I landed a Gulfstream Cheetah at Wellington's runway 16 in 45 knot winds gusting 55 knots from 240 degrees once. The crosswind limit on a Cheetah was 11 knots,
I'll bet your local aviation authority examiner wasn't watching! Since when have flight manual crosswind limits been able to be ignored if you de-crab?
I have heard that some Asian carriers do not teach de-crabbing. Probably because, as the videos show, the aircraft can handle it (provided the limits are not exceeded) and secondly, if you stuff it up and start drifting, you could end up anywhere. Given longhaul pilots don't do a lot of landings, "fly it on crooked" is probably not such a bad policy.
