12.5 A340 Particularities
System • Control laws
12.6 Design, Development, and Validation Procedures
Fly-by-Wire System Certification Background • The A320 Experience • The A340 Experience
12.7 Future Trends
12.1 Introduction
The first electrical flight control system for a civil aircraft was designed by Aerospatiale and installed on the Concorde. This is an analog, full-authority system for all control surfaces. The commanded control surface positions are directly proportional to the stick inputs. A mechanical back-up system is provided on the three axes. The first generation of electrical flight control systems with digital technology appeared on several civil aircraft at the start of the 1980s with the Airbus A310 program. These systems control the slats, flaps, and spoilers. These systems were designed with very stringent safety requirements (control surface runaway must be extremely improbable). As the loss of these functions results in a supportable increase in the crew’s workload, it is possible to lose the system in some circumstances.
