In another life I used to fly a medium category helicopter.
At the start of my career - as a lowly PPL I would never have thought a chopper would generate that amount of wake turb.
I used give lighties following me in the circuit a heads up.
Better I take up 2 seconds of CTAF time rather than have to start up again and medivac some punters out of their busted up sportstar or Jabiru....Three words - much more efficient.
