From FIS Freestyle wiki
4611 The Finish Area
The finish area must be flat and big enough to allow the competitor to come to a safe stop. It has to be fenced off completely. The fences should be laid out in a way that there is maximum visibility for officials, media and spectators.
4611.1 Finish line
The placement of the finish line is determined by the Head Judge and marked by painting a colored line across the bottom of the pipe and up the walls to the lip.
For a trick to count towards a competitors’ score the competitor must take off on or before the finish line.
