This work presents the results of an analytical study designed to evaluate whether the B-1B hot-air windshield de-icing/anti-icing system, operating independently from the embedded electrical resistance system, was capable of adequately meeting de-icing and anti-icing requirements. Two icing scenarios were considered in loiter, landing and ground/taxi modes of operation. The results indicate that in a loiter and landing mode, the system capability ranges from marginal to adequate. Additional work is needed to expand the applicability of the analysis mode to ground/taxi conditions.
