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.

A method for health and trend monitoring for aircraft systems, comprising:
- receiving, by a processor on the aircraft, a plurality of sensor signals from a respective plurality of sensors onboard the aircraft;
- determining a reference signal from a subset of the plurality of sensor signals;
- individually comparing each of the plurality of sensor signals to the reference signal to provide a plurality of difference signals, each of the plurality of differences signal associated with a respective sensor of the plurality of sensors;
- comparing each of the plurality of difference signals to a threshold value;
- and
- providing a maintenance message for any respective sensor associated with any of the plurality of difference signals exceeding the threshold value.
A health and trend monitoring system for aircraft systems, comprising:
- a plurality of sensors each providing sensor signal;
- a reference signal generator providing a reference signal from a subset of the sensor signals;
- a comparator associated with each sensor for comparing a respective sensor signal to the reference signal to provide difference signal associated with the respective sensor providing the sensor signal;
- a monitor associated with each sensor for comparing the difference signal to a threshold value and for generating a maintenance message for the respective sensor when the difference signal exceeding the threshold value.
An aircraft, comprising:
- a plurality of sub-systems;
- a health and trend monitoring system associated with one or more of the plurality of sub-systems, comprising:
- a plurality of sensors each providing sensor signal;
- a reference signal generator providing a reference signal from a subset of the sensor signals;
- a comparator associated with each sensor for comparing a respective sensor signal to the reference signal to provide difference signal associated with the respective sensor providing the sensor signal;
- a monitor associated with each sensor for comparing the difference signal to a threshold value and for generating a maintenance message for the respective sensor when the difference signal exceeding the threshold value.
