WAKESEP – Wake Vortex Separation Reductions

The aim of the WakeSep project is to support the development of new operational concepts employing reduced wake vortex separations. The project provides a structure within which specific concepts can be developed and validated.


WakeSep is a EUROCONTROL project that co-ordinates a number of on-going activities in the domain of WV (Wake Vortex) research. The project aims to co-ordinate the completion of the required research, the development of operational concepts, and the definition of appropriate validation methods.


The objectives of the WakeSep project are:
  • H1) to support research and development of new concepts employing conditional reduction of WV separation standards, through the elaboration of validation methods, the development of operational concepts, and the provision of communication tools and forums; and
  • H2) to identify European airports where WV separation reduction would bring significant benefit and to work with these airports to facilitate implementation.


WakeSep is a support project in that its primary outputs are used by other projects looking at more specific aspects of WV separations. Thus, WakeSep looks at the development of tools and methods that will be of value to projects looking at specific WV mitigation concepts. For example, WakeSep provides support to the TBS (Time-Based Separations) project and the CREDOS (Crosswind Reduced Departure Separations) project both of which are looking at specific mid-term concepts.

In addition to tools and methods, WakeSep also aims to provide communication support, particularly concerning stakeholder communication. Two important elements of this are the continuation of the European thematic network on WV research and the European WV Concepts Teams.

Expected results

The expected results are:
  • ER1) A requirements specification for ground-based WV detection systems in terms of performance, reliability, and availability;
  • ER2) A requirements specification for meteorological forecasting systems for operational WV mitigation procedures;
  • ER3) A listing of European airports where the greatest benefit would be attained from the implementation of WV mitigation procedures;
  • ER4) A definition of a safety methodology that is acceptable to ICAO and national regulators in the production of safety cases (including a risk assessment methodology for calculating the required safe separation distances under different meteorological conditions);
  • ER5) A feasibility study of the use of CSPR operations at suitable European airports;
  • ER6) The development of specific WV operational concepts at the target airports through a process of broad discussion with local experts and stakeholders;
  • ER7) A project proposal for the further development of an operational WV prediction and monitoring system as specified by the ATC-Wake project in readiness for the 7th FP calls;
  • ER8) A high level of information exchange between researchers within Europe and between Europe and the USA, through the continuation of the WakeNet structures and other ad hoc exchanges; and
  • ER9) The involvement of the ATC- and pilot- community stakeholders in WV research and implementation activities and results.
