If both visibility (slant range vis.) and vertical vis. is reported via ATIS, METAR: Which is controlling when determining if the visibility meets approach plate minimums?
I assume slant range (what the pilot should see from the cockpit) is controlling for the vis. portion of the approach plate and vertical vis. more for the ceiling requirement mins. for the approach plate since vertical vis. is reported when there is not a measurable ceiling of which is fog.
Thanks for the feedback.
