In the scenario described at the top of this article, we’re trying to get back to home plate in 800 overcast and two miles, somewhere in the U.S. It’s a good idea to get an IFR clearance to deal with that low of a ceiling. But what if the ceiling was 5000 overcast, or unlimited, with the same two miles of visibility? You’d still need a clearance to get home, but it doesn’t have to be an IFR.
