Normal Battery _______ V and _______ A?

Normal Battery _______ V and _______ A?

• A. 24 VDC, 17 Ampere-Hours
• B. 24 VDC, 43 Ampere-Hours
• C. 28 VDC, 17 Ampere-Hours
• D. 12 VDC, 17 Ampere-Hours

Answer: (A)

The electrical system on this aircraft is built around a 24-volt DC battery, and the battery’s capacity is described in ampere-hours to indicate how much energy it can store for a given current draw. For normal operations, the battery is 24 V DC with about 17 Ah of capacity. That combination provides enough power to start the engines and to supply essential systems when generators aren’t online, without needing a larger or higher-voltage battery. Other options either propose a higher system voltage (28 V) that isn’t standard for this airframe, a much smaller voltage (12 V) that wouldn’t meet the aircraft’s electrical needs, or a significantly larger capacity (43 Ah) than what is typically specified for normal operations. Hence, 24 V DC and 17 Ah is the best match.
