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.
This requirement led to the development and use of specialized software such as model-based systems engineering (MBSE) tools. The application development toolset SCADE (from Ansys ) (not to be confused with the application category SCADA ) is an example of an MBSE tool and has been used as part of the development of FADEC systems.
Two aircraft manufacturers produce commercial passenger aircraft with primary flight computers that can perform under different flight control modes. The most well-known is the system of normal, alternate, direct laws and mechanical alternate control laws of the Airbus A320-A380. [3]
The first derivative of the A320 was the Airbus A321, also known as the Stretched A320, A320-500 and A325. [9] [25] Its launch came on 24 November 1988 after commitments for 183 aircraft from 10 customers were secured. [9] [26] The aircraft was to be a minimally changed derivative, apart from minor wing modifications and the fuselage stretch ...
The Airbus A320neo family is an incremental development of the A320 family of narrow-body airliners produced by Airbus.The A320neo family (neo being Greek for "new", as well as an acronym for "new engine option") is based on the enhanced variant of the previous generation A319, A320, and A321, which was then retrospectively renamed the A320ceo family (ceo being an acronym for "current engine ...
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 ...
The A320 engine, the PW1100G, had made its first static engine test run on November 1, 2012, [20] and was first tested on the 747SP on May 15, 2013. [21] The first flight of the Airbus A320neo followed on September 25, 2014. [22] The PW1100G engine achieved FAA type certification on December 19, 2014. [23]
Brake to Vacate (BTV) is additional software planned by Airbus for incorporation on its line of airliners, intended to reduce runway overruns. A more tangible benefit is the increased ability to exit the runway at a specified turnoff point.
