EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including [[Exhaust gas temperature gauge|exhaust gas temperature]], fuel flow and quantity, oil pressure etc. Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control surface systems. EICAS has high connectivity & provides data acquisition and routing.<ref>{{Cite web|title=EICAS displays|url=http://www.astronautics.com/index.php?q=content/engine-instrument-crew-alert-system-display|url-status=dead|archive-url=https://web.archive.org/web/20110707181316/http://www.astronautics.com/index.php?q=content/engine-instrument-crew-alert-system-display|archive-date=2011-07-07|access-date=2020-12-03|website=Astronautics|publisher=Astronautics Corporation of America}}</ref>

EICAS is a key function of a [[glass cockpit]] system, which replaces all analog gauges with software-driven electronic displays.  Most of the display area is used for navigation and orientation displays, but one display or a section of a display is set aside specifically for EICAS.
The crew-alerting system (CAS) is used in place of the [[annunciator panel]] on older systems.  Rather than signaling a system failure by turning on a light behind a translucent button, failures are shown as a list of messages in a small window near the other EICAS indications.
==Alternative systems==
Some alternatives are:
* [[Electronic Centralised Aircraft Monitor]] (ECAM) on [[Airbus]]
* ''Centralized Fault Detection System'' (CFDS) on [[McDonnell Douglas]]
* ''Flight Warning System'' (FWS) on [[Fokker]]
* ''Engine Warning Display'' (EWD) on [[ATR (aircraft manufacturer)|ATR]]
* Комплексная система электронной индикации и сигнализации (КСЭИС) on [[Antonov]].
== Presence ==
The system is called EICAS at least on the following aircraft:
=== Jetliners  ===
The first Boeing airliner with EICAS was the [[Boeing 757]]. The [[Boeing 747]] has EICAS since the [[Boeing 747-400|747-400]]. No version of the [[Boeing 737]] has EICAS. The [[Boeing 717]] has CFDS, as it was originally a [[McDonnell Douglas]] product.
The [[Embraer ERJ family]] and the [[Embraer E-Jet family]] have EICAS.
The [[Bombardier CRJ]] and the [[Bombardier CSeries]] have EICAS.
The [[Fairchild-Dornier 328JET]] has EICAS.
The [[COMAC ARJ21]] and the [[COMAC C919]] have EICAS.
=== Turboprop airliners ===
The [[Saab 2000]] has EICAS.
The [[Dornier 328]] and the [[Dornier 228|Dornier 228NG]] have EICAS.
The [[Xi'an MA60]] and the [[Xi'an MA600]] have EICAS.

An engine-indicating and crew-alerting system (EICAS)[1] is an integrated system used in modern aircraft to provide aircraft flight crew with instrumentation and crew annunciations for aircraft engines and other systems. On EICAS equipped aircraft the "recommended remedial action" is called a checklist.

Components

EICAS typically includes instrumentation of various engine parameters, including for example speed of rotation, temperature values including exhaust gas temperature, fuel flow and quantity, oil pressure etc. Other aircraft systems typically monitored by EICAS are for example hydraulic, pneumatic, electrical, deicing, environmental and control surface systems. EICAS has high connectivity & provides data acquisition and routing.[2]

Limitations

On some Bombardier aircraft, it is possible to call up the wrong checklist. Messages forbidding take-off can be shown as advisories.[3]
