Unmanned aerial vehicle authorization and geofence envelope determination

A method implemented by an Unmanned Aerial Vehicle (UAV) in flight, the UAV comprising an electronic system comprising hardware, the method comprising:

• determining information associated with the UAV, including:
• estimated fuel remaining,
• estimated fuel consumption,
• information associated with wind affecting the UAV that indicates a direction of the wind;
• determining, using the monitored information, an estimated flight time remaining for a current flight path that includes a plurality of waypoints;
• and
• determining that the estimated fuel remaining, after the estimated flight time, would be below a threshold, and selecting one or more waypoints included in the current flight path to be excluded from the current flight path based, at least in part, on the direction of the wind.

A computer program product, encoded on one or more non-transitory computer storage media, comprising instructions that when executed by one or more processors included in an Unmanned Aerial Vehicle (UAV) cause the one or more processors to perform operations comprising:

• determining information associated with the UAV, including:
• estimated fuel remaining,
• estimated fuel consumption,
• information associated with wind affecting the UAV that indicates a direction of the wind;
• determining, using the monitored information, an estimated flight time remaining for a current flight path that includes a plurality of waypoints;
• and
• determining that the estimated fuel remaining, after the estimated flight time, would be below a threshold, and selecting one or more waypoints included in the current flight path to be excluded from the current flight path based, at least in part, on the direction of the wind.
