As one of the more popular winter sports in the Paralympic Winter Games, Paralympic Alpine Skiing is governed by the IPC (International Paralympic Committee) under the FIS (International Ski Federation).
What was once limited to above-knee amputees, disabled skiers can now compete for medals in three categories: Sitting, Standing, and Visually Impaired. Each category is divided into three to seven classes and possibly subdivided into two to three sub-classes.
In an attempt to place the different degrees of disabled athletes on a level playing field, times are compared by a "factor system" by multiplying the time of each racer in a class or subclass by a fixed number resulting in what's know as "adjusted time". This "adjusted time" appears on a results list for disabled ski races.
