At this time no released version of FlightGear has any glider launching methods.  Working winch launches and even multiplayer aerotows have however been successfully tested and should hopefully appear in the next release.  For now, to fly a glider you must set it up to begin in the air.  For an example of how to do this see the related article called [[Starting in the Air]], or see the start file for the Schweizer 2-33 (called sgs233-set.xml).
At this time no released version of FlightGear has any glider launching methods.  Working winch launches and even multiplayer aerotows have however been successfully tested, the code is in CVS now (see [[Doing_aerotow_over_the_net]]) and will be included in the next release.  If you cannot use CVS though, to go gliding you must start up in the air.  For an example of how to do this see the related article called [[Starting in the Air]], or see the start file for the Schweizer 2-33 (called sgs233-set.xml).


Thermals and sinks are modeled, but they must be defined individually in a thermal scenario file.  To see how this is done it would be best to examine the file called data/AI/thermal_demo.xml, which sets up 11 thermals and 6 sinks around San Francisco Bay.  To learn more about AI scenarios in general, see the related article called [[AI Systems]].  Note that the thermals and sinks exist independently of FlightGear's weather system, so it's possible to have cloud layers that don't match your thermal heights.  To prevent this you may want to manually set the cloud layers to match your thermals.
