Abstract
Disclosed is a system for detecting uncertainty in temperature detection systems. The system includes a temperature sensor including a ground sheath and a central conductor surrounded by the ground sheath, the ground sheath and the central conductor being electrically coupled to one another through a temperature dependent resistive element. The system includes a controller connected to the temperature sensor and adapted to detect an electrical parameter of the temperature dependent resistive element, the controller operable upon execution to output an uncertainty indication when the electrical parameter of the temperature dependent resistive element is not within an expected value range based on an aircraft status indication, a historical value of the electrical parameter, and the electrical parameter.
