Cessna has chosen the new Honeywell Primus Epic integrated avionics system, including an engine indicating and crew alerting system (EICAS), for the Citation Sovereign. Cessna says that the system offers low acquisition, installation and life-cycle costs and high reliability. The Sovereign will feature four 8-inch by 10-inch active matrix quartz flat screen displays, including two Primary Flight Displays (PFDs), a Multi-Function Display (MFD) and an EICAS display.
