9/13/2023 0 Comments Small airplane cockpit![]() Most cockpit instruments were still analog, but cathode ray tube (CRT) displays were to be used for the attitude indicator and horizontal situation indicator (HSI). The Boeing 2707 was one of the earliest commercial aircraft designed with a glass cockpit. The increasing complexity of transport aircraft, the advent of digital systems and the growing air traffic congestion around airports began to change that. Also, computer technology was not at a level where sufficiently light and powerful electronics were available. ![]() Prior to the 1970s, air transport operations were not considered sufficiently demanding to require advanced equipment like electronic flight displays. Glass cockpits originated in military aircraft in the late 1960s and early 1970s an early example is the Mark II avionics of the F-111D (first ordered in 1967, delivered from 1970–73), which featured a multi-function display. While glass cockpit-equipped aircraft throughout the late 20th century still retained analog altimeters, attitude, and airspeed indicators as standby instruments in case the EFIS displays failed, more modern aircraft have increasingly been using digital standby instruments as well, such as the integrated standby instrument system. Later glass cockpits, found in the Boeing 737NG, 747-400, 767-400, 777, Airbus A320, later Airbuses, Ilyushin Il-96 and Tupolev Tu-204 have completely replaced the mechanical gauges and warning lights in previous generations of aircraft. The Boeing 757 and 767-200/-300 introduced an electronic engine-indicating and crew-alerting system (EICAS) for monitoring engine performance while retaining mechanical gauges for airspeed, altitude and vertical speed. GPS receivers are usually integrated into glass cockpits.Įarly glass cockpits, found in the McDonnell Douglas MD-80, Boeing 737 Classic, ATR 42, ATR 72 and in the Airbus A300-600 and A310, used electronic flight instrument systems (EFIS) to display attitude and navigational information only, with traditional mechanical gauges retained for airspeed, altitude, vertical speed, and engine performance. Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS) and air data computers (ADCs), improving reliability and reducing cost and maintenance. ![]() In recent years the technology has also become widely available in small aircraft.Īs aircraft displays have modernized, the sensors that feed them have modernized as well. They are also popular with airline companies as they usually eliminate the need for a flight engineer, saving costs. This simplifies aircraft operation and navigation and allows pilots to focus only on the most pertinent information. While a traditional cockpit relies on numerous mechanical gauges (nicknamed "steam gauges") to display information, a glass cockpit uses several multi-function displays driven by flight management systems, that can be adjusted to display flight information as needed. The Airbus A380 glass cockpit featuring "pull out keyboards and two wide computer screens on the sides for pilots" Ī glass cockpit is an aircraft cockpit that features electronic (digital) flight instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges.
