Airport and TMA performance

This Essential Operational Change covers both changes to operations at Airports and TMA airspace that allow maintenance of operational capacity under limiting conditions and changes that allow increase in operational capacity during normal Operations. This includes enhancements to planning and execution of operations at/around the airport like traffic sequencing, reduced separation, reduced and more predictable runway occupancy time and enhanced management of taxiway throughput, for both arrivals and departures. This EOC addresses as well the needed coordination with TMA operations where aircraft sequencing towards the runway begins and even further with extended arrival management (E-AMAN) in en-route airspace. It also includes solutions that enhance the safety of operations and addresses as well the reduction of the environmental impact at or near airports. Enhanced navigation and accuracy in low visibility conditions on the airport surface needs to be made possible by the introduction of new airborne and CNS capabilities.
