METAR from KPHL on 3/4/2016 while snowing

Postby llsouder » Sat Mar 05, 2016 12:28 am

KPHL 041200Z 05009KT 3/4SM -SN BKN009 OVC029 00/M03 A3011 RMK AO2 P0000 T00001028 RVRNO

I put this into a <scenario> and I thought I would see snow, but nothing really happened.

How am I suppose to add METAR to flightgear. When I select "manual" from the combobox I still cannot type into the boxes.



Here is one from KACY.

One way that works (or at least used to work...) is to pass --metar on the fgfs command line. I have used this with success, for instance:
Code: Select all
--metar=LOWI 070956Z 35019KT 10SM FEW023 11/07 A2977 RMK AO2 SLP080 T01060067

(setting a nice crosswind at LOWI)

Which version of Flightgear? I believe all precipitation is broken in 2016.1.1.

Ah, sorry. I read too quickly and didn't see the actual problem was not being able to see snow.

rominet:
You are correct one of one of my problems was getting the metar into the system. Your input was helpful, thx.

sanhozay:
I am using the latest development git check out , 2016.02...

On the subject of "manual input" should I be able to use the GUI to type in values? I see the "I" text input cursor.

Maybe it is KDE holding me back? or is a bug in the newest code?

Yes, you should be able to edit the METAR string. Sometimes those dialogs stop responding to input and close and reopen resets it.

I checked latest 2016.2.0 and precipitation is broken.

I confirmed that closing then re-opening the weather dialog allows me to type in the METAR. Input not working is very consistent. I has never worked the first time I select it.
Precipitation works on version 3.4 . It did snow and the wind blew the snow in the correct direction. That is super cool.

https://sourceforge.net/p/flightgear/codetickets/1850/
After reading the bug report about the precipitation I tried the possible fix and found that it does work. So far I do not have any other issues by adding the "if statement" but I look closer at the code tomorrow

In order to get --metar to work, in my case I had to disable the real weather fetch:
Code: Select all
--metar="LOWI 070956Z 35019KT 10SM FEW023 11/07 A2977 RMK AO2 SLP080 T01060067"
--disable-real-weather-fetch

Ah, right. Thanks for the precision! I had --disable-real-weather-fetch commented out before a few different --metar lines also commented out in my config, so I probably came to the same conclusion as you. But it was a while ago and I had forgotten this was necessary. I'd even call it a bug (no idea if it has been reported, though)...

Glad to know you have it working!

I have filed a merge request that fixes this (i.e., it makes --metar automatically imply --disable-real-weather-fetch).

The request has been merged last night (thanks, Torsten!), therefore if you are using FlightGear at commit 0cfa4ced9cd5e2ec26e753ddd5f61da7558221a6 or later (i.e., the fix is in current FG 2016.2.0), you can use --metar=... without having to redundantly specify --disable-real-weather-fetch, and things should work just as expected.

Interesting, I have 2016.1.1, I can input the METAR data when I select "manual" from the menu, and the weather is pretty identical, but just never noticed precipitation.
I do get a 'realistic weather not supported by METAR" message though after I assume leaving my current tile. I guess similar situation yet a little different?

What happens if you move outside of that tile on a long haul, for example? Under current settings in 2016.1.1 and with the new fix for the 2.0?
Will it stay with the same weather from KPHL to Dubai for example? Or will it change with the regional changes?

Do I need to download 2016.2.0 now for this change instead of keeping 2016.1.1? As mentioned by Sanhozay precipitation not working; in FG 2016.1.1, why did they release it as a new complete version then?

One of the coolest things in FG 3.6 I've experienced is leaving Dubai in dry clear conditions and arriving Buenos Aires in a massive chain of thunderstorms and pouring rain, gusting crosswinds and low visibility.

flightgear has changed to the "agile" form of development... i think others might know it as "release early, release often"... in any case, releases are done on specific calendar times, now... IIRC, that will be every three months so that there are four releases per year... there are no more "release candidates", either... there is the code in the repo which will be tagged for the next release when that time arrives... it is possible that there might be intermediate releases if a huge problem shows up and can be fixed but that is unlikely as the next public release will be available in three months...

"Why not?" said Gurder.
