Air Navigation Services Modernisation

The Civil Aviation Authority of Singapore (CAAS) announced a S$4 billion, 15-year “man-machine-method” upgrade for Singapore's air navigation services on 22 July 2026. The programme is intended to meet rising air-travel demand, prepare for Changi Airport Terminal 5 and strengthen safety, efficiency and resilience in the airspace managed by Singapore (CAAS, 22 July 2026). It is an air-navigation capability programme, not the construction of Terminal 5 itself and not a new airline or airport operator.

Workforce and professional pipeline

CAAS reported that its air traffic control officers (ATCOs) manage about 2,000 flights a day, including about 1,000 into and out of Changi. It plans to grow the current workforce of about 500 ATCOs by roughly 40% to around 700 by the mid-2030s. Measures announced in July 2026 include a S$20,000 sign-on bonus for new ATCO recruits from 1 June 2026, an ATC undergraduate scholarship, an ATC degree specialisation under development with a local university, and an ATC Management Associate Programme planned for August 2026. The professional training pathway remains separate from the later degree and scholarship details that CAAS says will be announced subsequently (CAAS, 22 July 2026).

Engineering, research and systems

CAAS said it will establish an Engineering Development Centre to customise, enhance and operationalise air-navigation systems with industry and research partners. It is also supporting air-traffic-management research, including a stipend top-up for local PhD students under an NTU Research Scholarship scheme. On the systems side, CAAS plans to progressively replace or upgrade more than 30 air-navigation systems, using technologies such as AI to support ATCO decision-making. CAAS says the centre will build local expertise and system resilience, but its detailed operating model had not been published on the announcement page (CAAS, 22 July 2026).

This means the engineering strand covers both capability development and research translation: the announcement links the centre, industry and universities to the future systems programme, while leaving procurement, staffing and governance details open until CAAS publishes them (CAAS, 22 July 2026).

Major systems and infrastructure

The announced systems include a NexGen Air Traffic Management System, an Integrated Digital Tower System, Info-Centric Air Traffic Management, and an Open Platform for Air Navigation Services. CAAS says NexGen ATMS is designed to support up to one million aircraft movements annually, process up to 4,000 concurrent aircraft positions in real time, and support up to 150 ATCO workstations; work is projected for completion in 2030. IDTS work is scheduled to start in August 2026, with first operationalisation in 2030 and full completion in the mid-2030s. The iATM is planned to start in 2027 and complete in 2030, while OPANS is projected for completion in 2028. These are planned capacities and milestones, not completed operational capability at announcement (CAAS, 22 July 2026).

Operational methods and interpretation

CAAS also described AI-enabled tools such as a Multi Sector Planner, Digital ATCO Assistant, automated read-back error detection and air-traffic-flow management. These tools are intended to augment trained controllers, reduce cognitive load and improve anticipation of traffic and weather constraints; they do not remove the need for licensed ATCOs or convert research prototypes into automatic safety approval. The Multi Sector Planner is planned for trials from 2027, and automated read-back error detection is expected to enter live trials later in 2026. Singapore's air-navigation modernisation should therefore be read as a staged capability programme involving people, technology, infrastructure and operating methods, with individual systems entering service on different schedules (CAAS, 22 July 2026).
