    Abstract: A system can include a flight controller for an aircraft that includes an electric motor that drives blades with a variable pitch, where the flight controller receives a command to change a flight characteristic of the aircraft and creates a torque command and a revolutions per minute (RPM) command. The system can also include a propulsion assembly, where the propulsion assembly creates a current command based at least in part on the torque command and the RPM command, creates a blade pitch command based at least in part on the torque command and the RPM command, communicates the current command to the electric motor to change a mechanical output of the electric motor, and communicates the blade pitch command to blade actuators to control the pitch of the blades. The current command and the blade pitch command cause the blades of the aircraft to rotate at a predetermined RPM.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for adjusting the transmission power of an unmanned aerial vehicle are disclosed. In one aspect, a method includes the actions of determining, by an unmanned aerial vehicle that includes a radio transceiver, an altitude of the unmanned aerial vehicle and a distance between the unmanned aerial vehicle and a base station. The actions further include, based on the altitude of the unmanned aerial vehicle and the distance between the unmanned aerial vehicle and the base station, determining, by an unmanned aerial vehicle, a transmission power level for the radio transceiver. The actions further include communicating, by the unmanned aerial vehicle, with the base station using the radio transceiver operating at the transmission power level.

    Abstract: A system, method, node, and computer program for determining a flight start policy to be applied to an unmanned aerial vehicle, UAV, (10) is described. The UAV (10) is associated with a first UAV-Application Server, UAV-AS (100) maintaining a flight policy applicable for the geographical service area (150) where the UAV (10) is located. The method comprising the first UAV-AS (100) determining whether the UAV (10) is going to leave the geographical service area (150) towards a second geographical service area (150), wherein the second geographical service area (150) is associated with a second UAV-AS (130). If so querying by the first UAV-AS (100) a flight policy applicable for the second geographical service area (150) from the second UAV-AS (130), and instructing a received flight policy applicable for the second geographical service to the UAV (10), before the UAV (10) has entered the second geographical service area (150).
