Hi allI was thinking ,flightsim lacks some important weather phenomenons like downdrafts,turbulence around rising ground etc. Is it possible to add these as permanent effects at key locations? I have been playing around at Madeira which acording to Jeppesen the airfield is subject to turbulence due to the location (side of a hill next to the sea)so would it be possible to make a bgl that houses weather effects similar to the soaring thermals? i dont know if downdrafts are modelled or if they can be created but it would make the landings more challenging.I find that it is just to easy at times to stay on the localiser/glide compared with when i fly the pa28 for real! any comments ideasbest Keith

Keith,it is possible to add some thermics but dynamics is modeled poorly. You won't get everything as in nature but at least something can be done. Check documentation here:http://www.scasm.de/doc/sca_road.htm#stwAnd check the program Thermiek and the information/tutorial here:http://www.virtualsoaring.org/library/Reference/thermal.htmHope it helps!Best regards,Goran BrumenFS Slovenija 2002 teamhttp://slovenia.avsim.net

thanks for the advice,will spend some time reading and report back!cheers keith
