Central Air Data Computer

A Central Air Data Computer computes altitude, vertical speed, air speed, and mach number from sensor inputs such as pitot and static pressure and temperature. Early CADC systems were electromechanical computers, such as in the F-111. From 1968 to 1970, the first digital CADC was developed for the F-14. In the 1980s, the Standard Central Air Data Computer (SCADC) was developed to retrofit USAF and USN aircraft.
