In recent years, there have been a number of initiatives to review and update the wake turbulence categories defined by ICAO and the corresponding state variations.

IFATCA Policy is:

Any aircraft wake turbulence recategorisation shall:

  • Conduct appropriate safety assessments, including a thorough understanding of the human factor element.
  • Design clear procedures for the application of the new wake turbulence categories.
  • Provide adequate tools to support the controller when applying those procedures.
  • Incorporate contingency procedures for cases where support tools are unavailable and/or the new wake turbulence categories cannot be applied.
  • Ensure that the new system does not have a negative effect on the efficiency of the overall ATM system.

When the prescribed separation is applied, ATCOs shall not be held responsible for wake vortex encounters and related accidents/incidents.
