13772-138 1 of 4 Cirrus Design Section 9 SR22 Supplements Pilot’s Operating Handbook and FAA Approved Airplane Flight Manual Supplement for Enhanced Vision System When the Enhanced Vision System is installed on the aircraft, this POH Supplement is applicable and must be inserted in the Supplements Section (Section 9) of the basic Pilot’s Operating Handbook. This document must be carried in the airplane at all times. Information in this supplement adds to, supersedes, or deletes information in the basic Pilot’s Operating Handbook. Original Issue: 07-29-08 2 of 4 13772-138 Section 9 Cirrus Design Supplements SR22 Section 1 - General No Change. 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 3 - Emergency Procedures No Change. Section 3A - Abnormal Procedures No Change. Section 4 - Normal Procedures No Change. Section 5 - Performance No Change. Section 6 - Weight & Balance Refer to Section 6 - Weight and Balance of the basic POH for current weight and balance data. Original Issue: 07-29-08 13772-138 3 of 4 Cirrus Design Section 9 SR22 Supplements 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 Original Issue: 07-29-08 4 of 4 13772-138 Section 9 Cirrus Design Supplements SR22 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. Original Issue: 07-29-08
