Avionics And Systems

Avionics

Large-format displays: 5 large LCD screens (15.1 inches) replacing traditional instruments and gauges
Glass cockpit: all-digital flight deck with few mechanical instruments
Head-up display (HUD): optional, provides pilots with critical flight data on a transparent display
Engine indicating and crew alerting system (EICAS): monitors and displays engine and aircraft system information
Cursor control device (CCD): allows pilots to navigate and select options on the screens

Autopilot and Flight Control Systems

Autopilot: dual autopilot system with integrated flight control and autothrottle
Fly-by-wire (FBW) flight control system: replaces mechanical linkages with electronic signals
spoiler-based speed brake system: uses spoilers to assist in slowing down the aircraft

Communication systems: include VHF, HF, and SATCOM radios
Navigation systems: include GPS, INERTIAL, and DME navigation
** Automatic dependent surveillance-broadcast (ADS-B)**: broadcasts aircraft position to air traffic control and other nearby aircraft

Electrical and Hydraulic Systems

Electrical system: includes four 250 kVA generators, two starter generators, and two battery-powered electric systems
Hydraulic system: includes three hydraulic pumps, three reservoirs, and hydraulic fluid cooling system
