so from what I have seen from my test flights, I don’t see any forecast data involved - It just looks like a metar engine is always acting - no cloud bands visible - it’s always just less cumulus or more cumulus “gathering” around the respective METAR stations - to be honest I have also installed the new update REX Weather Force 2020 - and this one seems to handle It better - the flight was only short - would have to test further. but that’s exactly what I don’t want anymore.
and here’s another example of the “great accurate METAR” (meant ironically if we’re talking about “accurate”):
Let’s take not only current stations (large airports) but also those that are no longer current - or are not occupied (at the moment) - smaller airports etc. - Let’s take an example of a small airport in our beautiful Austria
LOAR at 11:30:
ok there is no METAR data, the next current station is LOWG (the only active one in the radius selectable):
so what data are taken over there or what is interpolated there ? the station is 69 km (~37 nm) - in this radius there is no current data - so what is set or interpolated is what prevails there and that is 37 nm and there the weather can deviate by “worlds”.
By the way, with REX it looks the same - because REX also uses the data from the next active station and in this case LOWG !
and this is how it looked on the webcam at the same time:
So when you talk about the “suitability” of METAR, you should also take this into account and admit that it is also nothing for people who “first” operate VFR.
this is also one of the reasons why metar is not usable as a “visual” “option” for the SIM as the only source (which does not mean that you cannot use the values as a addition) !
The question is - do you want to have weather that is not really accurate but with sudden transitions - or weather that is not always accurate but smooth - would tend to the last option !!! (ONLY)!
And if the forecast is even better or more accurate in the future updates - there’s nothing to complain about!
The problem is still there with the visibility layer (or haze) - but you can read it out of the METAR - it would be important that everything comes from one “source” - otherwise a smooth transition is goodbye !
Besides, I would take these low level clouds (partly done before SU7) - because this “3D” fog is much easier to control or to set. !
And I must say REX MSFS2020 does the job really well - and if the update of unreal weather mod is also there - so where is the problem ? (I mean people who really want to have METAR based weather - can use these tools !!!)
