Prior to the 1970s, cockpits did not typically use any electronic instruments or displays (see Glass cockpit history).Improvements in computer technology, the need for enhancement of situational awareness in more complex environments, and the rapid growth of commercial air transportation, together with continued military competitiveness, led to increased levels of integration in the cockpit.
Avidyne was first to certify big glass for light GA with the 2003 launch of Entegra in Cirrus aircraft. This is considered a "first generation" big-glass system that integrates the six 3-inch instruments (6-pack) into a more usable package, along with an exceptionally reliable Air Data and Heading Reference System (ADAHRS) that replaces the "spinning mass" attitude and directional gyros.
SmartDeck is the only glass cockpit system in the light aircraft market that includes a display dedicated to such functions. Because radio frequencies, flight plan data and airport info can also be manipulated on the MFD, SmartDeck provides a “feature in use” annunciation if the user is accessing or modifying information in two places at once.
Earlier LCD panels suffered from poor legibility at some viewing angles and poor response times, making them unsuitable for aviation. Modern aircraft such as the Boeing 737 Next Generation, 777, 717, 747-400ER, 747-8F 767-400ER, 747-8, and 787, Airbus A320 family (later versions), A330 (later versions), A340-500/600, A340-300 (later versions ...
PFD with key instrument displays labelled PFD of a Garmin G1000. The details of the display layout on a primary flight display can vary enormously, depending on the aircraft, the aircraft's manufacturer, the specific model of PFD, certain settings chosen by the pilot, and various internal options that are selected by the aircraft's owner (i.e., an airline, in the case of a large airliner).
Enhanced vision systems use thermal and infrared cameras to see real-time images and help turn obscurants such as bad weather, night time, fog, dust and brownouts into better images that can see 8-10 times farther than the naked eye. There are some safety concerns with all glass cockpits, such as the failure of the primary flight displays (PFD).
