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.

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.
