Abstract
In one embodiment, a method for health and trend monitoring for aircraft systems includes receiving, by a processor on the aircraft, a plurality of sensor signals from a respective plurality of sensors onboard the aircraft and determining a reference signal from a subset of the plurality of sensor signals. Next, each of the plurality of sensor signals is individually compared to the reference signal to provide a plurality of difference signals. Each of the plurality of difference signals is compared to a threshold value, and a maintenance message is provided for any respective sensor associated with any of the plurality of difference signals exceeding the threshold value. An aircraft employing the health and trend monitoring system is also disclosed.
