The lateral-directional flight control system schedules gains as a function of AOA and speed.[^1] Interconnects remove adverse roll and yaw.[^1] It only uses the lateral accelerometer for AOA below 16 degrees.[^1] At some angles of attack, control surfaces are completely removed from the system.[^1] State-space matrices for each flight condition were used for analysis.[^1] The lateral-directional axes are controlled using rudders, flaperons, ailerons and horizontal tails.[^1]
