Abstract
A method and apparatus for testing a duct leak detection system of an aircraft is disclosed. A sensor of the duct leak detection system is selected at an interface of the duct leak detection system. An alternating current is sent through the selected sensor and a resistance of the selected sensor is measured using the alternating current. An indicative signal is generated at the interface when the measured resistance of the selected sensor is outside of a specification of the selected sensor.
