Crosswind Component

The Crosswind Component is the vector component of wind that blows perpendicular to the runway centerline. It is one of the most critical factors in takeoff and landing, requiring the pilot to apply appropriate control inputs to maintain directional control.

• Calculated from wind speed and the angle between wind direction and runway heading
• Formula: Crosswind = Wind Speed × sin(Wind Angle)
• Each aircraft type has a maximum demonstrated crosswind component (e.g., B737: 33 kt)
• Exceeding limits may be prohibited by company operations manuals
• Strong crosswinds may require crab or side-slip landing techniques
• Gusty crosswinds are more hazardous than steady crosswinds
