How to use this page · tap any ? for a full explanation
- Enter the route: departure, destination, an alternate and up to four stops (ICAO codes).
- Enter the departure time in UTC and the flight time. Pick a window (± 1–3 h) around each ETA.
- Add cruise altitude and TAS to get your profile drawn in the cross-section, with TOC / TOD and minutes of icing, turbulence and cloud on your path.
- Build briefing. Each airport card gives the METAR (issued), our hourly guidance around the ETA, hazards, winds aloft and limits (below alternate / below landing).
- The cross-section shows the weather you would meet at each point at the time you get there: cloud, icing arcs, turbulence scores, tropopause, freezing level, terrain.
- Print or save the page. Tags show what is issued and what is MeteoFrontier guidance; official TAFs, GFAs, SIGMETs, PIREPs and NOTAMs are not included.
