OK Pete.Thanks very much

Thanks,for your fast answer.pete.Sorry there was à mistake in my question:not FSUIPC3 under FSX XP but FSUIPC 4 evidently.I'll try Active Sky,but how and where install it ? for information ,i use free version FSUIPC 4 . Regards

FSX under VISTA and FSUIPC 4 or XP and FSUIPC 3 Fliying on the network FSInn,cloud in front of the server ('MTO FSInn)the OAT don't decrease then altitude increasing .It's remain at ground temperature.Subsequaly,TAT and other engines parameters follow and are too hot or too high. Have you an Idéa ? Best regards
