WP 4 En-Route Operations
WP 4 – En-Route Operations aims at providing the operational concept description for the En-Route Operations and perform its validation. The term En-Route includes both 'continental' and 'oceanic' applications. The results of these activities will contribute to the ATM Master Plan achievement by facilitating a pivotal change in the management of En-Route traffic, and by enabling a much more efficient management of traffic (including GA, military and UAV). This will be achieved through the best application of 4D Mission/Business Trajectories, supported by advanced procedures (employing concepts such as ASAS) and advanced safety nets.
The objectives of WP4 are to:
- Development, refine, and update the En-Route Operations concept, based upon the SESAR CONOPS and ensure consistency with other elements of the work programme;
- Define the En-Route Trajectory Management and Separations based upon performance based 4D navigation;
- Define the best application of the Mission/Business Trajectory;
- Define the appropriate ground and airborne safety nets;
- Establish case-based validation of the associated concepts, procedures and practices in accordance with recognised methodologies (e.g. E-OVCM).
In addition, a number of En-route related activities will be undertaken within WP 5 (TMA Operations), including Queue Management and Controller Working Position (CWP) definition. This reflects the importance placed on the effective interface between En-Route and TMA operations and therefore close cooperation between WP 4 and WP 5 will be ensured.
