The OSG's osg::GraphicsContext::Traits data structure that is passed to the osgViewer GraphicsWindow subsystem has a bool vsync that defaults to true. Under Windows and OSX there is support for enabling vsync, but alas there isn't any such feature under GLX so Linux etc. have to rely upon the driver to do it. Applications have limit the frame rate themselves by gating the main frame loop but this won't by sync'd to the vertical refresh unless vsync is enabled in the driver. It's likely that Flighgear is simply holding back the framerate to 60 hrz.
