Confused in Cleveland–Weather Addon for MSFS

I recently received an email from one of my long-time blog readers asking my opinion regarding the recent announcement from REX on their upcoming release of Weather Force 2020 for Microsoft Flight Simulator.  With his permission, I’m going to post a portion of his email and then provide my opinions.

Hello Jerry,

I hope you and your family are well.  I’ve really enjoyed reading all your blog posts regarding the new Microsoft Flight Simulator 2020.  Like you, I’ve been excited about this new sim ever since I first learned about it.  But I’m slightly confused about a recent posting over on FSElite regarding a new add-on being developed by REX.  REX appears to be developing a weather add-on for MSFS, yet I thought (I think we all thought) MSFS had real world weather baked into the sim and weather add-ons from REX or Hi-Fi  Simulations (ActiveSky) would no longer be needed.  I’m curious what your opinions are on this subject?

Thanks again for all your efforts.

Confused in Cleveland,

Bill brings up a very valid point and one that I’ve taken some time to ponder.  He’s right!  From the very early news regarding the new Microsoft Flight Simulator we’ve been led to believe that the sim would include real-time weather injection that would be far superior to anything we’ve had as default in the past and there would be no need for a 3rd party add-on to provide this function.  Microsoft actually released a video in October of last year where they specifically discussed the new weather system within Microsoft Flight Simulator.

It is worth noting, at the present time…Microsoft is well aware and working to resolve the real-time weather functions within MSFS.  We expect to see a fix in the upcoming “Patch 2” release from Microsoft in the next few days that hopefully will address the weather (or lack thereof) issues within the new sim.  I personally remain extremely confident that in time (and that’s the operative word or phrase we must all understand) Microsoft will address all these issues/bugs and MSFS 2020 will be an amazing sim. 

The news article which Bill references from the FSElite site can be read here.  It’s also worth noting some fine print which REX discusses on their website“Even though the REX weather engine is pushing the proper temperatures and winds aloft data through to the simulator, due to core issues of Microsoft Flight Simulator, temperatures and winds aloft are not properly rendered yet. Microsoft & Asobo are aware of this issue. (September 13, 2020)” 

My personal opinion and certainly my initial plan is to take a “wait and see” attitude regarding all things weather in the new sim.  While it’s been an almost necessity to use an add-on weather engine in FSX/P3D, the jury is still out on whether this will remain true in Microsoft Flight Simulator 2020.  At the present time, I’m not even sure the default aircraft flight models are stable enough for real-world, real-time weather.  This is also currently being worked on and improvements to both aircraft aerodynamics, avionics and systems are part of this update #2 patch.

Interestingly enough, later today Hi-Fi Simulations commented on the future of their Active Sky product as it directly relates to Microsoft Flight Simulator.  This announcement was posted to FSElite and can be read here.  One of the key takeaways from that article reads, “Sadly, Damian did say that right now they are not aware of any way to bring weather interpretation into the simulator or what the possibilities will be.”  I find this statement rather interesting considering the REX product announcement discussed earlier.  I’ve tried both REX and Active Sky over the years and always found that Active Sky does a much better job with accurate weather interruption and injection.

Having said all this, does this still mean there will never be an opportunity for a 3rd party weather add-on in Microsoft Flight Simulator?  Where I personally believe some type of weather add-on might be beneficial is for those who enjoy flying with historical weather.  But I plan to allow Microsoft time to address the current issues with real-time weather functionality and go from there. 

I appreciate Bill taking the time to email me his question and would like to invite anyone else the opportunity to do the same.  You can contact me via email or by Discord private message

Thanks to all for taking the time to read my blog articles.  I hope you find them educational and entertaining.  Stay tuned for more…

Until next time…

Happy Flying!!!
