The invention relates to a method and system for supporting pilots in landing helicopters in visual flight under brownout or whiteout conditions. According to the invention, 3D data of the planned landing site are generated during the approach for landing, and are accumulated into a 3D representation of the landing site with the aid of position and attitude data of the helicopter. From this 3D representation, a virtual external view is continuously generated corresponding to the perspective of the actual position and attitude of the helicopter and is displayed for the pilot. A control routine ensures that no 3D data of the planned landing site that are generated under brownout or whiteout conditions are taken into account in the accumulation of the 3D representation.
