Use this before comparing a wind report with aircraft or runway operating limits, or when a performance calculation needs the along-runway component rather than total wind speed.

The calculator subtracts runway heading from the direction the wind comes from, then applies cosine for the headwind component and sine for the crosswind component. A negative headwind is a tailwind; the crosswind sign preserves side.^{[1, 2]}

Headings must share the same magnetic or true reference. This geometric decomposition does not account for gust policy, runway contamination, terrain, wind shear, or aircraft-specific limitations.

Choose the neighboring tool according to whether you need the inverse conversion, a narrower calculation, or the next step in the workflow.

• Headwind Component Calculator

  Use when only the along-runway component is needed.

• Crosswind Component Calculator

  Use when only crosswind magnitude is needed.

• Total Wind Component Calculator

  Recombine known orthogonal components into wind magnitude.

• Wind Decomposition Calculator

  Decompose a wind relative to the course into headwind and crosswind components using headwindComponentKt = windSpeedKt * cos(angle) and crosswindComponentKt = windSpeedKt * sin(angle).

• Quartering Wind Component

  Resolve reported wind-from direction and speed against a runway heading. Positive headwind means wind from ahead; a negative value is a tailwind. Signed crosswind is relative to the heading and should be interpreted with local runway convention.

• Crosswind Takeoff Check

  Resolve wind speed into an absolute crosswind component relative to runway heading and compare it with a user-supplied aircraft or pilot limit. This checks only the wind component, not runway condition or takeoff performance.
