Vortex pruning
You better believe it. Whilst living in Cairns at the near northern suburb of Holloways Beach, and just to the left of the ILS track, on numerous times I heard and saw visible effects of vortex action. Surprisingly, the main a/c type to cause the most action was the BAE 146. Several seconds after passage of the a/c, you could hear the vortex descending ,and numerous times, it whipped the top leaves from some of the trees in the yard. Hate to have been a poor sucker in a C150 cutting in on a tight left base at that time !!!
