Abstract
Methods and Systems for health-monitoring of a multi-channel pressure transducer of a gas turbine engine are described. The method comprises monitoring a deviation between a first channel and a second channel of a multi-channel pressure transducer over time, determining a rate of change of the deviation, extrapolating a trend over time based on the rate of change of the deviation to predict when the deviation will reach a threshold, and triggering a maintenance action for the pressure transducer based on the trend.
