Thank you both for your reply.I gather from your posts that the crosswind limitation is solely a consideration in maintaining directional control on the runway during a landing or a rejected takeoff with the aid of differential braking.
Are the airborne handling characteristics considered in the equation (so to speak) if for instance a critical engine is lost with maximum xwind adding to the rudder correction required.
If I remember correctly the xwind limit on the light turbo-prop Embraer 110 was TKOFF 18kts and LDG 25kts.
