ABSTRACT:
An improved air data sensing probe de-icing system that provides for dramatically increased reliability and lifespan, utilizing solid-state heating elements that are electrically connected in parallel and having inherent temperature control, where each of the heating elements are able to provide full system power in the event of failure of one of the heating elements such that system redundancy and de-rating is achieved.
