According to the Flight Test Guide there are two possibilities on how to note crosswinds in the Aircraft Flight Manual AFM.1 If the demonstrated crosswind is not considered to be a limiting value for aircraft handling characteristics, this demonstrated value can be placed as information in the AFM. Higher crosswinds are then allowed when the applicable operational requirements and the airline specification allow it. For instance, the AFM of the B737-400 states the following on crosswind “The maximum demonstrated crosswind component for takeoff and landing is 35 knots reported wind at 10 meter height. This component is not considered to be limiting on a dry runway with all engines operating”.
