Information (weather, NOTAMs & overlays)

These tools live in the toolbar's Information section (formerly Weather). They are planning aids layered on top of the route — none of them change the route itself. The original IMS charts (SIGWX, wind/temp) open from the Charts section; the on-map overlays toggle here in Information.

All map-layer toggles read consistently: Show SIGMET, Show NOTAMs, Show wind effect, Show wind field, Show wind/temp, Show SIGWX.

SIGMET

Toggle Show SIGMET to overlay active SIGMET hazard areas for the Israel region (turbulence, icing, mountain wave, volcanic ash, dust, tropical cyclone, thunderstorm). A corner readout shows the count; click it to decode the raw text.

• Source: NOAA Aviation Weather Center, refreshed ~every 20 min by aviation-data.yml to the sigmet-data branch.

NOTAMs

Toggle Show NOTAMs to overlay active NOTAMs for the Israel FIR (LLLL).

• Map geometry — polygons, circles, route-closure lines, and a count badge at airfields for NOTAMs that carry no coordinates.
• Click / hover any area, line, or badge to open that NOTAM's text. Where a NOTAM overlaps another marker (VOR / airfield / nav-WP), it appears in the Choose point picker.
• Decoded view — the NOTAM text is decoded from the ICAO Q-code (subject + condition) with abbreviations expanded to plain English; a Raw toggle in the list modal shows the original source text.
• Timeline slider (0–72 h) under the toggle scrubs which NOTAMs are active at a future time; the panel also shows the feed's last-update time.
• NOTAM list — a full-text list button lives in the Charts section.
• CVFR route closures that name fixes (e.g. BTN NEGEV-HOVAV) are drawn as lines by resolving the fixes against the nav-waypoint / airfield / VOR data; reroute (DIVERTED VIA …) paths draw in a distinct colour.
• Border-buffer NOTAMs (e.g. "FM LEBANON BOUNDARY TO 8KM") carry no coordinates, so they're geocoded from an Israel border dataset (data/notam-borders.json) into a buffer polygon.
• Source: autorouter (Eurocontrol EAD), refreshed daily by notam.yml to the notam-data branch. Planning aid only — confirm against an official briefing.

Wind effect

Toggle Show wind effect to draw per-leg wind arrows, the route-wide wind readout, and the wind-triangle row in the leg inspector (wind correction angle, ground speed).

• Route-wide wind defaults to calm (000° / 0 kt); tunable (windDir / windSpeed). Fetch wind pulls forecast winds aloft per leg.

Wind field (live)

Toggle Show wind field for an animated winds-aloft field (~3000 ft) from a live Open-Meteo grid, with altitude / time / opacity controls.

Wind/temp (IMS PWX) overlay

Toggle Show wind/temp to lay the IMS PWX wind & temperature forecast over the map.

• Flight levels — all published levels: FL030, FL050, FL100, FL180, sorted low→high and defaulting to FL030.
• Valid time — auto-selected to the forecast closest to now (Zulu); the period is kept when you switch level.
• Opacity slider (default 60 %, ↻ reset). In dark mode a footer backdrop band keeps the chart's footer legible.
• Source: ims-charts.yml (hourly) → ims-data branch (pwx.json).
• Fine-tune alignment in Tuning Panel → Weather (IMS) (imsPwxLatOffset/LngOffset, imsPwxLatScale/LngScale, imsPwxRotationDeg).

The original full charts open from Charts → 🌬 Wind/temp charts (image viewer by level + valid time).

SIGWX on the map

Toggle Show SIGWX to overlay the IMS low-level significant-weather prog-chart on the map by valid time (also auto-set to nearest now).

• The chart is split into panels: the map frame is georeferenced over Israel (aligned to the LLHA, LLBS and LLIB airfields), the weather table is parked just east of Israel, and the title/valid-time header is shrunk to sit above the table.
• In dark mode the map panel's pale paper + terrain are knocked out so the base layer (CVFR, etc.) shows through — only the coloured hazard areas + labels overlay.
• Fine-tune everything in Tuning Panel → SIGWX overlay (panel + table offset / scale / rotation / opacity / white-knockout).

The original full chart opens from Charts → 🌐 SIGWX charts (image viewer by valid time).

Notes

• IMS / NOAA / autorouter / Eurocontrol data is advisory and may lag; always confirm against an official briefing.
• A scheduled monitor (charts-monitor.yml) checks each data feed's freshness and opens a tracking issue if a feed goes stale.
