An engine-indicating and crew-alerting system (EICAS)
{{cite book|author=Wells|first1=Alexander T.|url=https://books.google.com/books?id=ZaFHUfaw9L0C&pg=PA245|title=Commercial aviation safety|last2=Rodrigues|first2=Clarence C.|publisher=McGraw-Hill Professional|year=2004|isbn=978-0-07-141742-6|edition=4th|page=245}} 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.{{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}}
Limitations
On some Bombardier aircraft, it is possible to call up the wrong checklist. Messages forbidding take-off can be shown as advisories.{{cite web|url=https://www.ainonline.com/aviation-news/business-aviation/2023-03-28/multiple-eicas-alerts-preceded-fatal-challenger-flight|title=Multiple EICAS Alerts Preceded Fatal Challenger In-flight Upset - AIN|first1=Gordon|last1=Gilbert|website=Aviation International News}}
