Besides the obvious protection of head and torso from rocks and trees, proponents of the airbag system point to the dynamics of the inverse segregation effect. That is the phenomenon that results in the biggest particles in a fluid in motion ending up on the surface after a certain amount of time. An inflated airbag increases the skier’s volume and decreases his density which causes floatation in an avalanche, as shown in snowfield tests with 90 kg dummies. It was also discovered that if the airbag was around the head and torso it
was more likely that the victim would be positioned head-up with less chance of face being buried.
