Dual threaded system for low visibility operations
First Claim
1. A system for controlling an image displayed on a display unit of an aircraft, the system comprising:
- an enhanced vision system that detects elements of an approach lighting system for display on the display unit;
a synthetic vision system that uses a database of navigation information and a determined aircraft location to generate synthetic display elements representing the approach lighting system;
display electronics that cause the detected elements from the enhanced vision system to be simultaneously displayed on the display unit within a same scene as the generated synthetic display elements from the synthetic vision system, whereby the simultaneous display allows a pilot viewing the display unit to check for whether information provided by the enhanced vision system matches information provided by the synthetic vision system, wherein positions of the synthetic vision system elements and an enhanced vision system scene are independently derived such that neither the enhanced vision system scene nor the generated synthetic vision system elements are adjusted in response to information from the other system and neither are adjusted in response to information from a shared source.

Abstract
A system for controlling an image displayed on a display unit of an aircraft is shown and described. The system includes an enhanced vision system that detects elements of an approach lighting system for display on the display unit. The system also includes a synthetic vision system that uses a database of navigation information and a determined aircraft location to generate synthetic display elements representing the approach lighting system. Display electronics of the system cause the detected elements from the enhanced vision system to be simultaneously displayed on the display unit within a same scene as the generated synthetic display elements from the synthetic vision system. Advantageously, the simultaneous display allows a pilot viewing the display unit to check for whether information provided by the enhanced vision system matches information provided by the synthetic vision system.

16. A method for controlling an image displayed on a display unit of an aircraft, comprising:
-
using an enhanced vision system to detect elements of an approach lighting system for display on a scene of a display unit; using a synthetic vision system and the synthetic vision system'"'"'s database of navigation information to generate synthetic display elements representing the approach lighting system; and causing the detected elements from the enhanced vision system to be simultaneously displayed on the display unit within the same scene as the generated synthetic display elements from the synthetic vision system, wherein positions of the synthetic vision system elements and an enhanced vision system scene are independently derived such that neither the enhanced vision system scene nor the generated synthetic vision system elements are adjusted in response to information from the other system and neither are adjusted in response to information from a shared source. - View Dependent Claims (17, 18)

19. Non-transitory computer-readable media comprising computer executable instructions for completing the following steps:
-
using an enhanced vision system to detect elements of an approach lighting system for display on a scene of a display unit; using a synthetic vision system and the synthetic vision system'"'"'s database of navigation information to generate synthetic display elements representing the approach lighting system; and causing the detected elements from the enhanced vision system to be simultaneously displayed on the display unit within the same scene as the generated synthetic display elements from the synthetic vision system, wherein positions of the synthetic vision system elements and an enhanced vision system scene are independently derived such that neither the enhanced vision system scene nor the generated synthetic vision system elements are adjusted in response to information from the other system and neither are adjusted in response to information from a shared source.
