Abstract: Embodiments of the inventive concepts disclosed herein may provide visual and audible flight direction cues to the pilot of a helicopter to maintain an optimum energy sustaining profile to successfully perform an autorotation maneuver. From the moment the engine fails or fails to provide adequate power to the main rotor system, systems described herein provide airspeed, attitude, and altitude guidance to the pilot to intercept and fly the correct path for a successful autorotation entry and autorotation descent. The system displays specific cues as the helicopter approaches the determined flare altitude and guides the pilot through the autorotation flare and minimum rate of descent touchdown.

Abstract: A present novel and non-trivial system, device, and method for generating surface information presentable on a display unit is disclosed, where the surface information may be presented to draw a viewer's attention to threatening terrain location within a targeted area. An image generator (“IG”) may be configured to receive navigation data; receive search data representative of at least a reference location, a targeted area, and a pattern comprised of a plurality of ground tracks; retrieve object data representative of object cell elevations of the targeted area; determine threat data representative of a threat level for each object cell; and generate an image data set representative of an image comprised of one or more threat-based search area location highlighters and/or one or more threat-based ground track location highlighters. The reference location could be comprised of a search pattern datum or a commencement search point.
