Methods, systems, and devices are disclosed for providing control of an unmanned aircraft (UA). A server may receive an indication from a UA that a transition from autonomous flight to pilot controlled flight is required while the UA is in autonomous flight. The server may select a pilot station for providing pilot controlled flight of the UA. Selecting a pilot station for providing pilot controlled flight of the UA may be based on a pilot criterion associated with the pilot station. A UA may detect a condition that requires a transition from autonomous flight to pilot controlled flight and establish a pilot criterion for pilot controlled flight based on the detected condition. The UA may send a request for a pilot that includes the pilot criterion and information about the condition.
