CS 25.237Wind velocities
(a)The following applies:
(1)A 90° cross component of wind velocity, demonstrated to be safe for take-off and landing, must be established for dry runways and must be at least 37 km/h (20 kt) or 0·2 VSR0, whichever is greater, except that it need not exceed 46 km/h (25 kt).
(2)The crosswind component for takeoff established without ice accretions is valid in icing conditions.
(3)The landing crosswind component must be established for:
(i)Non-icing conditions, and
(ii)Icing conditions with the most critical of the landing ice accretion(s) defined in appendix C and O, as applicable, in accordance with CS 25.21(g).
