Flight Rules column for airports


Would it be possible to improve the accuracy of the flight rules column?
The FAA defines the conditions as follows:

VFR= >3000’ ceiling and >5 miles visibility
MVFR= 1000’-<3000’ ceiling and 3-5 miles visibility
IFR= 500-1000’ ceiling and 1 to<3 miles visibility
LIFR= <500’ ceiling and < 1 mile visibility

I think this would give a clearer picture of what’s happening at the airport in question. Otherwise, I think this site is great!


That should be what we’re using, where do you see otherwise?


I saw it on some Wx reports for ORD back before Christmas, where several instances of 4000-7000’ ceilings with 2 miles vis. were classified as LIFR.
