The FAA deals with airlines, which figure out how to disseminate the information internally. > I'm honestly trying to understand how the notices get categorized, prioritized, "deduplicated" and distributed to everyone who needs to know without overwhelming pilots with unrelated stuff. Any international organization that has to abide by laws/regulations in different jurisdictions has to be competent at this. There will be bureaucrats and infrastructure to deal with the bureaucracy: country reps, lawyers, former pilots, endless mailing lists, etc.
