What is the difference between EFIS and EICAS?
EFIS displays flight instruments electronically instead of mechanically and includes a Primary Flight Display and Navigation Display. EICAS displays engine parameters and alerts crews to faults. It is similar to Airbus’ Electronic Centralized Aircraft Monitor (ECAM) system. The Electronic Centralized Aircraft Monitor (ECAM) is the Airbus version of an enhanced Engine Indicating and Crew Alerting System (EICAS) system. It presents data on the Engine/Warning Display (E/WD) and the System Display (SD) inclusive of: Primary engine indications, fuel quantity, flap and slat position.
