INFRARED SENSORS
1. DESCRIPTION
That portion of the system that uses heat sensing devices such as infra-red scanners, infra-red image and
detection to acquire information. This includes the Enhanced Vision System.
The Enhanced Vision System (EVS) is an electro-optical system that uses a Long-Wave Infrared (IR) cam-
era to enhance situational awareness. Infrared red is particularly effective at night, smoke, haze, and smog
in addition to a broad spectrum of rain, snow, and radiation-type fog. EVS is an aid to visual acquisitions of:
• Ground vehicles and other ground-based equipment/obstacles,
• Aircraft on taxi-ways and runways,
• Other traffic during takeoff, approach, and landing,
• Runway and taxi lights,
• Runway and terrain features during climb, descent, and low altitude maneuvering.
The EVS sensor, located on the underside of the LH wing, contains a long-wave infrared camera that pro-
duces a infrared image and a low-light CMOS camera that produces a visible image. The two images are
then combined to produce a single monochrome image that is transmitted directly to the MFD. Upon
power-up the sensor requires approximately 90 seconds to produce a usable image.
28 VDC for Enhanced Vision System operation is supplied through the 5-amp EVS CAMERA circuit
breaker on Main Bus 3. Refer to the manufacturer’s approved Instructions For Continued Airworthiness.

2. TROUBLESHOOTING
Trouble - PFD Probable Cause Remedy
Video image not displayed. Software not configured. Perform Adjustment/Test - Per-
spective Integrated Avionics Sys-
tem Software Setup, selecting the
EVS option. (Refer to 42-20)
No power to EVS unit. Following initial power-up, listen
for series of clicks as camera
shutters open and close. If cam-
era doesn’t power on, verify secu-
rity of connectors and wire
harness.
Display not receiving image infor-
mation.
Verify security of connectors and
wire harness.
Halo Images. As sensor windows are heated,
infrared detector not able to com-
pensate for signal from window, as
compared to outside view, so a
white (hot) area may appear
around image perimeter.
Turn system on during preflight or
run-up to stabilize window and
body heaters prior to flight and
allow thermal stabilization.
Image degraded, or possibly even
displayed as solid black or solid
white.
Improper display settings. Following initial power-up, adjust
brightness and contrast settings
to obtain the best image.
Display is visible but has an X and
some bars through the image.
Anti-Tamper device not connected
properly.
Verify anti-tamper device is con-
nected to the proper pin.
Faulty wiring. Check wiring connecting anti-tam-
per device.
