The Engine Indication and Crew Alerting System (EICAS) is designed by Boeing to provide all engine instrumentation and crew annunciations in an integrated format. The equivalent system on Airbus aircraft is the Electronic Centralized Aircraft Monitoring (ECAM) system.
The information supplied by EICAS/ECAM includes the display of engine torque, inter-stage turbine temperature, high and low-pressure gas generator (compressor) RPM, fuel flow, oil temperature, and pressure.
EICAS improves reliability through the elimination of traditional engine gauges and simplifies the flight deck through fewer standalone indicators. EICAS also reduces crew workload by employing a graphical presentation that can be rapidly assimilated. EICAS can also help to reduce operating costs by providing maintenance data.
EICAS is a key function of a glass cockpit system, which replaces all analog gauges with software-driven electronic displays.
EICAS simplifies flight deck clutter by integrating the many electro-mechanical instruments that previously monitored engine and aircraft systems. Safety is increased whilst the pilot workload is simplified. EICAS continuously monitors the aircraft for out-of-tolerance or abnormal conditions and notifies the crew when an event occurs.
