A repellence system and method for repelling animals includes an imaging device arranged to generate image data from a railway track, one or more deterrence devices arranged to carry out deterrence actions for repelling animals and a repellence sub-system having one or more processors and memory storing instructions for execution by the one or more processors. The repellence sub-system being configured to receive image data of the railway track from the imaging device, detect an animal in the image data, identify animal species of the detected animal in the image data, provide species specific deterrence instructions to the one or more deterrence devices based on the identified animal species.

During aircraft descent, flight control systems seek and maintain a glide slope determined from a single pilot input parameter; e.g., the position of a control axis of a flight stick. Appropriate guide slope selection by the pilot is readily determined from the pilot's visual observation of an intended landing site during landing approach. The glide slope defines a ratio of forward speed and descent speed which is automatically established and maintained/updated according to pilot input while these speeds are also automatically reduced during descent, despite the two speed directions respectively being affected distinctly and differently by aircraft mechanisms which control them. The aircraft ends its glide path with speed at or near zero, allowing landing by short vertical descent. Accordingly, the pilot offloads problems of both coordinating speeds to achieve a particular guide slope, and reducing them while maintaining this coordination.

A control method, device, aircraft, and storage medium for an aircraft are provided. The method includes: determining position information of the aircraft and position information of a load on a bearing surface; determining whether a horizontal position of the aircraft satisfies a first preset condition based on the position information of the aircraft and the position information of the load; in response to the horizontal position of the aircraft not satisfying the first preset condition, prohibiting the aircraft from pulling the load away from the bearing surface. In this way, the probability of the cable entangling the rotor blade during the process of the aircraft pulling the load away from the bearing surface, and the probability of the load pulling the aircraft and causing it to tip over, can be reduced, thereby ensuring the safety of the aircraft during takeoff.
