Innovative Solutions & Support (IS&S) received an STC for installation of a dual digital air data computer (DADC) system on Boeing 727-100s and -200s. The approval certifies the DADC components of the Malvern, Pa.-based supplier of cockpit data systems to the accuracy requirements for reduced vertical separation minimum (RVSM) operation and provides the needed approval for installation of IS&S RVSM-compliant equipment on these aircraft. In addition to the DADC, the RVSM retrofit includes two repeater altimeters and a common altitude alerter.
