CM-0607 — Separation Management in En-Route using RBTs with 2D RNP Specifications

The Reference Business Trajectory (RBT) is a 'precision trajectory' in that it may include required navigational performances associated to the Pre-defined or User-preferred routes of RBT e.g. 2D RNP specifications. The RBT may be revised using additional or amended lateral routes/waypoints and/or level to ensure separation in execution phase; ATC clearances are included as part of the RBT Revision process. User-preferred Trajectories/Revisions may include non-published waypoints that are computed by Ground tools (ideally using information from the airborne system) and defined in lat/long or bearing/range. Vertical constraint and longitudinal separation is provided by ATC to complement the 2D route (using information from the airborne system). This may be achieved through surveillance based separation and/or the dynamic application of constraints. New support tools and procedures and working methods have to be put in place.
