Principles,dual-dual system for yaw damper, rudder trim and rudder travel functions.,FAC1 &2 can be engaged at the same time,only one is active at a time,FAC1 first,FAC2 standby and synchronized on FAC1 orders,an automatic changeover occurs on FAC2 in case of disengagement or Failure of FAC1,FMGC 1 &Capt PFD normally use data from FAC1,FMGC2 & F/O PFD normally use data from FAC2,Only one system

Annuciator,Autopilot,General,Flight,Management,System,FMGS,FMGS,AP,FD,A/THR,Operating Principles,dual-dual system for AP and A/THR functions,AP,only one can be engaged in cruise mode.,both can be engaged when ILS mode i,s selected.,AP1 has prtority, AP2 standby.,A/THR,both are always engaged at the same time but only one is active.,FD,active when the electrical network is energized.,FMGC1 drives FD symbols on CAPT PFD,FMGC2 drives FD symbols on F/O PFD,one FMGC fails, the other drives FD symbols on,both PFDs,FMGCs normally in,dual mode,on the,master/slave,concept,Both FMGCs perform the same functions at the same time and use the same crew inputs on MCDU1 or MCDU2,If dual mode fails both FMGCs independent mode( each FMGC controls MCDU of its own side),One FMGC fails, the other take control of MCDU1 and 2 independently.,All FM functions available through MCDU1 or 2.,The slave system synchronizes on the master system for the initialization of the fight planning or for the modification and sequencing or for the performance modes or for the guidance modes or for the radio navigation.,initialization 初始化、起始、恢复初值,modification 更改,sequencing 程序化、顺序,AP,modes :cruise mode/ TOGA
