Zusammenfassung:	Disclosed is a short detection system for an aircraft. The system includes a pair of alternating current sources defined by respective frequencies being offset by a predetermined value. The system includes a pair of sensor systems including respective measurement circuits coupled to respective sensor apparatuses to measure at least one parameter of an environment. The system includes an alternating current measurement system that includes a low pass filter having a cutoff frequency greater than the predetermined value such that a beat indicative of a difference between the respective frequencies passed through the pair of sensor systems is isolated by the low pass filter. The system indicates a short among the pair of sensor systems when the beat is present.
