Abstract
Abstract A method of aligning an aircraft fuselage axis with an air or ground targ while maintaining a predetermined flight path, involves turning the fuselage around the yaw axis and the transverse axis relative to the flight path. In performing the fuselage turn a side-slip angle is effected by vertical rudder control and superposed thereon is an oppositely directed roll angle. The actuation of the flight control for the fuselage turn is coupled with the fire control system of the aircraft.

Method of aligning an aircraft fuselage axis with an air or ground target while maintaining a predetermined flight path wherein the aircraft has a flight control system and a fire control system comprising turning the fuselage around the yaw axis and the transverse axis relative to the flight path by one of direct lateral force control and direct lifting control wherein the improvement comprises in carrying out the fuselage turn effecting a side-slip angle by vertical rudder control and superposing thereon an oppositely directed roll angle, and coupling the actuation of the flight control for the fuselage turn with the fire control system of the aircraft.
