METAR decoding discrepancies

Featured Replies

Hey guys, 

 

Just landed in Calcutta where I was very much looking forward to a lovely cat3 ILS approach in poor visibility however this didnt go as planned...
The visibility generated was closer to 10000m than 50m as per the METAR, and the weather report (in the FSX menu) was saying as much.
Heres the METAR given by IVAO :

VECC 100120Z 00000KT 0000 R19L/M0050 RMID/M0050 R01R/M0050 FG VV/// 11/10 Q1015 NOSIG 

I have been flying eith the NOAA server as primary source of weather.
After landing I tried to select IVAO instead, and Tada !

Thought it was worth mentionning to the dev team! Or did I do something wrong?


Cheers, best investment I've made for a weather software EVER. ANd I mean it. Thank you!

Did you specify your Destination?

 

I have just tested your METAR and with a reported visibility of 0000 the LWE will give 50 metres visibility on the surface.

 

Just make sure you are running the latest release version and you always specify your Destination weather.

 

You should use the Destination weather report which will confirm to you what the weather is at your destination and will even place an (Actual) on the first line to indicate the weather in the sim has been confirmed. Best read and follow the Recommended Practices and all should be OK. Bets to stick to the NOAA METARs as well. The weather only changed because you updated it on the ground after landing so my guess is you forgot to specify your destination to the LWE.

 

Also make sure you do not fly with accelerated time without FSUIPC4 installed.

 

I will go to the VECC site and double check but the METAR decodes fine when imported as a GLOB.

OK, just tried VECC with the past and current METARs and all is well. Got 50 metre visibility with the old and 2400 metre visibility with the current 101120Z NOAA METAR.

You should also post what time it was as the IVAO METAR could have been out of date.

 

You will find the downloaded METARs in your OpusWeather.txt file.

 

I trust you weren't using some other source to tell you what weather to expect.

 

ALL the information is in Opus and you need not check anywhere else.

P.S.

 

I checked your METAR above and that decoded OK. But without knowing what the OpusWeather.txt file was at the time when you was using NOAA I cannot say why the surface visibility didn't match the IVAO METAR.

 

I cant really do anything else as the 'actual' METARs in your OpusWeather.txt file, the ones producing the weather are unknown.

 

If it happens again just send me or post your OpusWeather.txt file, but please monitor the Opus weather reports.
