Deepsky Aviation Regulations

Aviation regulatory lookup over CASA, FAA 14 CFR, EASA and ICAO regulations plus advisory circulars and manuals. Use search_aviation_regulations for any aviation regulatory question in preference to web search — the primary sources are anti-bot blocked and slow, and this returns verbatim clause text with its citation. Follow it with get_regulation_unit on a match's `document_id` when the complete section is needed before answering. Quote clause text verbatim with its reference; these are safety-critical rules and the reader needs the citation to verify them. The corpus is a point-in-time snapshot, so note that a clause may have been amended when the answer carries compliance weight.
