The Airbus A320 family was the first airliner to feature a full glass cockpit and digital fly-by-wire flight control system. The only analogue instruments were the radio magnetic indicator, brake pressure indicator, standby altimeter and artificial horizon, the latter two being replaced by a digital integrated standby instrument system in later production models.
Airbus aircraft designs after the A300/A310 are almost completely controlled by fly-by-wire equipment. These newer aircraft, including the A320, A330, A340, A350 and A380 operate under Airbus flight control laws. [7] The flight controls on the Airbus A330, for example, are all electronically controlled and hydraulically activated.
A fly-by-wire (FBW) system replaces manual flight control of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires (hence the term fly-by-wire), and flight control computers determine how to move the actuators at each control surface to provide the expected response ...
Bernard Ziegler was the most influential figure in developing the cockpit design and fly-by-wire control system for the Airbus airliners. He proposed that numerous technological innovations be applied to Airbus aircraft; for example, using composites, twin-engine configuration for the A300, fly-by-wire and many others.
The Airbus A320 was the first commercial aircraft to incorporate full flight-envelope protection into its flight-control software. This was instigated by former Airbus senior vice president for engineering Bernard Ziegler. In the Airbus, the flight envelope protection cannot be overridden completely, although the crew can fly beyond flight ...
The Airbus A320 is a low-wing airliner with twin turbofans and a conventional tail. The Airbus A320 family are narrow-body (single-aisle) aircraft with a retractable tricycle landing gear and powered by two wing pylon-mounted turbofan engines. After the oil price rises of the 1970s, Airbus needed to minimise the trip fuel costs of the A320.
The A320 was the first commercial jet to use a digital fly-by-wire control system. All Airbus aircraft developed since then have cockpit systems similar to the A320, making it easier to train crew. The success led Airbus to introduce a lengthened version, the A321 in 1993, along with the shorter A319 in 1995 and the even shorter A318 in 2002.
The Airbus A318 is the smallest and least numerous variant ... The A320 family pioneered the use in commercial aircraft of digital fly-by-wire flight control ...
