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.

Here is a discussion of the Caravan anti-ice system:

http://www.ainonline.com/Issues/03_0...vanicing_1.htm

Included in the above is:

"The aircraft’s anti-icing system includes operational leading-edge de-
ice boots on the wings and horizontal and vertical stabilizers, propeller
anti-ice boots, windshield anti-ice panel, heated pitot-static and stall-
warning systems, a standby electrical system, a wing ice-detection light
and an engine inertial separator."

TKS is an option.

A year ago, an AD was issued:

"Effective February 22, operators are required to install a pilot-assist
handle to allow inspection of the upper surface of the wing and de-icing
boots for the landing gear struts and cargo pod by June 27"

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

Boots are an acceptable alternative.

Also note that in the cited article, a Cessna spokesman said:

“There has never been a civilian airplane built that can withstand flight
into continuous known icing under moderate or severe conditions,” and
“it’s the pilot’s responsibility to recognize and exit those conditions.”
