If memory serves, 52 kts was a JAR limitation. (Tailwind on the rudder?)
Cannot recall any manufacture's max figure, although a figure of 75 kts was banded about, 10 years ago.
I have tried landings in 'serious' crosswinds in the FTEJerez 737-800 sim. Fun and a great confidence boosting exercise for the more competent student. The "Q" seats are very realistic.
Blowy down here last night in Sunny Troon.
