Changi Control Tower to undergo upgrading as part of S$4 billion air navigation overhaul

A digital assistant is also being developed to help air traffic control officers anticipate emerging traffic and weather situations, provide recommendations on how aircraft should be sequenced and spaced, and manage disruptions.

Later this year, CAAS will begin live trials of an automated tool that detects read-back errors between pilots and air traffic control officers.

“This will help reduce safety occurrences like runway incursions and loss of separations,” the authority said.

CAAS is also using technology to better predict the impact of weather on flight movements so controllers can better anticipate bottlenecks and constraints, intervene early and reduce diversions to other airports.

IMPROVING REGIONAL TRAFFIC FLOWS

CAAS is developing an AI-enabled air traffic flow management tool to anticipate and analyse gaps between demand and capacity, as well as propose recommendations that air navigation service providers can adopt.

Since September 2025, CAAS, the Air Traffic Management Bureau of the Civil Aviation Administration of China and and the Hong Kong Civil Aviation Department have held daily calls to share information and coordinate air traffic flows.

Air navigation authorities from South Korea, Thailand and Vietnam have since joined these calls.

“As a global air hub, we are committed to serving all airspace users and to deliver for them an even smoother, more seamless and safer travel experience,” CAAS’ Mr Han.

“We plan ahead. We invest, partner and leverage technology to ensure that we have the capacity and capabilities we need to meet rising demand and benefit from aviation’s growth.”
