The selection of the features may be predetermined, made by the pilot, or based on the operational status of the aircraft. ## Claims ### Claim 1 A display system for displaying images, comprising: an enhanced vision system configured to generate a stream of enhanced vision images, each enhanced vision image comprising a plurality of enhanced features; a synthetic vision system database configured to generate a stream of synthetic vision images, each synthetic vision image comprising a plurality of synthetic features; a processor coupled to the enhanced vision system and the synthetic vision system and configured to: select a portion of the synthetic features; and align the portion of selected synthetic features and the enhanced vision images; and a display coupled to the processor and configured to display the aligned enhanced vision images and the selected synthetic features. ### Claim 2 (depends on 1) The display system of claim 1 further comprising selecting a first format for the selected synthetic features, and a second format for the SVS features within the enhanced vision image. ### Claim 3 (depends on 2) The display system of claim 2 wherein the changing step comprises changing the first format includes changing one of the formats selected from the group consisting of intensity, color, transparency, or shape. ### Claim 4 An aircraft display system for displaying images to an aircrew of an aircraft, comprising: an enhanced vision system configured to generate enhanced vision images; a synthetic vision database containing information regarding lighting for a landing approach path of the aircraft; a synthetic vision system configured to obtain information from the synthetic vision database for generating synthetic vision images of the lighting based on flight conditions of the aircraft; a processor coupled to the enhanced vision system and the synthetic vision system and configured to: select a portion of the synthetic features; and a display configured to display the enhanced vision images and the selected portion of the synthetic images. ### Claim 5 (depends on 4) The aircraft display system of claim 4, wherein the processor is further configured to select the synthetic features in response to an input from the aircrew. ### Claim 6 (depends on 4) The aircraft display system of claim 4, wherein the processor is further configured to select the synthetic features in response to the operational status of the aircraft. ### Claim 7 (depends on 4) The aircraft display system of claim 4, wherein the processor is further configured to select the synthetic features in response to predetermined factors. ### Claim 8 (depends on 4) The aircraft display system of claim 4 wherein the processor is further configured to change the format of the synthetic features in consideration of the format of the enhanced features. ### Claim 9 (depends on 8) The aircraft display system of claim 8 wherein the processor is further configured to change at least one of the formats selected from the group consisting of color, transparency, or shape. ### Claim 10 (depends on 4) The aircraft display system of claim 4 wherein the processor is further configured to select a plurality of grid lines. ### Claim 11 (depends on 4) The aircraft display system of claim 4 wherein the processor is further configured to select one of the objects selected from the group consisting of terrain features, obstacles, a target of interest, or geographic data. ### Claim 12 A method for displaying images to an aircrew member of an aircraft, comprising: generating enhanced vision system images, each comprising a plurality of enhanced features; generating synthetic vision system images, each comprising a plurality of synthetic features; selecting a portion of the synthetic features; and displaying the enhanced vision system images and the selected portion of the synthetic features. ### Claim 13 (depends on 12) The method of claim 12 wherein the selecting step comprises: selecting the portion of the synthetic features by the aircrew member. ### Claim 14 (depends on 12) The method of claim 12 wherein the selecting step comprises: selecting the portion of the synthetic features in accordance with the operational status of the aircraft and preselected features. ### Claim 15 (depends on 12) The method of claim 12 further comprising: changing the format for at least some of the selected portion of the synthetic features corresponding to the enhanced features being displayed. ### Claim 16 (depends on 15) The method of claim 15 wherein the changing step comprises changing at least one of the color, transparency, or shape. ### Claim 17 (depends on 12) The method of claim 12 wherein the selected portion of the synthetic features comprises: a plurality of grid lines. ### Claim 18 (depends on 12) The method of claim 12 wherein the selected portion of the synthetic features comprises: a plurality of terrain and obstacle features. ### Claim 19 (depends on 12) The method of claim 12 wherein the selected portion of the synthetic features comprises: a target of interest comprising data stored in the database or uploaded from a datalink. ### Claim 20 (depends on 12) The method of claim 12 further comprising: determining if one of the enhanced features corresponding to one of the selected synthetic features satisfies a threshold; and omitting the display of the selected synthetic feature corresponding to the enhanced feature satisfying the threshold.
