Abstract: Method for autonomous safe emergency landing of a powered unmanned aerial vehicle (UAV) in the event of an engine failure. A landing approach trajectory is generated, including a downwind leg, initiating at an initiation point of the trajectory, an upwind leg, terminating at a selected touchdown point, and a U-turn leg, joining between the downwind leg and the upwind leg. The UAV is directed to the initiation point to follow the downwind leg. A glide ratio of the UAV is repeatedly determined based on current flight conditions. A current turning point is repeatedly determined along the downwind leg based on the determined glide ratio, the U-turn leg initiating at the current turning point. When the UAV arrives at the current turning point, the UAV is directed to follow the U-turn leg and the upwind leg, for landing the UAV at the selected touchdown point.

Abstract: A safety system for preventing aircraft collisions with objects on the ground is provided herein. The safety system may include gated imaging sensors attached to the aircraft that capture overlapping gated images which are images that allow estimating the range of the imaged objects. The overlap zones are utilized to generate a three dimensional model of the aircraft surroundings. Additionally, aircraft contour data and aircraft kinematic data are used to construct an expected swept volume of the aircraft which is then projected onto the three dimensional model of the aircraft surroundings to derive an estimation of likelihood of collision of the aircraft with objects in its surroundings and corresponding warnings.
