At my airline, the crosswind limitations for the CR7 are as follows:
For takeoff:
28kts if braking action is good or better;
15kts if braking action is fair;
10kts if braking action is poor.
For landing:
30kts
15kts
10kts with the same braking action stipulations.
These are steady-states speeds, not gusts, so if I'm landing on Runway 36 and the wind is reporting 270/29G45, I'm still legal.
