Digital Air Data Computer

The HG180E1 digital air data computer is designed as a high-reliability DADC for the 737-300, -400 and –500. The design uses the ARINC 706s high MTBF (more than 22,000 flight hours), sensor technology and B42 design thus assuring interchangeability on 737 aircraft, and use of existing test equipment. Two cards are incorporated for additional analog outputs required for the 737-700 application. It contains extensive BIT, which provides both power-up and continuous in-flight fault detection capability. The presence of SSEC increases performance and interchangeability.
