An adjustable aerodynamic assembly includes a support structure and a blocking member supported by the support structure. The blocking member is movable between an extended position in which the blocking member is disposed transverse to the support structure to interact with an airflow and a retracted position in which the blocking member retracts to minimize interaction with the airflow. The adjustable aerodynamic assembly also includes an actuator coupled to the blocking member and configured to move the blocking member to the extended and retracted positions, and a detection member coupled to the blocking member and configured to determine whether a surface of the blocking member is detected. A method of monitoring the adjustable aerodynamic assembly includes determining whether the surface of the blocking member is detected via the detection member. The method also includes selectively activating the actuator to move the blocking member to the extended and retracted positions.
