The PRIMUS
â
1000 Integrated Avionics System is a fail--passive
autopilot/flight director and display system that has a full complement
of horizontal and vertical flight guidance modes. These include all radio
guidance modes, optional long range navigation system tracking, and
air data vertical modes. Either the pilot’s or copilot’s electronic flight
instrument system (EFIS) can be coupled to the FGS for control of the
aircraft.
The IAC flight guidance function digitally processes heading,
navigation, and air data information to satisfy pilot requirements. The
data is presented to each pilot on EFIS displays.
The EDS displays attitude, heading, air data, navigation, and engine
instrument and crew alerting (EICAS) information.
