Aircraft flight deck displays and systems and methods for enhanced display of obstacles in a combined vision display

Systems and methods for enhanced display of obstacles in a combined vision display are provided. The system comprises a display unit and an enhanced vision system configured to generate first signals representative of enhanced vision images. Data storage device contains obstacle data representative of obstacles. Synthetic vision system is configured to selectively retrieve obstacle data from data storage device and generate second signals representative of synthetic vision images of one or more obstacles. Processor is in operable communication with display unit and coupled to receive first and second signals and configured, in response thereto, to: overlay the synthetic vision images of the one or more obstacles over the enhanced vision images and command display unit to display the synthetic vision images of the one or more obstacles overlaid over the enhanced vision images. The overlaid synthetic vision images of the one or more obstacles may be visually highlighted.
