What is it about?
The accumulation of snow on runways is a significant problem for airplane landings. This is because the existence of snow between the tires and runway reduces the friction coefficient and increases the braking distance required for landing.

Why is it important?
This study focuses on the interposition of snow between a landing unit with a rotating tire and a stainless-steel plate and investigates its influence on the friction coefficient.
Perspectives
The investigation uses electrical conductivity to observe the microscopic separation between the silicon rubber and stainless-steel plate. The results show that when using this method, the microscopic separation due to snow can be observed as a range between 0 (direct contact) and 1 (noncontact). In addition, we suggest that the friction mode that occurs during landing may be classified based on the state of snow.
