2. Avio Avionics Suite
2.1 General
The Avio Avionics Suite is a highly integrated avionics system that serves as the
basic systems architecture and interfaces with almost every aircraft function. Avio is
divided further into five functional areas.
1. Aircraft Computer Systems
2. Pilot Displays
3. Pilot Controls/Interfaces
4. Primary Sensors
5. Aircraft Subsystems (Electrical Power Generation/Distribution)
While there are five functional areas, the two Primary Flight Displays (PFDs) and two
Aircraft Computer Systems (ACS’) are considered the pillars of the avionics system.
Through a series of 30 data busses that interconnect all components of the avionics,
many of the operations of the aircraft are routed through a combination of these four
components. Data busses are electrical paths used to transfer data and instructions
back and forth between two computers and can be thought of as the pipes through
which information flows. It is along these data busses that commands are sent to
the aircraft and systems status information is then returned to the pilot.
