Hi iniBuilds team,

I'd like to ask about the recommended procedure for updating cruise winds in the A350 during long-haul flights, particularly when using ActiveSky FS alongside SimBrief.

In my current setup, I use ActiveSky FS as my weather engine and generate my SimBrief OFP using an ActiveSky weather snapshot. The A350 successfully imports the flight plan and its associated winds through the SimBrief integration.

However, several hours into a long-haul flight (e.g. 8–10 hours), the originally imported wind forecasts may no longer accurately reflect the conditions being depicted by ActiveSky.

With PMDG's 737 and 777, I can address this by exporting updated winds from ActiveSky directly into the aircraft's dedicated WX directory. The aircraft can then import the updated wind data without regenerating the SimBrief flight plan.

As far as I'm aware, the iniBuilds A350 doesn't offer an equivalent ActiveSky wind import mechanism.

My questions are:

1. Real-time weather: What is the recommended procedure for refreshing the A350's cruise winds several hours into a flight? Is regenerating the original SimBrief OFP and requesting the winds again through the FMS the intended approach?

2. Historical weather: How should this be handled when using ActiveSky's historical weather? For example, if I'm flying yesterday's weather, the original SimBrief OFP was generated using an ActiveSky snapshot corresponding to the departure time. Uploading a new snapshot several hours into the flight would require changing the OFP's departure time to match the snapshot, which would shift the forecast times for all subsequent waypoints.

3. Direct integration: Does the A350 currently support any method of importing updated wind data directly from ActiveSky, or are there plans to introduce such functionality?

Ideally, I'm looking for a way to refresh the FMS wind predictions during cruise without manually entering winds at individual waypoints, replacing the active flight plan, or introducing inconsistencies between the simulated weather and the OFP.

I'd appreciate any guidance on the intended workflow or currently supported alternatives.

Thanks in advance!

Great question. I'll forwared this to the dev team for further clarification.

If it is currently not supported, this is definitely something I think we should investigate for V2.

Appreciate your time 🙂
