Abstract
A method of determining a trajectory for a rotorcraft, comprising: receiving an initial trajectory defining a planned flight path of the rotorcraft between a starting point and a target point; performing iterations of a loop comprising adding the initial trajectory to a set of selectable trajectories, evaluating a noise indicator of the rotorcraft for the initial trajectory on the basis of a noise-related acoustic footprint and a noise exposure level-related acoustic footprint, adding the evaluated noise indicator to a set of evaluated noise indicators, determining an alternative trajectory defining an alternative flight path of the rotorcraft between the starting point and the target point on the basis of the evaluated noise indicator, and setting the alternative trajectory as initial trajectory; and outputting a trajectory of the set of selectable trajectories associated with a selected noise indicator fulfilling predetermined noise indicator conditions.
