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.
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]
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.
Some alternatives are:
The system is called EICAS at least on the following aircraft:
The first Boeing airliner with EICAS was the Boeing 757. The Boeing 747 has EICAS since the 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.
The Saab 2000 has EICAS.
The Dornier 328 and the Dornier 228NG have EICAS.
The Xi'an MA60 and the Xi'an MA600 have EICAS.
On some Bombardier aircraft, it is possible to call up the wrong checklist. Messages forbidding take-off can be shown as advisories. [3]
The 757, 767, and 747-400 have no electronic checklists.
The ERJ and the E-Jets have no electronic checklists.
The CRJ have no electronic checklists.
The Do-328 and the Do-328JET have no electronic checklists.
The Saab 2000 has no electronic checklists.
The Boeing 767 is an American wide-body airliner developed and manufactured by Boeing Commercial Airplanes. The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982. The initial 767-200 variant entered service on September 8, 1982, with United Airlines, and the extended-range 767-200ER in 1984. It was stretched into the 767-300 in October 1986, followed by the extended-range 767-300ER in 1988, the most popular variant. The 767-300F, a production freighter version, debuted in October 1995. It was stretched again into the 767-400ER from September 2000.

The Embraer ERJ family are regional jets designed and produced by the Brazilian aerospace company Embraer. The family includes the ERJ 135, ERJ 140, and ERJ 145, as well as the Legacy 600 business jet and the R-99 family of military aircraft.
A glass cockpit is an aircraft cockpit that features an array of electronic (digital) flight instrument displays, typically large LCD screens, rather than traditional analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges to display information, a glass cockpit uses several multi-function displays and a primary flight display driven by flight management systems, that can be adjusted to show flight information as needed. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. In recent years the technology has also become widely available in small aircraft.
Boeing Commercial Airplanes (BCA) is a division of the Boeing Company. It designs, assembles, markets, and sells commercial aircraft, including the 737, 767, 777, and 787, along with freighter and business jet variants of most. The division employs nearly 35,000 people, many working at the company's division headquarters in Renton, Washington or at more than a dozen engineering, manufacturing, and assembly facilities, notably the Everett Factory and Renton Factory, and the South Carolina Factory.
The Embraer E-Jet family is a series of four-abreast, narrow-body, short- to medium-range, twin-engined jet airliners designed and produced by Brazilian aerospace manufacturer Embraer.
The Fairchild Dornier 728/928 family was a series of jet-powered regional airliners that was being developed by German-American aviation conglomerate Fairchild Dornier.
In aviation, an electronic flight instrument system (EFIS) is a flight instrument display system in an aircraft cockpit that displays flight data electronically rather than electromechanically. An EFIS normally consists of a primary flight display (PFD), multi-function display (MFD), and an engine indicating and crew alerting system (EICAS) display. Early EFIS models used cathode ray tube (CRT) displays, but liquid crystal displays (LCD) are now more common. The complex electromechanical attitude director indicator (ADI) and horizontal situation indicator (HSI) were the first candidates for replacement by EFIS. Now, however, few flight deck instruments cannot be replaced by an electronic display.
Shreveport Regional Airport is a public use airport in Shreveport, Louisiana, United States. It is owned by the City of Shreveport and located four nautical miles (7 km) southwest of its central business district.
A cargo aircraft is a fixed-wing aircraft that is designed or converted for the carriage of cargo rather than passengers. Such aircraft generally feature one or more large doors for loading cargo. Passenger amenities are removed or not installed, although there are usually basic comfort facilities for the crew such as a galley, lavatory, and bunks in larger planes. Freighters may be operated by civil passenger or cargo airlines, by private individuals, or by government agencies of individual countries such as the armed forces.
Glacier Park International Airport is in Flathead County, Montana, United States, six miles northeast of Kalispell. The airport is owned and operated by the Flathead Municipal Airport Authority, a public agency created by the county in 1974. The airport is near Glacier National Park.
A regional jet (RJ) is a jet-powered regional airliner with fewer than 100 seats. The first one was the Sud-Aviation Caravelle in 1959, followed by the widespread Yakovlev Yak-40, Fokker F-28, and BAe 146. The 1990s saw the emergence of the Canadair Regional Jet and its Embraer Regional Jet counterpart, then the larger Embraer E-Jet and multiple competing projects. In the US, they are limited in size by scope clauses.
A narrow-body aircraft or single-aisle aircraft is an airliner arranged along a single aisle, permitting up to 6-abreast seating in a cabin less than 4 metres (13 ft) in width. In contrast, a wide-body aircraft is a larger airliner usually configured with multiple aisles and a fuselage diameter of more than 5 metres (16 ft), allowing at least seven-abreast seating and often more travel classes.
An electronic centralised aircraft monitoring (ECAM) or electronic centralized aircraft monitoring is a system that monitors aircraft functions and relays them to the pilots. It also produces messages detailing failures and in certain cases, lists procedures to undertake to correct the problem.
The Fairchild Dornier 428JET was a program undertaken by American company Fairchild Dornier to develop a 44-seat regional jet aircraft. The program was part of a broader attempt by the company to develop a family of regional jets, comprising the 328JET, 428JET, and the 728 series. This family of aircraft was designed to compete with the Bombardier CRJ and Embraer ERJ/Embraer E-Jets families. The aircraft was announced on May 19, 1998. It was cancelled in August 2000.
