Abstract:
1. A method of reducing de-icing heater error (DHE) in total air temperature (TAT) probes, the method comprising: using processing circuitry to obtain a nominal DHE function derived from a plurality of TAT probes of a particular type; using the processing circuitry to calculate a probe specific correction coefficient for an individual TAT probe of the particular type as a function of a measured DHE at a first airflow and a predicted DHE at the first airflow, the predicted DHE at the first airflow being determined using the nominal DHE function derived from the plurality of TAT probes of the particular type; and using the processing circuitry to determine de-icing heater error with the individual TAT probe over a range of airflows as a function of the probe specific correction coefficient.
