I am seeing RC4 reporting a constant temperature (and dewpoint) deviation of 10 degrees (high plus or minus 1 deg).This happens with default real weather, or any add on program.It does not appear to be an FSUIPC issue. For instance, I am sitting at KPRC in the default Cessna. The OAT gauge shows 35 deg F. The FSX real weather screen shows 35F/24F as the temp and dew point. On my network computer using Weatherset.exe that comes with FSUIPC the temp and dewpoint shows as 01C/-04C (34F/26F). RC reports temp / depoint as 11/05. I have let it sit for many minutes - results the same. Winds, pressures, clouds all appear correct.Using version 4.3.3845 on FSX Acceleration across a WideFS network (simconnect working too). Using FSUIPC version 4.634 (Nov 18, 2010). Problem is the same with ASE, REX or Open Clouds.Thanks for any input or help.Joe

make a log, instructions pinned to the top of the forum. duplicate the issue, and email me the log. also include what you think or fs says the temperature is. i'll see whats going on.jd
