Airbubba..Just repeating what a Birmingham controller wrote on a union blog....
Thanks for sharing it, most of what I know about the mishap outside of the NTSB briefings is similarly anecdotal.
Possibly not having any Rwy 18 NavDB stuff would definitely explain why they opted for the LOC (manually tuned I assume) and not the RNAV.
Perhaps not a player with UPS but some of the A306's I flew years ago had FMS's with very limited memory and internationally some procedures would not be in the database or, even worse, waypoints and constraints would be missing. I flew with Sperry, Smiths and some other kind of FMS, I can't remember. I think UPS only uses the A306's domestically these days so maybe this isn't a problem anymore.
