EVS and SVS: The future of your PFD?

Honeywell's new blended-vision technology changes the way we look at weather and darkness. This technology will save lives. One of them might be yours.

Honeywell's SmartView flight display combines two vision enhancement tech-nologies, synthetic vision and enhanced vision, to create a display that gives pilots an unprecedented ability to see the runway through dark night conditions and even some weather. In this simulated screen capture, which shows the airplane on short final to Runway 21L at Prescott, Arizona, the EVS display is located in the center of the PFD, allowing the pilot to see what is really at the airport in real time. Note the approach lights are clearly visible. SmartView dims some PFD features in the landing area in order to allow a better view of the runway.
I took this photograph while on short final to Runway 21L at Prescott. Note the slight offset between the synthetic vision and the EVS, the latter of which shows what's really out there. In this case, if you landed on the centerline as displayed by the SVS, you'd be only about three feet off the mark.
When on the ground, the EVS expands in the field of view, allowing the pilot to get the big picture of what is really out there. On very dark nights, it could help prevent collisions with wildlife or other unseen obstructions.
In this shot of the PFD with only synthetic vision displayed (so, no EVS), you can see just how much less sense of texture and scale is conveyed despite the sophisticated texturing and shading effects that Honeywell employs.
With EVS displayed coming up on the airport at Prescott at night, this display shows just how effective EVS is at improving the sense of position and altitude. Note, too, how closely aligned the EVS and SVS images are.
