Abstract:
1. A method for calculating a flight route between a first position and a second position, wherein the first position is initially chosen as a current position, and wherein the following steps are repeated until the second position is reached: a loss function is determined corresponding to each flight path in a set of flight paths that are predefined in relation to a current direction of flight; a flight path that yields a most advantageous value for the loss function is selected; a subsection from the current position and a predetermined number of positions forward are registered for the selected flight path; a position at an end of the subsection is chosen as a new current position; wherein after the flight route has been calculated between the first and the second position, the calculated route is refined in a refining step, in which registered points that are located as far from one another as possible but between which unobstructed visibility prevails are marked as breakpoints, and in that the route is chosen as straight lines between these marked breakpoints.
