Abstract: A total air temperature probe (100) includes a probe head (102) having an airflow inlet (110), a main airflow outlet (112), a main probe head wall (108) and a flow separation bend wall (118). The flow separation bend wall (118) is opposite the main probe head wall (108) across a primary flow passage (120). A flow separation trip feature (122; 222) is defined on an interior surface of the main probe head wall (108) for tripping a boundary layer flow separation in flow in the primary flow passage (120), e.g., for reduction of deicing heater error.
