The Time-Based Separation (TBS) concept defines a set of wake separation rules in terms of time rather than distance to improve runway throughput resilience to strong headwind conditions. The controllers need tool support to translate the required time separation / spacing into the equivalent distance separation / spacing for the prevailing headwind conditions to enable visualisation of the required time separation / spacing on the applicable Approach and Tower Controller Working Positions (CWP).
The EUROCONTROL Specification for Time Based Separation support tool for Final Approach defines a set of performance requirements for a TBS support tool, which complies with Commission Implementing Regulation (EU) No 716/2014 and supports the deployment of ATM Functionality (AF) 2: “Airport Integration and Throughput”, sub-functionality “Time-Based Separation for Final Approach” as well as Operational Improvement (OI) Step AO-0303 ‘’TBS for Final Approach’’ from the ATM Master Plan and other wake turbulence OI Steps such as AO-0306 “Wake turbulence separations based on static aircraft characteristics”.
The draft EUROCONTROL Specification for Time Based Separation for Final Approach was submitted to a formal written consultation from 15 April 2016 to 8 July 2016 using the EUROCONTROL Standards Development Process mechanism.
