Which components provide redundancy to ensure avionics continue operation during faults?

• A. Ground power only.
• B. A single battery.
• C. Redundant power sources and inverters.
• D. Solar cells.

Answer: (C)

Having multiple independent paths to power avionics is essential so systems stay alive if one path fails. The best choice is redundant power sources and inverters because this setup provides multiple, independent supply routes: if one source or one inverter fails, others take over and continue feeding the avionics without interruption. Ground power alone won’t cover flight operations away from the ground or a ground support failure; a single battery offers no backup if that battery itself fails; solar cells by themselves aren’t a reliable, all-condition source for continuous avionics power. With multiple sources and inverters, the system can automatically transfer to a surviving path, maintaining operation during faults.
