What did the crew know?
Looking at Bomarc's post concerning the weather makes me wonder if the crew had this information:
"you have some points, however here is the wx, the first just prior to the landing and the second just after:
SPECI KCLE 181956Z 30016KT 1/4SM +SN BKN006 BKN015 OVC041 M07/M11 A3001 RMK AO2 P0000 $
SPECI KCLE 182017Z 33013G19KT 1/4SM +SN BKN003 BKN010 OVC015 M08/M11 A3003 RMK AO2 P0000 $ "
Did tower update them with the special, inluding the term "heavy snow?" What braking action report did tower give them? How old was it?
Decision-making is only as good as the accuracy of the information we receive and use to choose a course of action.
