The AFCS PITCH and ROLL channels are redundantly powered from which DC buses?

Explanation:
The key idea is redundancy for critical flight-control electronics. The AFCS pitch and roll channels are fed from both main DC buses so that if one bus loses power, the other canKEEP the AFCS functioning. This dual-feed arrangement ensures continued control authority and stabilization even in the event of a bus fault or generator issue. The battery bus exists to power essential systems in an electrical emergency, but it is not the normal source for these AFCS channels. Relying on the battery bus would remove the intended redundancy and could compromise flight control if both main buses failed.
