A 4D-trajectory algorithm is presented for optimized planning including operational constraints, e.g. threats. Another algorithm provides short term avoidance of unknown obstacles during a pre-planned mission. First qualitative assessments showed, that itīs well appropriate to leave and realign the planned track smoothly without jumping of the guidance aids.
