WhiteScout for Freerider
is an unique smartphone app, which estimates the risk of triggering an avalanche or slab by skiing down a given route. The app is always positioned to user's present location and this is why it works across Europe. With the help of risk-analysis the danger of the tour is calculated by only one click.
As a result a probabilistic "stop or go"- decision will be displayed. The remaining residual risk is defined by the following formula:
Accepted residual risk = risk potential / precautionary measures
The avalanche bulletin represents hereby the risk potential. The precautionary measures (slope inclination and exposition) are restricting the possibilities for skiing down steep slopes, which deemed to be risky in relation to the avalanche bulletin ratio. The model follows the elementary reduction method described in specialized avalanche literature by mountain guide Werner Munter of Switzerland.
WhiteScout, if used properly and permanently, can reduce todays relationship from 1 death by avalanches per 50'000 ski slopes to 1:100'000 in future.
