The most important is being able to see the runway you are landing on. With those weather conditions the pilot might have had a lot of difficulty with that.
Yeah the spinny-thingy-up-front planes I flew REQUIRED a view of the runway. I simply could not fly/ would not fly when the weather was close to minimums at the destination.
I was OK up in or above the soup (IFR) but NOT low ceilings and fog on approach. Hated that, arguably wasn’t 100% safe as a pilot, so I didn’t take off.
