This FAA website indicates that the "International Flight Information Manual (IFIM)" is a downloadable publication of the FAA.
I've never heard of this manual before today, and would like to download a copy of it. However, clicking the provided link takes me to this page, which doesn't seem to mention the IFIM at all.
Have I missed spotting it? Is it available for download from somewhere else? Or is this a mistake or outdated information?
