  2. Midhurst: Little difference in contours between existing and proposed. Some shift towards the south and slight extension of the 57 LAeq contour, but not signficant Blue – for 09R MIDonly - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Cyan– for 09R MIDproposed only - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Note: This is based on an average day of 09R Midhurst departures May-June 2012. Existing contour is based on radar data. Future contour assumes same fleet mix on new route.

  3. Southampton: Little difference in contours between existing and proposed. Some shift towards the south and slight extension of the 57 LAeq contour, but not significant. Smaller number of aircraft on this route, so contour smaller. Blue – for 09R MIDonly - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Cyan– for 09R MIDproposed only - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Note: This is based on an average day of 09R Southampton departures May-June 2012. Existing contour is based on radar data. Future contour assumes same fleet mix on new route.

  4. Compton/Bug: Due to concentration of aircraft (where currently there would be some dispersion) and new route placement the 57 LAEq contour extends further over some densely population areas where there may be a noticeable difference. Blue – for 09R MIDonly - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Cyan– for 09R MIDproposed only - existing 57-69 dB LAeq,16hr contours, 3 dB steps. Likely to be an improvement in this area due to route moving east and being more “programmed” Area may notice worsening on an easterly day Note: This is based on an average day of 09R Compton departures May-June 2012. Existing contour is based on radar data. Future contour assumes same fleet mix on new route.
