CxAVOK

Aviation weather at a glance

Free · Designed for iPad. Not verified for macOS.

See the weather across your whole region in one look — METAR and TAF drawn as a heatmap, with a basemap that works with no signal. CxAVOK draws METAR observations and TAF forecasts as a heatmap over the map, so the weather across a whole region reads at a glance instead of one station at a time. CAVOK is the abbreviation for Ceiling And Visibility OK: no significant weather, ceiling above 5,000 ft, visibility 10 km or more. In short, great weather for flying. REGIONAL HEATMAP Flight category, ceiling, visibility, wind, or temperature/dew-point spread, interpolated across every reporting station inside a region you centre and size yourself. Stations and the overlay are coloured VFR, MVFR, IFR and LIFR, so a whole area reads in one look. WORKS OFFLINE A global basemap ships inside the app — no map account, no token, no connection. The last weather you fetched stays readable with no signal, and when the service is unreachable the app says so rather than pretending nothing is wrong. SCRUB THROUGH TIME Drag back through the last hours of observations and on to the TAF forecast frame, or press play to animate the loop. A station whose category changed since its previous report carries an arrow, so the map says which way the weather is going, not just where it is. STATION DETAILS Decoded METAR, the raw report with the group relevant to the current overlay highlighted, a trend chart of the last few hours, observation history, and the TAF. WEATHER ALONG A ROUTE Type two or more airports, navaids or US fixes — EFHK-EETN — to draw the great-circle track and read the reporting stations along it in flight order. Airports, heliports, navaids, fixes and runways are drawn on the globe, clustered where they are dense. WIND BARBS On the wind overlay every station draws a standard barb: half barb 5 kt, full barb 10, pennant 50, still coloured by flight category. FAVORITES AND NEARBY Pin the airfields you care about. Stations within 100 km are listed by distance, and when the closest field is not flyable the nearest one that is appears above the list. BUILT FOR READING QUICKLY Switch off roads, rivers, place names and other basemap detail so nothing competes with the weather. Light, dark or system appearance, with a basemap that follows it. Metric or US units — ceilings stay in feet and winds in knots, as aviation reports them everywhere. WIDGETS, SIRI AND SHORTCUTS Home Screen and Lock Screen widgets show a station's flight category, the age of its report and the wind, or a board of your favorites. Ask Siri for the weather at a station, the nearest VFR field, or the headwind and crosswind for each runway, estimated from the latest METAR. The same actions are in Shortcuts and on the Action button. ALSO INCLUDED Background refresh, so opening the app out of signal shows something recent. Airport search by code or name, worldwide, even for fields that do not report weather. DATA SOURCES Worldwide METAR and TAF from the AviationWeather.gov Data API, and Finnish automatic weather station observations from the Finnish Meteorological Institute (FMI), CC BY 4.0. Airports, runways, frequencies and navaids from OurAirports (public domain), and US fixes from the FAA's NASR data (public domain), shipped as an offline snapshot and refreshed from OurAirports. Basemap from Natural Earth (public domain). CxAVOK is for situational awareness and preflight familiarisation. It is not a substitute for an official weather briefing, and must not be used as your sole source of weather information for flight planning or in flight. Always consult your official aviation weather service.
