Definition#
A crosswind is the component of wind that blows perpendicular to the runway heading or aircraft ground track. It is calculated from the reported wind direction and speed relative to the runway in use.
Why It Matters Operationally#
Crosswinds require crab angles on approach and wing-low or decrab techniques during landing. Each aircraft type has a maximum demonstrated crosswind component. Strong crosswinds can close runways or require runway changes.
