Big air is the newest discipline in Olympic snowboard, having made its debut at the 2018 Winter Games.
Athletes ride down a ramp and perform one trick when they launch into the air and land in a designated zone.
There are three jumps to execute, with the scores from two highest-scoring tricks combined to determine the athlete's overall ranking.
There are minimum height and length specifications for the jump to be Olympic standard. The big air structure at Milano Cortina's Livigno Snow Park has a total length of 225 metres, a peak height of 40 metres and an average gradient of 28%.
Athletes who qualify for either big air or slopestyle will also compete in the other discipline.
