An unmanned aerial vehicle (UAV) system, location and method, for operation with a flight management system, has a controlled access UAV zone for at least one of: UAV landing, UAV loading, and UAV take-off. A sensor can be in communication with a control panel and/or a lock to govern access to the UAV zone. The zone can have a barrier with closure secured by the lock, and controlled by a flight management system. Separate access codes can be provided for departure and destination locations, to enable personnel associated with a delivery request to access those locations, to effect delivery of an article. The codes can be generated and supplied when the flight management system receives a valid delivery request.
