# What degree is crosswind? [closed]

I know that there are three type of wind, headwind, tailwind and crosswind. What degree of wind direction can distinguish it? 30 or 45 degree?

• So you want to know how many degrees of crosswind component qualifies a wind to officially be called a "crosswind"? You won't find that any where in the FARs or AIM, so I guess it's not a real thing. – quiet flyer Aug 30 '20 at 13:26
• I'm not sure we can speak in degrees. I think we usually divide the wind in 2 components (one on the axis of whatever you consider --route, runway,...-- and another perpendicular) and speak of cross-wind component. crosswind would be if the sideway component is above a threshold. – Manu H Aug 30 '20 at 13:51
• Ah I just thought of the real answer-- if there's enough sideways wind component that we should land with a sideslip rather than a forward slip, then it counts as a crosswind. – quiet flyer Aug 30 '20 at 16:00
• We should probably look at wind as only having two types, crosswind and wind in our direction of travel. Headwind and tailwind are the same type. One is the inverse of the other. Or, you can say that one is the negative and one is the positive of the same type. Otherwise, why wouldn’t you say that there are four types of wind: headwind, tailwind, left crosswind, and right crosswind? And, breaking it down further into quartering winds would confuse matters even more by adding four more types. It is more correct to say that there is only one type broken into two components for our practical use. – Dean F. Aug 30 '20 at 16:54
