Airbus Fly-By-Wire: A Total Approach To Dependability

This paper deals with the digital electrical flight control system of the Airbus airplanes. This system is built to very stringent dependability requirements both in terms of safety (the systems must not output erroneous signals) and availability. System safety and availability principles are presented with an emphasis on their evolution and on future challenges

A Process Toward Total Dependability - Airbus Fly-by-Wire Paradigm

The presentation deals with digital electrical flight control system of the Airbus airplanes. This system is built to very stringent dependability requirements both in term of safety (the system must not output erroneous signals) and availability. System safety and availability principles along with assessment process are presented with an emphasis on their evolution and on future challenges.

Energy Monitoring Assistance System For Large Civil Aircraft In The Approach Phase

Through a multidisciplinary approach based on flight mechanics and human factors, this study aims at finding new ways of safety enhancements during the approach and landing of a large civil aircraft. This article presents the overall process of a go around decision-making assistance design for the flight crew. This study resulted in the definition of a new kind of cockpit information, the Energy Stabilization Height, matching human factor constraints. The analysis of the physical problem ends up in an analytical approximation coupled with the resolution of an optimal problem. Numerical simulations were compared to simplified solutions and statistical results. The outcome of this concept could be a satisfying go around assistance tool.
