A glass cockpit is a cockpit, as used in aircraft and spacecraft, 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 (nicknamed "steam 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 airlines 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.
As aircraft displays have modernized, the sensors that feed them have modernized as well. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS) and air data computers (ADCs), improving reliability and reducing cost and maintenance. GPS receivers are usually integrated into glass cockpits.thumb|[[Airbus A380 glass cockpit featuring "pull out keyboards and two wide computer screens on the sides for pilots"
Safety
As aircraft operation depends on glass cockpit systems, flight crews must be trained to deal with failures. The Airbus A320 family has seen fifty incidents where several flight displays were lost.
