International WX briefing

Sun Apr 14, 2019 8:22 pm

What website(s) do international long haul pilots use for weather briefings? Is there a single source website for briefing flights to anywhere around the world similar to this: https://flightplanning.navcanada.ca/ or this: https://www.aviationweather.gov/adds/? Ie: do you have to google WAFC london sigwx charts or any other specific chart that you want every time, or is it all in one place somewhere?

I can only speak for our operation but we don't normally need to actively look for weather information before we go. It is provided for us.

The relevant METARs and TAFs are part of the briefing package, which also includes a pile of SigWX charts, NOTAMs, the flight plan, fuel statistics for the route, etc... The package can be over a hundred pages on a long flight, most of which is NOTAMs. We can download the briefing package, and once at dispatch or at the aircraft, we get the whole thing on paper. (Many if not most large operators are moving towards fully or almost fully paperless.)

Of course, whoever compiled the briefing package got the information from somewhere, but I don't know what sources were used. I assume there is some commercial aviation information provider involved.

In flight, we can get METARs, TAFs and ATIS via datalink.

I do use the Aeroweather app on occasion but there is no real need to.

Typical;y the packaging of weather is a dispatch function for the respective airline. If on the otherhand you are a corporate operator that function may utilize the service of a flight planing service provider such as Jeppesen, Universal, or Arinc and provide the crew with a complete package that includes METARS, TAFS, NOTAMS and a very nice set of graphic WXR charts. One function on the Jeppesen, JetPlan website allows you to select a Great Circle sample of weather for each airport you would fly close to. In addition, you would need specific WXR for any ETP alternates which might fall significantly beyond your flight plan routings. Normal procedures would call for dispatch to monitor the ETP alternate wxr for changes that would eliminate its use for a diversion. Most dispatch operations will deliver a coast out and coast in (destination) update. By the time its over there are usually one or two fewer trees standing.
