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 to 1973), 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 Traditional gyroscopic flight instruments have been replaced by electronic attitude and heading reference systems (AHRS) and air data computers (ADCs), improving reliability and reducing cost and maintenance.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.

The act of flying a 172 might get you there, which, when it comes to an airplane aimed at no-time to low-time pilots, isn’t a bad thing-not the sleepy part, but, rather, the easy-to-fly part.This article needs additional citations for verification. (Or it might have been “soporific” or even “soporiferous ” it’s been a few years.) The point was, such reports will make you sleepy. A former colleague once described flight reports on the 172 as somniferous. It’s a form of beauty that tends to go unnoticed, though. The very first Cessna Model 172, a fastback with a straight tail. Their average appearance is a kind of perfection. That doesn’t mean there’s anything wrong with them-quite the opposite.
They seem invisible because there’s absolutely nothing noticeable about them. That’s because the Skyhawk is so profoundly unremarkable that it seems to defy close inspection, like the perfectly average-looking person who tends not to get spotted in the crowd. What remains to be said, as it turns out, is just about everything. So, what’s left to say about the Cessna 172 Skyhawk, the most-produced aircraft in history, one that has, as a model, amassed untold millions of hours behind the hands and (sometimes) feet of hundreds of thousands of pilots skilled or not-so-skilled? What more can be said about a plane that’s so ubiquitous that it makes up a big part of the very fabric of light plane aviation?
