Hi team,

First of all, thank you for creating and maintaining such an incredible tool for the flight simulation community.

I would like to report a recurring issue regarding historical weather data integration when dispatching a flight.

Whenever I generate a flight plan using a historical departure time (for instance, creating a flight plan on Sept 25th in the morning, but setting the Scheduled Time of Departure to Sept 24th at 16:45 UTC), the OFP generates with the real-time (IRL) METARs, TAFs, and SIGMETs corresponding to the moment the plan was generated, rather than fetching the historical weather data matching the scheduled departure date and time.

This behavior occurs consistently whenever planning flights with historical weather from the past 24 hours.

Would it be possible to adjust this so that the generated OFP fetches the historical METAR/TAF/SIGMET data corresponding to the departure date and time set in the flight options, rather than the current real-world generation time? This would greatly enhance realism for delayed or historical flights.

Thank you very much for your time and continued hard work!

Best regards,

Hélène

Good luck! This has been asked for several times since MSFS24 has introduced 24h historical weather. No answer, no acknowledgment. I’ll eat my words if you get an answer…you’ll be my hero! 😉

This is one of the original posts nearly TWO years ago.

> Hi Navigraph Team, I hope you’re all doing well. I wanted to share a feature idea that I think could really help a lot of us using SimBrief with MSFS2024. With the latest updates in MSFS2024, the simulator now links weather directly to the in-game time. While this adds great realism, it’s causing some issues for tools like SimBrief that rely on real-time weather data. For example, if you’re based in North America but want to fly during daytime hours in Europe, SimBrief pulls the current nightt…

So frustrating.
