Crosswind FAQs
Common questions about crosswind component.
How is crosswind calculated?
Crosswind = wind speed × sin(wind direction − runway heading). Headwind uses cosine.
Should I use magnetic or true direction?
Use a consistent reference — typically magnetic for runway numbers and ATIS/METAR wind in the US.
