Have your say on plume rise assessments

Date published: 5 May 2022

We are consulting on a draft advisory circular (AC) that will provide guidance and information on plume rise assessments.
Have your say

The purpose of draft AC 139.E-02 v1.0 is to:

  • provide a standard method of determining the probability of an aircraft experiencing turbulence when flying in the vicinity of a facility emitting a vertical exhaust plume
  • ensure that the impact of plumes can be assessed in a consistent and reliable way
  • provide guidance to stakeholders involved in the approval, design and operation of facilities with vertical exhaust plumes to assess the potential hazard from a plume to aircraft operations
  • provide guidance to stakeholders on the plume rise assessment process.

Submit your feedback on the Consultation Hub before 20 May 2022.
