Approach to Capacity Building • Determine the current capacity • Identify measures to be implemented to enhance
capacity • Develop action plan to implement measures
• Take phased approach to increase scheduling rate • Formulate and design enablers • Increase ATCO manpower and enhance training • Expose ATCOs to an environment of high intensity
operations • Measure performance to determine effectiveness

• Route restructuring • Reduction in Horizontal
Separation
• No Pre-departure Clearance
• Streamlining departure clearance
• Reconfiguration of Approach Sector
• Continuous Descent Operations
• Gate-hold Procedures • Pushback procedures • 1-minute departure
separation

Runway Capacity Enhancement • Optimising pushback procedures to enhance capacity
through flexibility • Mixed-mode runway operations to maximize both
Runways utilization • Gate-hold procedures, pushback time varied to reduce
waiting time and congestion on the taxiway, as well as to reduce fuel burn.
• Enhancements to ATC sequencing to minimize overall separation intervals: Move away from first-come-first-served basis

Maximising Runway Occupancy Time • Fostering awareness among stakeholders on need to
improve performance • Publish ROT recommendations in AIP • Set performance target for major airlines according to
fleet mix

Conclusion
• Taking a phased approach in growing capacity • Identify measures that can support capacity
enhancement • Plan and prepare implementation, taking into
considerations procedures, resources, training, etc. • Measure effectiveness of initiatives using metrics such
as ROT performance, delay, workload and feedback from users
• Collaboration with stakeholders to work together on capacity building journey.
