  • Total air temperature probe and method for reducing de-icing/anti-icing heater error
    Patent number: 8392141
    Abstract: A method of reducing de-icing heater error (DHE) in total air temperature (TAT) probes is provided. Using the method, a nominal DHE function is obtained for a particular type of TAT probe, with the nominal DHE function having been derived from a plurality of TAT probes of the particular type. 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. 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 for later use, or used to determine DHE with the individual TAT probe over a range of airflows as a function of the probe specific correction coefficient.
