The Neal-Smith criterion for handling qualities analysis of highly augmented aircraft is rewritten in terms of H∞ norms. The pitch attitude control is solved in the framework of an H∞ problem by the model matching technique to yield H∞-control pilot models. The obtained H∞ closed-loop transfer function satisfies the Neal-Smith criterion quite well, and the required pilot compensation is clearly exhibited in the H∞-control pilot model. Surveying all the flight configurations in the work by Neal and Smith, an attempt is made at pursuing the pilot compensation indices that correlate well with pilot ratings.
