An unmanned aerial vehicle application server (UAV-AS) acting as a superior UAV-AS for determining a flight policy to be applied to an unmanned aerial vehicle (UAV); wherein a plurality of UAV-AS are arranged in a hierarchical structure comprising a subordinate layer and at least one superior layer; the subordinate layer comprising a plurality of UAV-AS acting as subordinate UAV-AS in different geographical areas; the superior layer comprising one or more UAV-AS acting as superior UAV-AS; wherein each subordinate UAV-AS is tied to one superior UAV-AS; the superior UAV-AS comprising:
processing circuitry;
memory containing instructions executable by the processing circuitry whereby the superior UAV-AS is operative to:
receive a request from a subordinate UAV-AS, wherein the request comprises an indication of a geographical service area the subordinate UAV-AS is maintaining a flight policy for;
determine a list of subordinate UAV-AS that are tied to geographical service areas that are neighboring to the received geographical service area; and
returning the determined list of subordinate UAV-AS to the requesting subordinate UAV-AS, thereby enabling the requesting subordinate UAV-AS to query a flight policy from any of the subordinate UAV-AS on the list.
