⚠️ Exec policy constraints — The gateway runs in security=allowlist mode. To avoid approval prompts:

• Always use the full absolute path shown above — never ~ or {baseDir}.
• Never append shell redirections (2>/dev/null, >/tmp/out), pipes (| jq), or chaining (&& echo done). Redirections and chaining cause the allowlist to reject the command.
• Pass all options as flags to the script itself. Stderr is already handled internally.

How It Works

1. Pull active G-AIRMET IFR polygons (and optional SIGMET/AIRMET supplements).
2. Convert each area polygon into a bounding box and select a handful of airports in selected countries.
3. Query METAR via aviation_weather.sh, then report all checked airports with category and highlight MVFR, IFR, or LIFR.

Flags

• --hours <N>: look-back hours for weather-area scan (default 4)
• --source <gairmet|sigmet|both>: choose weather-area source (default both)
• --forecast-hour <N>: G-AIRMET forecast hour (default 0)
• --search-bbox <lat0,lon0,lat1,lon1>: region to scan (default 18,-170,72,-52)
• --countries <C1,C2,...>: airport country filter using ISO alpha-2 codes (default US)
• --max-areas <N>: max weather areas to evaluate (default 5)
• --airports-per-area <N>: airport sample size for each area (default 5)
• --metar-hours <N>: METAR look-back hours (default 2)
• --json: emit structured JSON output
• --debug: include full METAR JSON records for checked airports
• --debug-airport <ICAO>: only print debug METAR JSON for one airport code

Notes

• Default bbox includes AK/HI and excludes Europe/Asia.
• G-AIRMET coverage is CONUS-focused; use --source both to blend with SIGMET/AIRMET coverage.
• Airports are filtered by --countries (default US) in station metadata.
• Flight category (VFR/MVFR/IFR/LIFR) comes directly from METAR fltCat in AviationWeather API JSON.
• If fltCat is missing, category is derived from METAR visibility and ceiling fallback logic.
