A method is for detecting a blockage of a wind vane (12) of an aircraft, with the wind vane (12) including a support (20), a paddle (22) mounted rotating relative to the support (20) along an axis (A), a motor (28) able to exert a rotational torque on the paddle (22) along the axis (A), the motor (28) being connected to a processing unit (18). The method includes applying a predetermined blockage detection torque on the paddle (22) by the motor (28); measuring at least one piece of information representative of a resistance of the paddle (22) to the predetermined detection torque; and generating, via the processing unit (18), a blocking information signal, if a predetermined condition based on the representative information is verified.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for controlling spraying of chemicals by an unmanned aerial vehicle (UAV). An unmanned aerial vehicle system includes one or more processors configured to perform operations of autonomously performing a flight path by the UAV and dispersing a chemical by the UAV along portions of the flight path. The UAV may include a chemical spray system having one or more spray booms with multiple nozzles for dispersing a chemical. The chemical spray system may include one or more tanks attached to the body of the UAV and a pump fluidly connected to the tanks to disperse chemical via the spray booms.

An unmanned aircraft includes: a processor; and at least two generators that generate thrust for the unmanned aircraft to fly, the at least two generators each including a corresponding one of rotor blades that produce airflows. In the unmanned aircraft, the processor generates a control request for changing a rotational speed of at least one of the rotor blades of the at least two generators to reduce a difference between rotational speeds, in response to start of sound recording by a microphone, and the at least two generators rotate the rotor blades in accordance with the control request.

Example moveable mounting structures and methods are described. In one implementation, an unmanned aerial vehicle (UAV) includes a body and a moveable mounting structure coupled to the body. The moveable mounting structure can move between a stowed position and a deployed position without interfering with a payload carried by the UAV. A camera is mounted to the moveable mounting structure.
