Optimising airspace blocks comprises receiving initial spatial and temporal coordinates of initial airspace blocks AB1-AB8 within an airspace; receiving pairs of waypoints and obtaining an initial flight path between each pair, wherein each flight path complies with availability of the initial airspace blocks and has an associated objective variable; defining an initial total objective variable as the sum of those objective variables; iteratively modifying the spatial and temporal coordinates of the blocks and calculating corresponding compliant flight paths between the waypoints and associated objective variables which sum to a modified total objective variable; and outputting – as optimised airspace blocks - spatial and temporal coordinates of the blocks which reduce the modified total objective variable relative to the initial total objective variable. The flight paths may be optimised using Dijkstra’s or the Bellman-Ford algorithm, weather data or aircraft performance models. The objective variable may be flight time, emissions or cost. The airspace blocks may be military airspace restrictions, civil route closure, closed airspace or SIGMET.
