Crosswind Component
Wind direction + speed + runway → headwind/tailwind and crosswind components. Same math as the E6B, fast enough to redo at the hold-short line.
Inputs
From the METAR/ATIS. Direction wind is FROM (0-360).
Enter a runway number ("27") OR a full heading ("273"). We figure it out.
Verdict
—
Enter wind direction, speed, and runway

About this calculator
Pure trigonometry. Headwind = windSpeed × cos(angle). Crosswind = |windSpeed × sin(angle)|. Same formula your E6B uses. Wind angle is normalized across the 0/360° wrap so a 350° wind on runway 010° reads as 20° from the left — not 340° from the right.
Risk band defaults to 15 kt — the demonstrated crosswind for a stock C172. Your aircraft may differ. Always check your POH limitations.
