A node (121-123) of a wireless communications network (120) and an aerial vehicle (110), such as an Unmanned Aerial Vehicle (UAV), a drone, an aircraft, or a helicopter, comprising a communications module (111) are provided. The node is operative, in response to detecting that the aerial vehicle enters a pre-defined geographical region (221-227) within a coverage area of the wireless communications network, to transmit a cell broadcast message (126; 201-204) to the aerial vehicle. The aerial vehicle is operative to receive the cell broadcast message from an access node (121) of the wireless communications network, and, in response thereto, correct its flight path (211-214) based on the received cell broadcast message. Preferably, the cell broadcast message comprises at least one, or a combination, of an instruction, a limitation, a restriction, a direction or a change thereof, a bearing or a change thereof, an altitude or a change thereof, an aerial vehicle type, and an aerial vehicle identity.
