Abstract: The technology relates to aerial vehicle launch and land site selection. A method for determining beneficial launch and land sites may include computing a launch delay for a desired time period for each cell in a grid map with a target zone and an existing site located on the grid map, computing a flight time to target for a delay time that accounts for a launch delay, computing a launch time to target based on the launch delay and the flight time to target, receiving geographical restrictions data, and determining an efficiency benefit over the existing site based on the geographical restrictions data and a comparison of the launch time to target of each cell with the launch time to target of the existing site for the desired time period.

Abstract: The technology relates to generating a flight map for an aircraft. For instance, this may include, running a plurality of simulations by placing a simulated aircraft within each cell of a grid representing areas of the earth and using predicted wind data. Each simulations identifies a cell in which each aircraft is located at the end of the simulation. A connection graph may be generated using any identified cells. The connection graph may be used to determine a flight map for an actual aircraft using a cost function and iterating from a destination cell to an initial cell. The flight map may be used to determine a route for the actual aircraft. In some examples, the flight map may be refined by running further simulations. The refined flight map may then be used to determine a route for the actual aircraft.
