A multi-function air data probe comprises a probe stem having an outer surface that extends between a first end and an opposite second end, with the probe stem having a first cross-sectional diameter; and a probe head having an outer surface that extends between a proximal end and a distal end, wherein the proximal end of the probe head is coupled to the first end of the probe stem. The probe head has a second cross-sectional diameter that is larger than the first cross-sectional diameter of the probe stem. A plurality of multi-hole ports is located in the probe head, with the multi-hole ports extending into and through the probe stem. The air data probe is operative to make measurements used to determine one or more of angle of attack values, total pressure values, and static pressure values.
