Marlboro,
This is certainly interesting, especially if you havent changed anything on DEP.
Do you know if other airlines have the same experience?
In monitoring the wake turbulence, I have noted that the marine and inversion layers have an effect on noise transfer. The layers will reflect and deflect noise as well as the wake vortex.
If the violations are happening mostly at dusk, this may be from the marine/invection layer rises this will cause noise to bounce off and down, amplifying the noise in certain directions.
Prevailing winds due to invection will also direct/concentrate noise to areas outside of the normal flight noise contours...
Would be interesting to see the specifics, as currently, we are looking at methods to purposely direct noise with winds and invection/inversion layering.
Parabellum, you still in VIC area?
