A system for enhanced display of obstacles in a combined vision display, the system comprising: a display unit; an enhanced vision system configured to generate first signals representative of enhanced vision images; a data storage device containing obstacle data representative of obstacles; a processor configured to select, or to receive from an operator of the vehicle a selection of one or more of the obstacles contained within the obstacle data to be overlaid in front of the enhanced vision images based on at least one of a size of the obstacle and a type of the obstacle; and a synthetic vision system configured to selectively retrieve obstacle data from the data storage device and generate second signals representative of synthetic vision images of the selected one or more obstacles, characterized in that the processor is in operable communication with the display unit and coupled to receive the first and second signals (26, 30) and is further configured, in response thereto, to: render enhanced vision images based on the first signals; render synthetic vision images of the selected one or more obstacles based on the second signals; selectively overlay the synthetic vision images of the one or more obstacles over the enhanced vision images; command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles, in a portion of a synthetic vision image associated with the combined vision display; and command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles overlaid over the enhanced vision images, the enhanced vision images overlying a portion of an underlying synthetic vision image in a portion of an enhanced vision image of the combined vision display such that the selected one or more obstacles are displayed in both the portion of the enhanced vision image and the portion of the synthetic vision image. a display unit; an enhanced vision system configured to generate first signals representative of enhanced vision images; a data storage device containing obstacle data representative of obstacles; a processor configured to select, or to receive from an operator of the vehicle a selection of one or more of the obstacles contained within the obstacle data to be overlaid in front of the enhanced vision images based on at least one of a size of the obstacle and a type of the obstacle; and a synthetic vision system configured to selectively retrieve obstacle data from the data storage device and generate second signals representative of synthetic vision images of the selected one or more obstacles, characterized in that the processor is in operable communication with the display unit and coupled to receive the first and second signals (26, 30) and is further configured, in response thereto, to: render enhanced vision images based on the first signals; render synthetic vision images of the selected one or more obstacles based on the second signals; selectively overlay the synthetic vision images of the one or more obstacles over the enhanced vision images; command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles, in a portion of a synthetic vision image associated with the combined vision display; and command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles overlaid over the enhanced vision images, the enhanced vision images overlying a portion of an underlying synthetic vision image in a portion of an enhanced vision image of the combined vision display such that the selected one or more obstacles are displayed in both the portion of the enhanced vision image and the portion of the synthetic vision image. render enhanced vision images based on the first signals; render synthetic vision images of the selected one or more obstacles based on the second signals; selectively overlay the synthetic vision images of the one or more obstacles over the enhanced vision images; command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles, in a portion of a synthetic vision image associated with the combined vision display; and command the display unit such that the combined vision display displays the synthetic vision images of the selected one or more obstacles overlaid over the enhanced vision images, the enhanced vision images overlying a portion of an underlying synthetic vision image in a portion of an enhanced vision image of the combined vision display such that the selected one or more obstacles are displayed in both the portion of the enhanced vision image and the portion of the synthetic vision image.
