Abstract

An angle of attack sensor (10) has a rotating vane (16) that is sensitive to airflow direction mounted on a shaft (18) that in turn is rotatably mounted on a housing (22). The housing (22) is supported on an aircraft (14), and includes a non contact magnetic sensing assembly (23) for sensing the rotation of the shaft (18) relative to the housing (22). The sensor assembly (23) includes a magnet (28) that mounts on the shaft (18), and a magnetoresistive (MR) sensor (32) that mounts on the housing (22) in a position so that as the shaft (18) rotates the magnetic field from the magnet (28) changes, and this change in magnetic field is sensed and provided as an indication of angle of attack change.
