Building on the tradition of the AT150 – the workhorse ATC transponder of the industry - NARCO proudly introduces the ALL NEW AT165. Exciting features such as our one- touch code entry knob, multiple timers with alarm output, and altitude display with visual and audible altitude hold warning make the AT165 the pilot’s choice for the modern avionics panel. Our innovative dual independent displays with single button data exchange will always give the pilot the ability to fly confidently in the unlikely event of a display problem. The AT165 is both a receiver and a 250W transmitter which responds automatically to ground based radar interrogation. When interrogated, the squawk code and the pressure altitude of the aircraft are displayed on the ATC radar screen. Audible alerts from the AT165 warn the pilot when flying outside of the desired altitude range.
