This paper presents a return-to-home function with a turn-around maneuver developed as a part of an automatic trajectory generation system, for an integrated flight guidance system. The trajectory generation system has been developed at the Institute of Flight System Dynamics as a modular and flexible platform that can be used for a broad range of systems. The turn-around maneuver presented in this paper is based on a 45◦/180◦ procedure turn, which is used to reverse the course of the aircraft, before flying the inverted flight plan in order to go back to the take-off point. The decision to invert the flight plan is motivated by the fact that the system is intended to be used in non-segregated airspace, where the aircraft might not be allowed to simply fly a straight line or an optimized path other than the uploaded flight plan. The paper presents both the development of the maneuver, and the integration logic in the trajectory generation system.     «
