SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Pilots planning UK general aviation flights must manually gather METARs, TAFs, the Met Office F215 chart, forecast models, and turbulence data from scattered sources, then interpret coded aviation weather text themselves. This Skill orchestrates focused sub-skills to fetch each data category and synthesizes everything into a single narrative briefing. ## Core Features & Use Cases - Multi-source data orchestration: Delegates to sub-skills for airfield finding, METAR/TAF fetching and decoding, F215 chart retrieval, Open-Meteo hourly forecasts, and turbulence analysis, then synthesizes the results. - Structured narrative briefing: Produces a fixed-format briefing covering synoptic situation, airfield conditions, visibility and cloud, wind and turbulence, precipitation, freezing level, and pressure, with strict meteorological accuracy rules. - Optional email delivery: Sends the assembled briefing via Gmail SMTP when explicitly requested, attaching the F215 PDF. - Use Case: Ask for a weather briefing for a flight from Andrewsfield (EGSL) to another UK airfield, and receive a complete narrative briefing with raw METAR/TAF appendix, plain-English decodes, and source links. ## Quick Start Ask for a GA weather briefing for a UK airfield or route, for example: give me a weather briefing for a flight from EGSL to EGSU this afternoon.

FAQPage Schema
How do I get a UK aviation weather briefing from METAR and TAF data?▼

Request a briefing with one or two UK ICAO codes and the skill fetches METARs, TAFs, the F215 chart, and forecast model data via sub-skills, then writes a structured narrative briefing. It covers wind, visibility, cloud, freezing level, and turbulence with raw reports appended.

What weather data sources does a GA flight briefing need?▼

This briefing combines METAR/TAF reports, the Met Office F215 low-level area forecast chart via MAVIS, Open-Meteo hourly model forecasts, and a turbulence analysis. It explicitly does not include NOTAMs, SIGMETs, AIRMETs, or PIREPs, which pilots must check separately.

Does the F215 chart fetcher require Met Office credentials?▼

Yes, fetching the F215 chart requires a Met Office account with MAVIS access configured in the f215-chart-fetcher sub-skill's own .env file. If credentials are missing or the MAVIS login fails, the briefing continues without the chart and notes the gap plainly.

Can I email the generated weather briefing via Gmail?▼

Yes, but only when explicitly requested. The skill writes the briefing to a file and calls the gmail-sender sub-skill with a Gmail App Password, optionally attaching the F215 PDF. Email sending is never automatic.

What are the limitations of this aviation weather briefing?▼

The briefing excludes NOTAMs, SIGMETs, AIRMETs, and PIREPs, and cannot compute crosswind components because no verified runway heading data is available. Open-Meteo forecast data is uncertified model output, always subordinated to official TAF, METAR, and F215 sources.
