Ski plane

A bush airplane is a general aviation aircraft used to provide unscheduled passenger and freight services to remote, undeveloped areas of a country, such as the Canadian north (or bush), Alaskan tundra, the African bush, or the Australian Outback. They are used where ground transportation infrastructure is inadequate or does not exist.

Since a bush plane is defined by how it's used, a wide variety of different aircraft with different configurations have been used over the years as such, however experience has shown certain traits to be desirable, and so appear frequently, especially on aircraft specifically designed as bush planes. None of these traits are mandatory - merely that they are commonly seen features of bush planes.
