The new SAE5-35 has given sight to the blind encoder by combining Mode C encoding with an Altitude Inflight Monitor (AIM) and multiple RS-232 outputs for GPS and terrain awareness systems. The AIM function keeps a constant eye on the pilot’s selected cruise altitude and advises any altitude deviation of 100 ft. Certified to 35,000 feet, the SAE5-35 provides transponder Grey code output and two RS-232 digital outputs in a single unit eliminating the need for any other special adapters or serializers.
