All graphics confirm. Good digging Anons…
Weather in Hanoi at Noi Bai (VVNB) - foggy for last 4.5 hrs. See graphic. "LIFR"
Low Instrument Flight Rules (LIFR): Ceilings are less than 500 feet and/or visibility is less than 1 mile.
LIFR = <500′ and/or <1 mile
In other words, even experienced IFR pilots may have a hard time. With these conditions, they will break out just above the standard minimums for an ILS approach (200-1/2)
