Abstract
A method and device provide a rotorcraft operator with real-time information concerning acoustic radiation on a region of the ground in the vicinity of the rotorcraft. A noise radiation model and at least one measured flight variable determine a high noise region on the ground that is bounded by a predefined noise level threshold. The method/device may include a display showing the high noise region and the position of the rotorcraft on a map. The rotorcraft operator may also be provided with real-time Blade-Vortex Interaction ('BVI') avoidance guidance while the rotorcraft is in flight.
