I always assume you read (and understand) the POH, or better Owner's Manual as we may talk mostly on old GA aircraft. Crosswind operational limits on vendor manual level are a rare case and many will never seem them in their whole life. Crosswind
demonstrated limits in handbooks are, citation 'with average pilot technique direct crosswinds handled with safety' - so, average pilot (which is by the definition a rather low time pilot on barely minimum annual hours) and still with safety margin. Btw, final decision is by PIC not book - no pilot will suicidal crash dive into the canyon because the crosswind component of the airfield is reported a mile high. Operational limits set internally by flying clubs, insurances, airports (yes, there are airfields closing when crosswinds exceed airport certification limits, usually by orographic reason, so you have to declare emergency to land in such instance) or AOC companies are a totally different story.
