It was gusting 40 to 70mph at yyz today, RJ9 has a max crosswind landing limit of 32mph... de-crabbed a plane that size on ice in heavy wind, interesting choice.
Cross-winds are bad. I was in Vancouver once flying to Victoria with a co-worker. We were supposed to take a helicopter but the winds were too bad so we caught a plane. Taking off, I'm pretty sure a wing just missed a ground and we looked at each other. Things were OK but it was probably the roughest flight I ever had.
