VLD.03 W2 Improving runway throughput in one airport


The VLD aims at demonstrating the following candidate SESAR Solutions that improve runway throughput while keeping safety levels:

  • Arrival concept Static-Pairwise (S-PWS or PWS-A) provides a more precise definition of the minimum safe wake separation required for a pair of ICAO aircraft types through an optimisation of the ICAO wake turbulence separation classes;
  • Wake Turbulence Separations (for Departures) based on Static Aircraft Characteristics aims at optimizing the ICAO wake turbulence separation classes by use of longitudinal wake turbulence static pair-wise separation (S-PWS) minima on departures for the initial common departure path from the runway, applicable in all operating conditions;
  • Weather-dependent reductions of separation may also be demonstrated;
  • Optimised Runway Delivery (ORD) for arrival and departures that have been also developed in the solution shall be used. These tools make use of Target Distance Indicators (TDIs) to enable consistent and efficient delivery of the required separation or spacing between arrival pairs on final approach up to the runway landing threshold;
  • Wake decay enhancing concepts a technical design of the so-called plate lines shall be elaborated that is compatible with airport structural requirements (e.g. stability, frangibility) and approval of authorities for the installation of the plate line shall be obtained;
  • Reduction of radar separation to 2NM for in-trail pairs on final approach Solution #02-03 (researched in Wave 1) refers to the concept of Minimum Pair Separation Based on Required Surveillance Performance (RSP) in support of a reduction of the in-trail Minimum Radar Separation from 2.5 NM to 2 NM on final approach at Large and Medium Airports and TMA High Complexity and TMA Medium Complexity sub-operational environments so as to provide a direct positive impact on runway throughput during periods of capacity constrained operations;
  • Integrated AMAN-DMAN SESAR considers a number of concepts that aim at optimizing runway operations by providing dynamic assistance to controllers and supervisors in TWR and TMA. Their objectives are to increase runway throughput through the optimisation of arrival/departure spacing. The improvements include the use of a Runway Manager (RMAN) to optimise the planning of the runway use, and the sequence-based coupling of AMAN and DMAN including a sequence update a few minutes before touchdown and the use of TDIs between arrivals to support ATCOs to create the right gap between arrivals. This VLD will demonstrate the application of these concepts in order to optimise the use of the runway capacity for single or multiple runway airports;
  • The VLD may include activities to complete the TRL-6 maturity for candidate solutions 83 ‘Surveillance Performance Monitoring’ and 84 ‘New use and evolution of Cooperative and Non-Cooperative Surveillance’.

At capacity constrained airports traffic demand for runway operations exceeds the runway capacity. With the growth in air traffic there is an increasing number of airports that are becoming capacity constrained for significant periods of each day.

  • Safety: Maintain or increase runway, taxiway and apron safety levels, increase situational awareness. ATC Workload maintained or reduced;
  • Airport and Airspace TMA Capacity - Increase runway and airspace throughput (e.g. reducing runway occupancy time, or landing and departure wake turbulence separation) and resilience;
