I didn't hear her talk about boots, but only listened once. As I recall,
Caravans do not have boots, and are not certificated for flight in known
ice. This is also true because those big struts also can pick up a lot of
ice. Prop de ice may be electric.

The only option for KI certification is through the installation of TKS,
which also protects the struts.

Caravans have an option for known-icing systems with boots (perhaps an
STC?). We've installed some.
