Section 2 - Limitations
Enhanced Vision System
1. The Enhanced Vision System (EVS) cannot be used for flight
guidance, navigation, traffic avoidance, or terrain avoidance.
Maneuvering the airplane in any phase of flight such as taxi,
takeoff, approach, landing, or roll out shall not be predicated on
EVS imagery. The EVS shall only be used as an aide to assist the
flight crew to visually acquire objects normally viewed through the
cockpit windows.
2. The Max Viz Enhanced Vision System Information Manual, P/N
309100024 Revision 1 or later must be available to the pilot during
flight.

Section 7 - System Description
Max Viz Enhanced Vision System
The Enhanced Vision System is an electro-optical system that uses a
Long-Wave Infrared (IR) camera. Infrared is particularly effective at
night, smoke, haze, and smog in addition to a broad spectrum of rain,
snow, and radiation-type fog. However, penetration is limited during
certain environmental conditions associated with heavy rain, heavy
snow, coastal fog and most cloud formations. Therefore the EVS is not
intended for all atmospheric conditions and may only be used for
acquisition of objects normally viewed through the cockpit windows.
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 produces a infrared image and a lowlight
CMOS camera that produces a visible image. The two images are
then combined to produce a single fused image and transmitted
directly to the MFD. Upon power-up the Sensor requires approximately
90 seconds to produce a usable image. The image generated is a
monochrome image. The hotter an object is the whiter it appears on
the display.
28 VDC Enhanced Vision System operation is supplied through the 5-
amp EVS Camera circuit breaker on MAIN BUS 3.
Refer to the Perspective Integrated Avionics System Pilot’s Guide for a
general description of the system and its operating modes. Refer to
the Max Viz Enhanced Vision System Pilot’s Guide for a detailed
discussion of the system. For maintenance information and special
precautions to be followed, refer to Section 8, Ground Handling,
Servicing, and Maintenance

Section 8 - Maintenance
Enhanced Vision System Sensor Windows (Optional)
The Enhanced Vision System Sensor is located on the underside of
the LH wing. The three sensor windows are made of Germanium. In
contrast to visible light energy, infrared energy typically passes
through dirt on the window. As such, the Sensor windows requires
only occasional cleaning with mild liquid soap and water or isopropyl
alcohol, and a soft cloth.
• Caution •
If a EVS Sensor Window breaks, use gloves and masks when
handling broken germanium window material.
Do not use abrasive cleansers or cleaning pads on the
germanium window. Abrasive cleaning can damage the
sensor window coating.
Do not use any cleansers containing ammonia. Ammonia will
remove the sensor window coating.
