Publication number: 20160167792Abstract: An anti-icing system for an aircraft structure includes a cavity that has an exterior surface subject to ice accretion and a bleed source that is configured to provide a fluid to the cavity via a duct. The system includes multiple temperature sensors, disposed at the aircraft structure, with each temperature sensor configured to detect a temperature associated with an aircraft structure location. A controller is in communication with the temperature sensors. The controller is programmed to compare outputs of the temperature sensors and to determine a temperature sensor fault condition.Type: ApplicationFiled: December 4, 2015Publication date: June 16, 2016Inventors: Michael D.
