Moving Paddle Probe

Fitted to the side of the fuselage and consists of a moving probe with two slots open to the airflow connected to an enclosed paddle. Air pressure from the two slots is fed either side of the paddle. When the angle of attack increases so the dynamic pressure in the bottom slot increases and in the top slot reduces. This difference in the pressures will act either side of the paddle >to bring it into line with the airflow< -- keeping it in line with the airflow irrespective of the pitch angle of the aircraft (within reason).
