ATS 3.36 RECATEGORIZATION OF AIRCRAFT FOR WAKE TURBULENCE

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. The main aim has been to either reduce the wake turbulence separations or make them dependent on the wind conditions in order to increase the capacity, efficiency and resilience of airport operations.


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.

IFATCA Policy is:

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