F4Wx – Real Weather Converter
-
@Ahmed Thanks for your contribution!
I did realize an issue with view distance in sunny weather where the visibility was very poor given the clear sky…
Maybe something to check later on (might also be a faulty data input).Cheers

@MaxWaldorf This probably has to do with what I mention is not implemented yet and BMS is just filling for that. In any case I’d have to see the result. Hazy skies while still being clear of clouds are a thing irl.

@Ahmed Agreed with hazy clear skies! @MaxWaldorf Flight instructor hat on, this weather phenomenon is usually more often by the visibility restriction called mist (coded BR, short for French “brume” in the international METAR system). Laypersons often call drizzle “misting” but it is not the same thing. Usually mist is a 3-5sm mile visibility range, but technically it can go down to 1km.
One other thing is that real life aviation systems max out at 10sm visibility, where actual visibility can be and usually is much further than that.

No it’s not
The only thing in 4.36 not implemented in F4Wx is fog altitude
In this case this is a visibility issue so I would call that a bug

Hi, I’m having an issue downloading weather: the box where choose download time it’s completely empty. My ver it’s 1.05….

@Ahmed
HI, just to report to You that, after few days F4Wx it’s unusable. After choosing “download weather, the window with files to pick it’s completely empty. Someone else experiencing same? -
@Gancio Just tried it and works as expected
- Choose theater
2.Download Weather - New window pops up, choose a line and download starts, dont take the first or second line
- Choose theater

@Toner
Many thanks for reply Toner, the problem is that the box, from where usually I choose the file it’s completely empty. This happen from a couple of days. I’m using F4Wx since it’s out.
Whichever theater I choose, after asking for the download, the window with the files with the timetables is empty, as if it did not receive any files to be downloaded -
@Ahmed
Hi Ahmed, after a little investigation involving a friend, I tried to download and install F4Wx on a laptop, which I don’t use for the simulator. On this computer everything works, I download the gfs files and the window is full of files to choose from. . Has anything changed since the first days of August? In those days F4Wx worked perfectly, I’ve been out for holidays and now no longer on the computer I use for the simulator. Thank you -
I see no issue on my system.
If you are still having this issue, I suggest that you make sure that you are not blocking F4Wx on your firewall or something.

@Ahmed
Many thanks Hamed for Your reply. I’m not at home at the moment, I will check Thursday. I let You know.
Many thanks -
@Ahmed
thanks for the suggestion, unfortunately the problem is not there, (firewall or antivirus) could it be that using windows 7 something happened recently that no longer supports the download processes? I use F4Wx on the laptop running W10 and it works perfectly. -
@Gancio why dont upgrade to win 10
Should be free of charge -
@Toner
Hi toner, thanks for your reply. No I can’t. I play BMS within a full scale cockpit that it was built through many years. Unfortunately some hardware/software can’t be updated “ free of charge” to last most “fast” OS.

@Gancio OK then you can only try the workaround with win 7 and save the maps on a stick and copy to your BMS folder

The new fog altitude feature, added with version 4.6, interacts with the visibility maps: as currently the fog altitudes are zero at each generated FMAP; this involves that the visibility criteria are never applied…
from what I understand, it is difficult to get this dataif is there no possibility to extract fog altitude from real-world GRIB data, couldn’t we to apply a criteria scaled according to visibility data ?

Indeed, this is currently not being populated by F4Wx, as it needs to be updated to make avail of this new BMS feature. The issue I have seen, is that GRIB files from NOAA don’t contain enough data from NOAA to estimate these fog layers.
I have limited time, so I haven’t been able to do much research on how to estimate it from existing data. If anyone has any suggestions or even a basic ROT that can be used, I’d be more than happy to update F4Wx to use that.

Hi everyone. I am a newcomer of Falcon BMS. Can someone send me a copy of F4Wx? I can’t open either of the download link as both of them are blocked. Many thanks.

If f4wx still use the previous version numbering in the header (4.35 one …will edit this post to give the right one) then the fog altitude will be automatically populated like the previous one I.e. base of cumulus clouds
@Ahmed just make sure f4wx writes the correct version number in the header

Yep, it is still using the old version (5), as I haven’t had time to make any updates for a very long time. Can’t offer yet any ETA on any updates to use the new options (and also can’t think of any way of estimating fog altitude from available GRIB data, any ideas welcome by pm)
