Instructions excerpt

Aviation weather from the NWS Aviation Weather Center (aviationweather.gov). Keyless, no API key required. Covers METARs, TAFs, PIREPs, and domestic SIGMETs. AIRMETs are not served — aviation_get_advisories rejects a request for one rather than answering it with SIGMETs. IMPORTANT: This data is for informational purposes only. Flight operations in IMC or controlled airspace require an official preflight briefing from an authorized source (e.g., 1800wxbrief.com). Station IDs are ICAO format (4 letters, e.g. KSEA, KJFK). Use aviation_find_stations to resolve unknown IDs or discover stations in a region.
