The following article was in the February 8th, 2004 Cargo Facts European Perspective section:
“Noisy 747-200s? There is a lot of loose talk going on about the future viability of the 747-200 freighter. Massimo Panagia, managing director of Alitalia Cargo, said that the type was facing restrictions at “most” European airports. Other carriers are part-justifying their investment in new 747-400 freighters on the same basis. Now, it is true that many 747-200s only meet chapter 3 standards thanks to flap and power restrictions (JT9D-powered aircraft). But the is, no European airport has yet tried to ban outright, aircraft like the 747-200 that do not meet “Chapter 3 minus 5dB”. Nor can they quickly do so, according to the “balanced approach” that was agreed between the EU and the U.S. during acrimonious row over Hushkits. Yes, Paris CDG, Cologne and a few others have imposed night-time restrictions. But any airport seeking a total ban must consult first, and then phase such aircraft out over a five year period. None have yet embarked on this course. As for the much-discussed “Chapter 4”, its application to existing (as opposed to new-build) aircraft is yet to be defined, let alone approved.”
