Is that weather from the internet or weather from the sim?
If it is from the internet, there already exist several apps that can provide the same information, such as LNM or just doing a METAR query in Google. It’s nice to have it in the FMS, but if it doesn’t match the sim, then how useful is it?
It’s work in progress but you can chose from several sources. Funnily, if you chose “meteoblue (MSFS)” it still not matches in-sim weather. Matching the weather in the sim would be the only thing that made sense, though (IVAO / Vatsim aside).
Do you have any info about this? I saw in mcdu menu options for various metar and atis sources, but no option for actually getting any information about it.
For IFR planning you use the TAF not the METAR. Alternate requirements are based on the weather at your time of arrival plus or minus a specified time based on whether you are flying under part 91, 121, or 135.
Not really. I can’t test it and haven’t looked up the specs. My assumption is just that you can link to e. g. Navigraph via SimConnect if you have a subscription and their app running in the background.
You can use real world METAR, but it’s as much of a roll of the dice as to whether it will be accurate as the useless ATIS reports that rarely reflect conditions at the airport.
