The new technologies in flight control avionics systems selected for the Boeing 777 airplane program consists of the following: Fly-By-Wire (FBW), ARINC 629 Bus, Deferred Maintenance. The FBW must meet extremely high levels of functional integrity and availability. The heart of the FBW concept is the use of triple redundancy for all hardware resources: computing system, airplane electrical power, hydraulic power and communication path. The architecture of the 777 flight controls system follows… Expand
