F4Wx – Real Weather Converter
-
there is something wrong : impossible to download any GFS
here the error message
-
@suhkoi69 Try to download the next line and see if that helps. I works for me when I get that message. If a no go, you just have to wait until NOAA have updated their files
-
@nil already tested but without success
-
first, I noticed it is little long to get this windows
and after choosing any GFS, I get the error message and it is the same for all theaters.
I try to load grib files in the the weather source option and nothing is loaded
has anyone tried to load a grib file in F4WX?

@suhkoi69
I’ve experienced that error in the past, but this version 1.05 seems to works perfectly. I use it regulary without problems. Try to unistall and re-install F4wx. The downloading waiting time could be shorten setting the downloading Forecast and interval with different values. I suggest to read BMS Technical Manual in your FalconBMS4.35 Docs directory (Chapter 7.4 F4Weather (F4Wx), pag 7-45. -
I just try it again and now it seems work fine
-
Sometimes, NOAA’s services are off line. I work with services provided online by the NGS, and at times they are out. Just have to sit back and wait…
-
Is there somewhere intuituve we can find background maps for all the theaters?
-
-
@lorikeolmin Thank you very much!
-
Will this work with the changes to 4.36 .fmap files or should we wait for an update to the applet?

@Ahmed I noticed something strange with F4WX: I downloaded a recent weather forecast from KTO and I think there is a mistake with the FMAP for time UTC +9
I think that 00:00 (UTC+9) is noon and not midnight because the temperatures are always higher at 00:00(UTC+9) than 12:00(UTC+9)~10°c (green area)
~20-25°c (yellow area)

I wonder if that could be related to what I have noticed which is the moon position does not match what it should actually be based on the time of the night.

@suhkoi69 BMS regardless of theater is Zulu time based. In order for things to work correctly with BMS 4.35/4.36 the hour for ‘Current Time’ and ‘BMS Time’ must be the same (for instance if ‘Current Time’ is 03:00 so also ‘BMS Time’ has to be 03:00).
In the past (pre BMS 4.35) adjustment for time zone was necessary but like said above it is not required anymore. -
@dcraig1 thanks oh I understand… I probably made a mistake when I saved without knowing it , my bad!
the BMS time in F4WX app may be confusing …according to my last check, all works fineI have understood my mistake : if by misfortune, you check “save sequence”, automaticcally, the BMS time will always appear the day1: 9:00 under the map even if you slide the time ruler…to avoid this stupid error, it would be better to replace BMS time by local time) and current time by BMS time (zulu time)

Hi all,
I haven’t had any time to dedicate to F4Wx or even monitoring this thread lately and it will take probably a few months until I have, so thanks to those helping people resolve their questions and issues lately.
Just a quick bit of information: F4Wx works with BMS 4.36 without the need for any updates. There is only one new feature of the weather engine introduced in 4.36 that F4Wx doesn’t take advantage of, yet.
As stated by some, since 4.35 the “sync with real timezone” option shouldn’t be used and I’ll remove it on the next update.
Due to my lack of time to dedicate to this, it is my idea to release the source code and host a repository for F4Wx on github, as my contribution to the community and so that whoever wants to contribute can do it through forks and pull requests. I just want to refactor some of the ugly code from many years ago before I do this. But I hope to do that at some point this year.

@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
