will be ensured, thereby enhancing air traffic control operational safety, reducing airborne holding, and achieving energy conservation and carbon reduction.
3. In 2026, the development of airspace flow management functions and the training of flow management personnel will continue. Communication with stakeholders on ATFM operational practices will also be strengthened to ensure effective implementation of flow management measures. The goal is to integrate flight information from the regional air traffic control system and establish a flow management operational platform that balances aviation traffic capacity.

Project Overview and System Upgrades:

To establish a new-generation aviation weather information system that meets the operational and service needs of this region while aligning with international development trends, the Air Navigation and Weather Services (ANWS) has completed the "Advanced Operational Aviation Weather System Renewal and Update (AOAWS-RU)" project. This project encompasses two main tasks:

First, through the "Taiwan-US Technical Cooperation Agreement on the Development of the Advanced Operational Aviation Weather System," the US National Center for Atmospheric Research (NCAR) was commissioned to develop weather forecasting algorithms. This facilitated the introduction of advanced US forecasting algorithms for icing, turbulence, visibility, ceiling height, cloud top height, and thunderstorms.

Second, domestic vendors were commissioned to build the new-generation aviation weather information system. This infrastructure includes a Data Center, a Forecasting System, a Typhoon and Wind Forecasting System, a Monitoring and Management System, and the New-Generation Aviation Weather Service Web Portal.

Transition Preparation and Timeline:

To ensure a smooth system transition and commissioning, a cross-departmental transition working group was established. This group was responsible for drafting transition plans, revising documentation, and carrying out preparatory tasks encompassing change management and transition procedures. Three briefing sessions for internal and external users were held in January 2026, with the system officially scheduled for commissioning on March 18, 2026.

Expected Benefits and Future Outlook:

The outcomes of this project will yield substantial practical benefits. These include achieving integration with the ICAO System Wide Information Management (SWIM) framework, enhancing the overall quality of aviation weather forecasting services, improving user convenience, strengthening system monitoring mechanisms, and ensuring robust system security and stability.

In light of the increasingly severe cybersecurity threats, including targeted social engineering, ransomware, and theft of confidential information both domestically and internationally in recent years. ANWS bears the critical responsibility of national air traffic control. To prevent cybersecurity incidents from impacting national security and economy, ANWS continues to strengthen its protective capabilities in accordance with the “Information Security Enhancement Roadmap”. The long-term plan for 2026-2027 aims to enable critical information and communication systems to establish their own cybersecurity defense mechanisms, thereby implementing proactive defense and ensuring the safe operation of critical infrastructure.

To ensure a seamless transition of air traffic control services upon the end of service life of the existing Air Traffic Management System (ATMS), to accommodate future air traffic growth as well as emerging operational needs and evolving technologies, and to comply with international standards such as the ICAO Global Air Navigation Plan (GANP) and the Aviation System Block Upgrades (ASBU) framework, the Air Navigation and Weather Services (ANWS) developed Next-Generation ATMS Implementation Plan. The plan also includes the expansion of the facilities at Northern and Southern Air Traffic Services (ATS) Parks.

Through the integration of advanced technologies into the new system, ANWS aims to continuously deliver high-quality air traffic services, align with international standards and practices, and maintain Taipei FIR’s competitiveness and leading position within the Asia-Pacific region.

Following preliminary planning conducted from 2020 to 2023, the Implementation Plan has been submitted for administrative review and is targeted for approval in 2026. The project comprises two major components:

1. Expansion of the North and South ATS Parks: Civil engineering design is scheduled for 2027, with construction activities planned for the period from 2028 to 2032.
2. Next-Generation ATMS: System requirements definition is scheduled for 2027, followed by system tendering in 2028. System development, installation, and implementation are planned for the period from 2029 to 2034.

In response to the expanded airfield area and anticipated growth in traffic volume following completion of the third runway at Taoyuan International Airport, ANWS plans to construct a second control tower between the third runway and the existing runway 05L/23R. In addition to providing air traffic control services, the two towers will be interoperable in terms of controller working positions and automation systems to provide mutual backup, thereby enhancing operational resilience and delivering more comprehensive air traffic services.

In accordance with the airport's third runway construction timeline, ANWS began the Second Air Traffic Control Tower Construction Preliminary Plan in 2021. This involves assessment of suitable locations and heights for the second tower, as well as planning the necessary facilities to support air traffic control. Having considering the objectives, implementation strategies, timelines, and budget estimates, while also conducting risk management, the construction plan is finalized and submitted for administrative processes.

ANWS plans to secure administrative approval in 2026. The construction project is scheduled to commence in 2027, detailed design and contractor tendering are scheduled for 2028, followed by construction from 2029 to 2032. Installation of systems and equipment, along with integrated testing in close coordination with the third runway is planned for 2031 to 2033.

Objective:

To accommodate the construction of the third runway at Taoyuan International Airport, the operational coverage area of the existing Low-Level Wind Shear Alert System (LLWAS) must be expanded accordingly. Furthermore, as the current system is approaching the end of its service life, a next-generation system is being planned to reduce maintenance costs and align with the latest international remote sensing technologies for wind shear detection.

This project aims to ensure the continued provision of real-time low-level wind shear alert services at the airport, thereby safeguarding aviation safety.
