A METAR gives wind direction and speed relative to north. To understand its effect on a runway, turn it into a crosswind component and a headwind or tailwind component. This supports briefing; it does not override published limits or personal limits.
What you need
Compare wind direction and speed, including gusts, with runway orientation. The closer the angle is to 90 degrees, the closer the crosswind component is to the reported wind speed. When wind is aligned with the runway, the along-runway component prevails.
Aircraft and pilot margins
Check the AFM/POH. A demonstrated crosswind is not automatically a universal operating limit. Consider recency, experience, runway condition, width, turbulence and alternatives. FlightDesk gives a quick calculation, but official briefing and aircraft documentation remain decisive.
