Fly-by-wire

GROUNDBREAKING INNOVATION

A key element of Airbus’ continued innovation is the application of digital fly-by-wire technology – which brings improved handling, enhanced safety and operational commonality to its product line of modern jetliners.

Introduced into civil aviation with Airbus’ single-aisle A320, fly-by-wire technology has allowed the company to develop a true family of aircraft through the highest degree of operational commonality, featuring nearly identical cockpit designs and handling characteristics.

SAFETY AND PERFORMANCE

Overall safety is increased with the use of fly-by-wire, which provides direct input through electrical signals for more precise commands. In addition, the control system monitors pilot commands to ensure the aircraft is kept within a safety margin called the “flight protection envelope.” As a result, pilots always can get the maximum performance out of Airbus aircraft without running the risk of exceeding these limits.

The use of fly-by-wire technology provides a number of operational advantages for Airbus aircraft, including higher precision during flight and lower maintenance costs.

OPERATIONAL BENEFITS

Operators benefit greatly from this key innovation, which allows for simplified crew training and conversion. In addition, pilots are able to stay current on more than one aircraft type simultaneously without supplementary takeoff/landing requirements, recurrent training and annual checks.

The weight savings from the replacement of heavy mechanical control cables provides a significant reduction in fuel consumption. As electrical controls are less complex and easier to maintain than mechanical ones, the use of fly-by-wire also translates to lower maintenance costs for operators.
