PROBLEM TO BE SOLVED: To provide a method for reducing de-icing heater error (DHE) in a total air temperature (TAT) probe. SOLUTION: Using the method, a nominal DHE function is obtained for a particular type of TAT probe as a nominal DHE function derived from a plurality of TAT probes of the particular type (505). A probe specific correction coefficient is calculated 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 (510). The predicted DHE at the first airflow is determined using the nominal DHE function derived from the plurality of TAT probes of the particular type. The probe specific correction coefficient is then stored and later used as a function of the probe specific correction coefficient to determine DHE for the individual TAT probe over a range of airflows (515).
