What is the standby battery capacity in amp-hours?

• A. 10.4 Ah
• B. 5.2 Ah
• C. 8.0 Ah
• D. 12 Ah

Answer: (A)

Standby battery capacity is the amount of energy available to power essential aircraft systems when the normal electrical sources fail. It’s expressed in amp-hours because that rating directly corresponds to how long the battery can provide a given load. The value 10.4 amp-hours matches the aircraft’s published requirement for the standby power to sustain critical avionics and instruments for the mandated emergency duration. That precise capacity ensures the necessary time is covered; smaller capacities wouldn’t meet the duration, while larger ones aren’t needed for the design target.
