Jumpseater,

When do you think arrivals will start getting penalized?

Something for anybody that cares....... I have seen plenty of data from tests that shows people would rather have a louder noise for a shorter time than a quieter noise for longer duration. The people generally would stomach a 3-4 dB increase in noise for the shorter duration before switching to liking the quieter levels. If you do not understand the dB scale 3-4 dB is substantial. Now having said that I have seen A380 projected approach speeds.........she will be moving roughly 20-25 kts slower than a 747 on approach.
