Methods, systems, and apparatus, including computer programs encoded on computer storage media, for unmanned aerial vehicle authorization and geofence envelope determination. One of the methods includes determining, by an electronic system in an Unmanned Aerial Vehicle (UAV), an estimated fuel remaining in the UAV. An estimated fuel consumption of the UAV is determined. Estimated information associated with wind affecting the UAV is determined using information obtained from sensors included in the UAV. Estimated flights times remaining for a current path, and one or more alternative flight paths, are determined using the determined estimated fuel remaining, determined estimated fuel consumption, determined information associated wind, and information describing each flight path. In response to the electronic system determining that the estimated fuel remaining, after completion of the current flight path, would be below a first threshold, an alternative flight path is selected.

An Unmanned Aerial Vehicle (UAV) system, comprising: one or more sensor interfaces; anda computing system comprising one or more computing devices, said computing system programmed to implement: an estimator engine, the estimator engine configured to: determine an estimated fuel remaining in the UAV;determine an estimated fuel consumption of the UAV;determine, using information obtained via the one or more sensor interfaces from sensors included in the UAV, estimated information associated with wind affecting the UAV that indicates a direction of the wind;determine estimated flight times remaining for a current flight path that includes a plurality of waypoints, and one or more alternative flight paths that each include one or more of the plurality of waypoints, wherein determining an estimated flight time, for each of the current and alternative flight paths, uses: the determined estimated fuel remaining,the determined estimated fuel consumption,the information associated with wind, and information describing the current and alternative flight paths; andin response to determining that the estimated fuel remaining, after completion of the current flight path, would be below a threshold, select an alternative flight path that excludes one or more of the plurality of waypoints in a direction of travel substantially against the direction of the wind based on: a hierarchy of the waypoints included in the current flight path,the determined estimated fuel remaining, the determined estimated fuel consumption, andthe information associated with wind. 2. The system of claim 1, wherein the system is further configured to: obtaining information identifying one or more waypoints included in the current flight path but excluded in the selected alternative flight path; andproviding, to a remote system associated with an operator and for presentation by the remote system, information identifying the excluded waypoints. 3. The system of claim 1, wherein the system is further configured to: transmit, over the air the selected alternative flight path to a cloud system for approval, wherein the cloud system maintains flight path information associated with a plurality of UAVs. 4. The system of claim 3, wherein the system is further configured to: receive approval from the cloud system identifying a geofence envelope associated with the selected alternative flight path. 5. The system of claim 1, wherein the system is further configured to: determine the one or more alternative flight paths to each include at least one of the waypoints in the current flight path that corresponds to a return landing location of the UAV in the current flight path. 6. The system of claim 1, wherein information describing a particular flight path in the current and alternative flight paths includes respective associated topological information. 7. A method implemented by an Unmanned Aerial Vehicle (UAV) in flight, the UAV comprising an electronic system comprising hardware, the method comprising: determining, by the UAV electronic system, an estimated fuel remaining in the UAV;determining, by the UAV electronic system, an estimated fuel consumption of the UAV;determining by the UAV electronic system, using information obtained from sensors included in the UAV, estimated information associated with wind affecting the UAV that indicates a direction of the wind;determine estimated flight times remaining for a current flight path that includes a plurality of waypoints, and one or more alternative flight paths that each include one or more of the plurality of waypoints, wherein determining an estimated flight time, for each of the current and alternative flight paths, uses: the determined estimated fuel remaining,the determined estimated fuel consumption,the information associated with wind, andinformation describing the current and alternative flight paths; andin response to determining that the estimated fuel remaining, after completion of the current flight path, would be below a first threshold, selecting an alternative flight path that excludes one or more of the plurality of waypoints in a direction of travel substantially against the direction of the wind based on: a hierarchy of the waypoints included in the current flight path,the determined estimated fuel remaining, the determined estimated fuel consumption, andthe information associated with wind. 8. The method of claim 7, further comprising: transmitting, by the UAV to a remote system associated with an operator, information identifying the selected alternative flight path. 9. The method of claim 8, further comprising: obtaining information identifying one or more waypoints included in the current flight path but excluded in the selected alternative flight path; andproviding, to the remote system associated with the operator and for presentation by the remote system, information identifying the excluded waypoints. 10.
