How do you calculate the crosswind component on a runway?

Crosswind component is computed using trigonometry: Crosswind = Wind Velocity multiplied by the sine of the angle between the runway magnetic heading and the reported wind direction. Headwind component uses the cosine of the same angle.

What is the difference between headwind, tailwind, and crosswind?

Headwind blows directly against the aircraft landing direction and decreases ground speed. Tailwind blows from behind the aircraft, increasing ground speed and landing rollout distance. Crosswind blows perpendicular to the runway centerline and requires crab or sideslip corrections during approach and touchdown.

What are typical maximum demonstrated crosswind limits for commercial jets?

Most transport category jetliners, including the Airbus A320 and Boeing 737, feature maximum demonstrated crosswind limits between 33 and 38 knots on dry runways, which decrease to 15 to 25 knots on contaminated or wet runways.
