Wind Benefit
Wind benefit is not calculated by halving the wind intensity. Wind benefit is the actual weight increase produced by the presence of the wind, therefore any discount is the weight discount and not the wind.
Wind benefit is mandatory factored to 50% only for Cat A certification, for all the other performance data, including the mandatory performance, data can be presented unfactored, i.e. with 100% benefit. It is upon operator responsibility to use the correct factorized weight based on the operational rules where he is operating.
