A device can receive information that identifies an airspace voxel that represents a three-dimensional portion of airspace during a particular time period. The device can associate one or more airspace parameters with the airspace voxel. The one or more airspace parameters can represent one or more conditions that relate to flight through the airspace voxel during the particular time period. The device can receive one or more flight parameters regarding a potential flight plan of an aircraft through a plurality of airspace voxels, including the airspace voxel, during the particular time period. The device can analyze the one or more flight parameters and a plurality of airspace parameters, associated with the plurality of airspace voxels, using one or more airspace rules. The device can output a recommendation regarding the potential flight plan based on analyzing the one or more flight parameters and the plurality of airspace parameters.
