Missing approach in Garmin 530 database

Is this really true? If so, when did this policy come into effect? I'm
pretty sure that 10-15 years ago I encountered some procedure changes
(different missed approach, addition of "DME required") that remained as
published NOTAMs for many months.


You understand it correctly.

Mostly. Oh, sure, sometimes it will take an extra cycle or two to get
around to it. After all, NACO moves at the speed of government.

But not years. It's policy to incorporate changes to an approach into
the next revision of the plate. As with everything else, sometimes
this doesn't happen on time, but they do make an effort.

Simply not the case.
