L-3 Communications subsidiary L-3 Avionics Systems received supplemental type certification (STC) and Parts Manufacturer Approval (PMA) for the IRIS infrared imaging system aboard the King Air C-90. L-3 said the IRIS system displays a real-time, gray scale image of the runway environment, other aircraft, terrain, people, animals and obstacles on a cockpit display. At night and during poor visibility conditions, IRIS helps pilots see obstacles that are invisible to the naked eye. During the day, pilots can see obstacles otherwise obscured by bright oncoming light or solar glare. The current STC covers IRIS imagery displayed on the Bendix/King KMD 850 multifunction display. L-3 said it is actively pursuing additional display options. For related news
