EFVS Value Proposition

• Enhanced Flight Vision System (EFVS)– EVS image displayed conformal head up

• Lower taxi / landing / takeoff operating minima

– Fewer go arounds

– Lower fuel costs



– Lower fuel costs

– Fewer delays/cancellations

– Increased loyalty/revenue

• Seeing in low visibility / darkness

– Fewer runway incursions

– Collision avoidance

EFVS Lower Minimums in EuropeEU OPS 1 Amendment 2

• Pilot using EFVS may continue to 100’ if a visual reference is displayed by the system

• AT 100’ requires natural view of visual references

• Controlling RVR is reduced by

Enhanced Flight Vision System (EFVS) Today

• Technical Solution Today: Extended mid-IR Camera systems– Operates in the ~1 to 5 micron band (cooled InSb cameras)

• Two EVS sensor suppliers: Kollsman and CMC

• Today’s Sensors meet certification requirements

– Displayed Head-Up

– Can Detect “airport environment” above 200’ in many



– Can Detect “airport environment” above 200’ in many environments

– Adequate latency and resolution

• Issues with Today’s Sensors

– Not sensitive to evolving LED-based airfield lighting systems

– Reliability

– Size and Weight

– Cost

ROCKWELL COLLINS APPROACH

Rockwell Collins EVS-3000

• Entry into service in 2015

– Embraer Legacy 450 / 500

• Multi-spectral technology

– High resolution image across broader spectrum

– Includes LED detection necessary for lower operating minima



• Uncooled sensor

– Higher reliability

– Lower size, weight and power

– Lower cost than current generation EVS for credit

• Availability on additional aircraft expected after initial EIS

SYNTHETIC VISION SYSTEMS



Head-up Synthetic Vision System (SVS)

Innsbruck Approach• Computer generated real time view of the

world from a pilot’s perspective based on terrain, runway, and obstacle databases

• Enhances awareness of the aircraft’s position relative to the runway and surrounding terrain

• Three discrete database “layers”

• Certified on BA Global Express

• SVS for lower landing credit (150’ DH,

COMBINED VISION SYSTEMS



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



� 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
