Rockwell Collins completed its acquisition of communications and systems integration specialist Arinc late on Monday. The avionics group, which paid The Carlyle Group $1.4 billion for Arinc, said that the integration of its new division should be complete within six to nine months. βWith this move we take a major leap forward to realizing our vision of providing a richer set of seamless information management solutions that encompass the aircraft and ground-based systems,β said Rockwell Collins CEO and president Kelly Ortberg.
