Engine Instrument Crew Alerting System (EICAS) & Standby Flight Display

Accessible through a single click of the EICAS button, or the CDU button. EICAS is by default always shown in the center of the CDU, except when navigating the STAT pages. The EICAS display is used to give the crew an overview of aircraft systems operation. Some of the key engine indications are also shown on the Standby Flight Display.
