Against the escalating impact of climate change, Changi Airport Group (CAG) recognises the importance of building climate resilience to ensure smooth round-the-clock operations. In collaboration with agencies and partners, CAG continues to examine the effects of increasing extreme weather patterns and develops mitigation strategies to fortify critical infrastructure across the airport. One such example is our efforts in future proofing the airport’s runways.
Preparing for higher rainfall intensity and rising sea levels
With the projected increase in rainfall intensity, CAG has grooved the asphaltic pavements of all three runways at Changi Airport. This reduces the danger of aquaplaning and runway excursions on wet surfaces during thunderstorm events.
To mitigate the potential impact of rising sea levels, CAG has also expanded the airfield drainage capacity to reduce flood risks. Ground-based aircraft navigation systems are further protected by flood barriers to ensure operational continuity.
In 2022, CAG’s Engineering and Development (E&D) Cluster partnered with the Aeronautical Telecommunications Engineering Division of the Civil Aviation Authority of Singapore (CAAS) to introduce a runway condition reporting system. The system capitalises on sensors to automatically alert air traffic controllers and pilots of any changes in environmental factors, such as runway water film depth. As one of the world’s first systems with such capability, this runway condition reporting system won the 2022 Minister for Transport Distinguished Innovation Award.
