How this works: everything runs locally in your browser — no file is uploaded anywhere. The parser groups content the same way the legacy briefing does: a bold "COMPANY NOTAMS" label under an airport becomes that airport's Company section (as in Mission+); freestanding "GENERAL" content becomes company-wide NOTAMs; any block headed by "... FIR (XXXX)" alone (no paired airport) becomes an Airspace section. Sequence numbers before the "/" are arbitrary for sim use — only the year after the "/" is updated to match your chosen date. Apply Simulator Date re-dates every NOTAM so it reads as genuinely current on that day: each NOTAM keeps its own original duration (a 2-day runway closure stays a 2-day closure) but is repositioned to start on or just before your chosen date, so the briefing looks live rather than showing NOTAMs that have already expired. Standing/UFN items and Company NOTAMs remain open-ended. Add Custom NOTAM lets you insert your own entries (e.g. for a specific training scenario) formatted exactly like the rest of the briefing — they participate in Apply Simulator Date the same as parsed ones. This is a best-effort parser: scan the preview below and use the small "Remove" control on any card that parsed incorrectly before downloading. This tool does not attempt to auto-classify airports as Departure/Destination/Alternate — all airport and FIR blocks are shown in the order they appeared in the source document.
