Airbus Chapter 4

[747FOCAL]

Has Airbus converted any of their planes to Chapter 4 noise regs yet? Just curious as it makes no difference.

Last time I was briefed at TLS they said all current production types/engine combinations meet Stage 4/Chapter 4 and the new emissions regs. - believe the CF6 and PW4000 powered A310's and A300-600's also comply. Early A300's will struggle but may achieve the baseline with performance trade offs.
