Every tool, one map
Prepare Flights combines weather, airspace, NOTAMs and route planning into a single interactive view — in your browser, with no install required.
METAR and TAF
Live observations per airport, refreshing every 5 minutes. METAR colour coding shows flight category (VFR, MVFR, BIR, IFR, LIFR) at a glance.
- Standard ICAO flight category colours
- TAF visualised on a timeline — see the whole period at once
- Badges for fog, freezing fog and other visibility hazards
- Wind direction and speed on each airport marker
Weather charts and overlays
Animated weather layers on the map — stack multiple overlays and scrub time up to 7 days ahead.
- Wind as animated particles at selectable flight levels
- Cloud cover split by low / mid / high (or combined)
- Rain and snow with intensity grading
- Icing risk (humidity- and temperature-derived)
- Turbulence based on vertical wind shear
- Convective activity (CAPE/LI) with CB/TCU markers and cloud tops
- MSL isobars with high/low pressure centres
SIGMETs, Nordic LLF and SWC charts
Official weather products on the same screen — no more hunting for separate PDFs.
- Real-time SIGMETs as polygons (NOAA AWC feed)
- Nordic Low Level Forecast (LLF) — FMI, SMHI, DMI and Met Norway
- Significant Weather Charts (SWC): Finland, Nordic, Europe
- Embedded directly on the map, no separate downloads
Radar and satellite
See showers approaching and clouds moving in near real time.
- RainViewer animated precipitation radar
- EUMETSAT satellite imagery
- NASA GIBS daily true-colour basemap
Airspace — with real-time activation
Terminal airspaces (TMA, CTR) and restricted areas (R/D/P) appear on the map, but more importantly you see which areas are active right now.
- TMA and CTR with frequencies and vertical limits
- R/D/P areas shaded by activation: active now, activates today, NOTAM-triggered
- Free routes and conditional routes (CDR)
- Powered by OpenAIP and Flyk, supplemented by live NOTAMs
NOTAMs
Active NOTAMs listed and pinned on the map. An AI-assisted summary helps you parse the hard-to-read messages — but always verify with the official source.
- Active NOTAMs along your route and at destination
- Plain-language summary via AI (note: does not replace the official source)
- Filter by time window and severity
Airport data
Over 22,000 airports worldwide. Deeper AIP-derived data for the Nordic countries.
- Runways: length, surface, approach lights, PAPI
- Automatic crosswind computation for the current METAR
- ATC frequencies: TWR, ATIS, APP, GND, RADAR
- Fuel grades (AVGAS 100LL, JET A-1, MOGAS)
- Operating hours from AIP — tower and AFIS hours
Printable briefing
One click and you have a printable briefing: the current map view plus appendices listing airspaces, NOTAMs, SIGMETs and airports along your route.
- Full-size map snapshot of the current view
- Appendices: active airspaces, NOTAMs, SIGMETs, route airports
- Printable A4 — take it to the cockpit
- Also savable as a PDF for sharing
Airgram — vertical cross-section
Draw a line on the map and get a vertical atmospheric cross-section over 24 hours — clouds, wind, icing and turbulence at a glance.
- 24-hour time axis
- Cloud layers, icing risk and turbulence
- Helps pick a safe flight level
