Chapter 4/Stage 4 Outlook

[747FOCAL]

has anyone heard what Boeing and Airbus will be charging their customers for new AFM pages that state their aircraft is Stage 4/Chapter 4 compliant? Just doing some fleet planning and the input would be most helpful. You call both of them and you get the standard, I dunno but I get back to you in 6 months answer.

Nope, but why do we need a certificate? We have the actual noise levels in the AFM, generally airports dont ask us for the Certification level, but the noise level.
