I-MATE
Real-time AI decision-support system for aircraft pushback scheduling at Singapore Changi Airport.
I-MATE (Intelligent Metering of Aircraft for Taxi-out Efficiency) is a real-time decision-support system that recommends intelligent aircraft pushback times to minimise airport surface congestion. It was built and validated at the Air Traffic Management Research Institute, NTU Singapore, for deployment at Singapore Changi Airport.
Operational impact:
- 25.6% reduction in average taxi delays
- $18 million estimated annual fuel savings
- 22% fuel consumption reduction
- 7/8 usability rating from professional air traffic controllers
- Progressively adopted into live operations
- Technology disclosure filed in 2022
What this demonstrates:
- Real-time decision-support systems
- Mathematical optimisation under uncertainty
- Large-scale data analysis (62M+ trajectory records)
- Stakeholder engagement with CAAS and Changi Airport Group
- Human-AI collaboration in safety-critical operations
