June 20, 200520 yr Hi Jim,The problem with the Decoded Weather repeated many times in both, in the Main and in the Wx Configurator ASV screens.Fortunately I could isolate the issue. It occurs when in the Wx string appears a
June 20, 200520 yr Commercial Member I think this is may be a case of what computer folks call "GIGO" i.e. garbage in, garbage out.Recent weather information when placed in a METAR should come after the QNH entry. I do not think that they are allowed to have "/" characters in them either.
June 20, 200520 yr Hi Dirk,Isn't this what we discovered a few days ago?!! I thought I was reading the same thread! I see its the same station SANT. I wish they would stop that code!No news from Damian so I say he is still at home. I was wishing for a Father's Day baby!Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg
June 20, 200520 yr Hi Jim,Yes this is the same matter I posted few days ago. But this time I discovered where the thing is!It is not frequent find in the
June 20, 200520 yr Indeed. Looks like a misformatted METAR. I don't know that HiFi can do much about this.
June 20, 200520 yr Commercial Member When I got home I checked all the aviation weather books I have, along with some of the better aviation weather web-sites and can find nothing which indicates that what you are seeing for SANT is valid. Yes, they may be producing it, but that doesn't make it valid.For example:- ICAO recent weather group (which allows the "RE" code) should come after QNH value and is considered supplementary information only and is only included depending on regional agreements.- In either the present weather group or the recent weather group a "/" character is not a valid separator for this type of information i.e. precipitation and obscuration.- You should never get "RE" codes in TAFs.The people at SANT therefore seem to be producing incorrectly formatted METARs (it happens). While ASV may interpret the provided METAR in the way you describe, the issue is with the source data, not ASV.
June 20, 200520 yr Hi Dirk,Remember you and I discovered this the other day!Please call up SANT and request that they stop using that code because it is messing up your ASV!!Hope this helps,JimActiveSky Sales and Supporthttp://www.hifisim.com/images/asv_dev_team.jpg http://www.hifisim.com/images/asv_proud_supporter.jpg
June 21, 200520 yr Commercial Member We're definitely going around in circles here.While I appreciate that you may be able to find one or two other instances where someone has entered a "/" in the significant present weather section of the METAR, it still does not make it a correctly formed ICAO (or North American) METAR.Check out http://www.met.tamu.edu/class/METAR/metar.html for a very good explanation of the ICAO and North American METAR codes.If you can find any information from a formal aviation weather organisation which details changes to the ICAO METAR standard to allow a "/" and use of "RE" in the significant present weather section I'd be interested to hear about it to add to my current understanding of the subject.
June 21, 200520 yr It seems the first slash found is interpreted as a temperature delimiter. Isn't it possible to add another check to see if the characters next to the slash are numerals (With an exception for M, minus)? If they are not numerals then discard and look for next slash.The indata might be bad but if there is a way to extract the real data then it should be no problem anyway.
June 21, 200520 yr Hi quantumleap,- I started this thread indicating were the problem resides remember? http://forums.avsim.net/user_files/120210.jpgWhat I try to say is that SANT is not the only weather station emitting these kinds of formatted METAR
