Hi everyone, This actually is not an RC problem but I thought I would post the question here first. I've been using RC4.3 with AS6.5 and noticing that wind gusts are not reported via ATIS (only the average wind is reported). I thought it was an AS problem at first, but after trying to set the weather to have gusts manually in FS, RC still did not report correctly. So I tried the default ATC which also did not report the wind correctly. So, the only thing I can think of is that FSUIPC is somehow suppressing the wind gusts although I have all the wind smoothing features off. Before I try the FSUIPC forum can someone tell me what settings they have for FSUIPC so I can try them? I know RC users are among the most knowledgeable on AS and FSUIPC.Thanks,Al

After more testing, it doesn't seem to be an FSUIPC problem. Shift-z shows that the wind does indeed increase amplitude periodically to the gust speed, whether using manually set weather in FS, FS real world weather or AS6.5. So the gusts aren't being suppressed, they're just not mentioned in the ATIS using either default ATC or RC. Anyone have any ideas?

Hi Al,RC reports weather as they in FS regardless of which software is producing that weather. I forgot the exact figure but I'm pretty sure that gusts are not reported unless the gust is greater than (14?) kts over the wind speed. So winds 16kts gusting to 24kts would still get reported only as "winds 16kts". In this example you will need gusts greater than 30kts (16 + 14) for it to be reported as "winds 16kts, gusting to 30kts".Sorry I couldn't be of more help, but in your tests make sure the gust is set at least 14kts above the normal wind speed.Subs

Thanks for your help Subs.You are right... RC reported gusts 15kt or more. Thanks! Default ATC still doesn't report gusts, but it doesn't matter I never use it as RC is much better. I guess I just imagined that default ATC used to report gusts, I guess it never did!Is the 15kt limit a design decision or an FS limitation? If possible it would be better to have RC report lower gusts in the 5-10kt range as well.Thanks,Al

It's the way it's reported in the real world.

By the way, I'm using the registered version of FSUIPC4. What have you guys found are the most realistic FSUIPC settings for realistic weather depiction by ASE while co-operating well with RC?

I was going to ask everyone the same thing! :) In between FSUIPC, ActiveSky, and FS, winds and visibility are the hardest settings to get 'right'. I like the windy turbulant bumps down low, but smoothing up high. Visibility graduation, but not those sudden changes in cloud layers. Then there are haze layers, fog layers, soft horizons, and the list keeps going on.I'd be happy to hear suggestions on everyone's settings too.Subs

I am a retired National Weather Service forecaster, and before that an observer. I'm not sure what the criteria are after the world decided to accept a uiniform of reporting weather. However, before the international agreement the way the US reported was as follows. You had to have a wind velocity of at least 6 knots before gusts were reportable. Meeting that criteria, the gust had to be at least 7 knots above the one minute average, which was defined as the current wind speed. After the international ageement I'm not sure about any changes. I have a copy of the new international weather reporting proocedures lying around the house somewhere. I'll try to find it and see what the current real world criteria are.Bob P

Hey Bob, That would be great to know. It sounds more reasonable for it to be 7kt than 15kt. It seems to me that if the metar says "27010G18" then the wind gusts were deemed "significant" enough to be mentioned, and if they're in the metar it only makes sense for them to be in the ATIS. Al

The new international criteria are as follows: The current wind speed is the average observed over the last two minutes. A gust is defined as a "rapid fluctuation" observed in the previous ten minutes with at least a ten knot variation between the lull observed during that period and the maximum observed. Note that the "lull" will be different (less) than the two minute average prevailing speed, the two minute speed being the average of the lull and the max during that period. There is no criteria for a minimum speed before gusts can be reported as there was in the US before the international agreement made everything uniform. Is everybody confused enough now?Bob P
