Abstract: A present novel and non-trivial system, apparatus, and method for generating runway visual aids on an aircraft display unit. Visual aids could comprise of runway indicators corresponding to minimum and maximum rollout and touchdown points, each of which may be determined in real-time by applying input factors to one or more configurable landing profiles. Data representative of visual aids may be provided by one or more sources including runway data sources and real-time input factors. An image generating processor generates an image data set representative of a three-dimensional perspective view of a scene outside the aircraft, wherein the image data set is determined as a function of terrain data, runway data, and visual aid data. The image data set may be provided to a Head-Down Display unit, a Head-Up Display unit, or both, whereby an image contains a runway depicted with at least one visual aid.

Abstract: Present novel and non-trivial system, device, and method for combining image data received from two or more vision systems are disclosed. A system may be comprised of a first vision source, a second vision source, and an image generator (“IG”). The first vision source may be could configured to generate a first image data set and a depth buffer data set, and the second vision data source could configured to generate a second image data set. The IG could be configured to receive both the first and second image data sets; the depth buffer data set; and generate a third image data set as a function of both image data sets, the depth buffer data set, and a pixel cutoff distance that may be fixed or variable. In addition, the pixel cutoff distance may be determined as a function of input variable data.

Abstract: A present novel and non-trivial system, apparatus, and method for generating runway visual aids on an aircraft display unit, where such visual aids could be comprised of surface markings corresponding to the runway. Navigation data and runway data may be provided to an image generating processor which, in turn, generates an image data set representative of at least one visual aid corresponding to one runway located in the scene outside the aircraft. The intensity or brightness of a visual aid could vary when the aircraft is operating on the approach phase of flight. The variation of such intensity could be defined as a function of the navigation data and the data representative of one or more waypoints. The image data set may be provided to a Head-Down Display unit, a Head-Up Display unit, or both, each visual aid is presented on the screen of the display unit.

Abstract: A present novel and non-trivial system, apparatus, and method for generating HUD image data from synthetic image data is disclosed. Based on a multi-channel pixel intensity data set generated by a synthetic vision system, a single-channel pixel intensity data set representative of a lighted solid image of terrain comprised of a plurality of intensities of one color may be generated. The single-channel pixel intensity image data set may be determined as a function of multi-channel pixel intensity data set and channel weighting, where channel weighting may be based on sky and/or terrain colors employed by an SVS. Based on the multi-channel pixel intensity data set, a three-dimensional perspective scene outside the aircraft may be presented to the pilot on a HUD combiner. Also, the multi-channel pixel intensity data set may be modified by using at least one chroma key, where such chroma key may be assigned to a specific multi-channel pixel intensity value.

Abstract: A present novel and non-trivial system, module, and method for presenting NOTAM information are disclosed. A plurality of sources may be used for providing navigation data, terrain data, NOTAM data, and object data. After receiving this data, a NOTAM display generating processor may generate a NOTAM image data set as a function of the navigation data, terrain data, NOTAM data, and object data. The NOTAM image data set may be representative of NOTAM information presented in a three-dimensional perspective of a scene outside an aircraft, where NOTAM information may comprise non-textual NOTAM information, textual NOTAM information, or both. After being generated, the NOTAM image data set may be provided to a presentation system where NOTAM information may be presented on at least one tactical display unit such as a head-down display unit and/or a head-up display unit.

Abstract: The present disclosure is directed to a dynamic field of view (FOV) for a synthetic vision system (SVS) scene. The FOV within the SVS scene may switch between a FOV conformal to the real world outside of a vehicle and a wider FOV when beneficial. In an aircraft, for example, generating the SVS scene with the narrower FOV may be optimal during flight, while on the ground a wider FOV may improve situational awareness during taxiing. Determination of the airborne or grounded status of the aircraft may be based on speed, altitude, user input, or a received signal. Although the foregoing has been described within a particular context, the present disclosure is not limited to this scenario and may be applied to any vehicle in any situation where dynamically changing between a narrower FOV and a wider FOV is beneficial.

Abstract: A present novel and non-trivial system, apparatus, and method for presenting information to the pilot on an aircraft display unit employed in a synthetic vision system (“SVS”), an enhanced vision system (“EVS”), or combined system. Information regarding the locations of visible and invisible objects related to aviation such as airports, navigation aids and facilities, and airspace are provided by location markers. Data representative of the terrain and location of objects depicted in a scene outside the aircraft are retrieved from one or more data sources. An image generating processor generates an image data set representative of a three-dimensional perspective view of a scene outside the aircraft, wherein the image data set is determined as a function of the terrain data and location marker data associated with the location data. The image data set may be provided to a Head-Down Display unit, a Head-Up Display unit, or both.

Abstract: A present novel and non-trivial system, module, and method for presenting an abbreviated pathway on a tactical display unit. A processor generates an image data set representative of a pathway and a three-dimensional perspective scene outside the aircraft using terrain data, first location highlighter data, and second location highlighter data, where the first location highlighter data corresponds to the active flight path and second location highlighter data corresponds to a subsequent flight path. After being presented to a display system, an image represented in the image data set is presented on a tactical display unit, whereby an abbreviated pathway appears superimposed against the three-dimensional perspective scene outside the aircraft, where location highlighters are used for the depiction of the pathway comprising of at least one enhanced boundary of the active path, the second waypoint, the third waypoint, and the flight path formed between the second and third waypoints.
