Hello everyone

 

When I use time compression the time is going 4/8 times faster so I cannot get realistic weather. What I mean is that for example navigraph shows KJFK 300 at 8 knots,

obviously in the sim this real world data cant be shown because Im forward few hours. So is there a way where I can fasten the sim but still have the IRL time and weather?

 

I have thought about setting the real weather options when Im doing the arrival but it wouldnt work for gods sake.

Simply plan your flights that you arrive in real time at the current time of the real world. This means that you will sometimes simply have to start with historic weather and fast forward until you fly in the current time again.

 

What you have to keep in mind though that if you plan with simbrief you have to plan the flight AHEAD.

So for example if you plan to do a long haul that starts at lets say May 23 10UTC and ends at 22UTC and you have time to fly from 19UTC to 2230UTC then you do your Simbrief planning BEFORE 10UTC and then start the flight at 19UTC with the simtime set to the 10UTC where it uses the wheather that was prevalent at the time. Then you do your flight, speed up until you are in synch with the real world again. 

This way you will have the correct weather you need.

 

If we're talking about MSFS2024, then there's no issue, since the time we see on the clock doesn't speed up, even though the simulation itself is accelerated.
Besides, when will the bug be fixed, using historical weather solves this problem.

In 2020 and so I assume 2024, when you're using live weather, any time in the future gets the present weather.  It doesn't matter if you take off "now", and time accelerate so that you arrive 3 hours in the future - with live weather turned on, meteoblue is still providing live weather based on the real-world "now".  It doesn't know how to provide anything else.

I can't talk about 2024 but in 2020 it definitely does not, at least for me. Basically when I turn on time acceleration - let that be the Ini 350 or PMDG aircraft etc - The live weather option turns off, and when I tick it again it goes stupid and provide anything but the real weather.

To be fair if there would be no wind and/or clear skies I wouldn't annoy myself that much, but when I find myself on short final 30kts crosswind or I can't see anything at CAT 1 minimums with the real METAR showing fine weather - and the live weather option turned on - it really makes me question if it was worth flying X hours that day and not buying xp.

Thank you, this seems like a good idea. I will try it.

That's strange.  This definitely does not happen for me; live weather does not get turned off by time acceleration in 2020.  There's hardly a flight I don't use it on, and I've never lost live weather once.  I wonder if there is a setting that affects it?  A location in the world?  Or the length of time that acceleration is used?  (I do shorter sim flights usually so I'm not more than an hour or two into the future upon arrival).
