I always thought that wind coorection are taken from the wind which is reported at 20-30 feet above R/w so 2000 feet logic does not make sence to me (correct me if i am wrong)and I agree that boeing does recommand wind correction but airbuss restrict you to a correction of max 20 knots and if you have configuration problem which requires you to put in 20 knots then they dont want you to put any correction.How can we ecplain that?
