A shader is a set of software instructions, which is used primarily to calculate rendering effects on graphics hardware, like water reflections and shadows.
Shaders in FlightGear
Currently some new shaders are available in GIT, including (sun on) water reflections, snow at altitude, the urban shader, the landmass shader, and the crop texture shader. The random trees in the scenery are alse generated making use of shaders. These are all classified as material shaders.
With the switch from PLIB to OSG, as of version 1.9, FlightGear lost its shadows.
The shaders can be en-/disabled through the View > Rendering Options dialog.
