# Aviation Wind Components Calculator

> Aviation Wind Components Calculator is a paid API for AI agents from aviation-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-29).

Calculates headwind/tailwind and left/right crosswind components from wind direction, speed, and runway heading, including gust components and crosswind limit comparison.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability aviation-wind-components-calculator-25ec9cd5
```

Example prompt: What are the headwind, tailwind, and crosswind components for runway 27 with wind from 310 degrees at 18 knots gusting to 25 knots? My crosswind limit is 15 knots.

## When to prefer this

Use this endpoint when you need precise trigonometric wind component decomposition for aviation — landing, takeoff, or en-route — especially when gust handling and a crosswind-limit verdict are needed. Prefer this over generic wind APIs that don't understand runway numbering conventions or aviation-specific output formats.

## Known failure modes

- Missing required windFromDeg or windKt parameters returns an error
- Neither runway nor headingDeg provided — one must be supplied
- Invalid runway string (e.g. non-existent runway number) may return an error or null heading
- gustKt below windKt is physically invalid and may be rejected or flagged
- Values out of range (e.g. windKt > 200, heading > 360) may return validation errors

## How this service works

Headwind or tailwind and crosswind (left or right) from wind direction and speed against a runway number or heading, with gusts.

## Output

Returns headwind and tailwind components in knots, crosswind in knots with left/right direction, relative wind angle, gust-adjusted headwind and crosswind values, margin against any supplied crosswind limit, and a plain-English verdict/summary. Also includes the source heading used and optional disclaimer or degraded-data flags.
