A total air temperature data probe, the probe comprising: a probe base; and a probe body having a leading edge and a trailing edge and extending from the probe base along a first axis, the probe body comprising: a first interior airflow passage comprising a first annulus aligned with the first axis; a second interior airflow passage comprising a second annulus aligned with the first axis; and a tubular heat shield separating the first annulus from the second annulus; wherein the second annulus is defined by a space between the tubular heat shield and an interior wall of the probe body; a temperature sensor positioned within the first annulus; a heating element positioned within the second annulus; a notched intake port positioned at a distal end of the probe body, wherein the probe body provides a conductive thermal path from the heating element to the notched intake port, the notched intake port including an open channel extending inward from a first face of the distal end into an intake aperture of the probe body opening to both the first annulus and the second annulus, and a cutaway region that defines a recessed second face inset from the first face and exposes the open channel at least partially from the leading edge; a weep hole penetrating from a base of the notched intake port to the trailing edge of the probe body; and wherein the notched intake port further comprises a slot inset from the recessed second face that traverses across at least a portion of the intake aperture perpendicularly to the open channel. a probe base; and a probe body having a leading edge and a trailing edge and extending from the probe base along a first axis, the probe body comprising: a first interior airflow passage comprising a first annulus aligned with the first axis; a second interior airflow passage comprising a second annulus aligned with the first axis; and a tubular heat shield separating the first annulus from the second annulus; wherein the second annulus is defined by a space between the tubular heat shield and an interior wall of the probe body; a temperature sensor positioned within the first annulus; a heating element positioned within the second annulus; a notched intake port positioned at a distal end of the probe body, wherein the probe body provides a conductive thermal path from the heating element to the notched intake port, the notched intake port including an open channel extending inward from a first face of the distal end into an intake aperture of the probe body opening to both the first annulus and the second annulus, and a cutaway region that defines a recessed second face inset from the first face and exposes the open channel at least partially from the leading edge; a weep hole penetrating from a base of the notched intake port to the trailing edge of the probe body; and wherein the notched intake port further comprises a slot inset from the recessed second face that traverses across at least a portion of the intake aperture perpendicularly to the open channel. a first interior airflow passage comprising a first annulus aligned with the first axis; a second interior airflow passage comprising a second annulus aligned with the first axis; and a tubular heat shield separating the first annulus from the second annulus; wherein the second annulus is defined by a space between the tubular heat shield and an interior wall of the probe body; a temperature sensor positioned within the first annulus; a heating element positioned within the second annulus; a notched intake port positioned at a distal end of the probe body, wherein the probe body provides a conductive thermal path from the heating element to the notched intake port, the notched intake port including an open channel extending inward from a first face of the distal end into an intake aperture of the probe body opening to both the first annulus and the second annulus, and a cutaway region that defines a recessed second face inset from the first face and exposes the open channel at least partially from the leading edge; a weep hole penetrating from a base of the notched intake port to the trailing edge of the probe body; and wherein the notched intake port further comprises a slot inset from the recessed second face that traverses across at least a portion of the intake aperture perpendicularly to the open channel.
