Head Up Vision System – Combined Vision
SVGS is weather independent, but limited by accuracy of navigation solution and integrity of databases
– Independent monitoring solutions will enable SVGS approaches to 1400RVR / 150’ DA
EFVS performance weather dependent
– Sensor must image at Decision Altitude allowing the pilot to fly the Visual Segment from the standard DA/DH to 100’ HATh, or the runway (depending on EFVS I or II system)

HATh, or the runway (depending on EFVS I or II system)
• Combines the operational credits associated with EFVS and SVGS and seamlessly connects these technologies to increase operational reliability
– Adaptive Smart Fusion algorithm blends based on image detail
• HVS Technology Focus:
– Continued focus on best integration of technologies
– Drive subsystems to right cost/performance point
– Develop new technologies that increase operational benefits.
– Develop algorithms for image optimization minimizing clutter and ensuring system enhances natural visibility

Key Benefits of CVS
1. The fused image is better than the sum of its parts� Single HUD image contains key information from multiple sources
2. Reduced cockpit workload� Imagery is easily interpreted, more timely situational awareness
3. Information content highly adaptable to current operation� Take-off, climb and cruise, approach and landing, roll-out, taxi

Rockwell Collins Proprietary Information
� Take-off, climb and cruise, approach and landing, roll-out, taxi
� Automatic or manually tailored (pilot selectable modes?)
4. Improved system integrity and certifiability� Sensed and Synthetic streams are derived from independent and
dissimilar sources
� Comparisons lead to higher Design Assurance Level, and eventually to improved operational benefits
� Additional Landing Benefits
