Which FMGC provides signals to the autopilots?

• A. FMGC 1 only
• B. FMGC 1 and FMGC 2
• C. FMGC 2 only
• D. Neither

Answer: (B)

In this setup, two FMGCs handle flight management and guidance, feeding the Flight Guidance System that drives the autopilots. Each FMGC runs its own guidance calculations and can provide commands to the autopilot channels, so both FMGCs contribute signals to the autopilots. This redundancy means the autoplots can continue to fly the aircraft even if one FMGC fails, with the remaining FMGC providing the guidance data and cross-checking to maintain a safe flight path.
