When should engine start limitations be adhered to in order to prevent battery damage?

• A. When oil temperature is high
• B. When caution indicators are lit
• C. During battery operation
• D. When exceeding oil pressures

Answer: (C)

The correct choice is focused on the timing for adhering to engine start limitations to protect the battery from potential damage during battery operation. This is critical because the electrical demands during engine start can draw significantly from the battery, and if the battery is already in a compromised state or if it is operating at high temperatures, it can be damaged more easily.

Adhering to engine start limitations during battery operation helps ensure that the battery is not subjected to excessive stress, which can lead to degradation, reduced lifespan, or failure. The battery is pivotal for starting the engine and powering systems until the generator can take over, so managing its use is essential for the overall reliability of the aircraft systems.

In contrast, high oil temperature and pressures are more concerned with engine health rather than immediate battery impact. Caution indicators typically alert to system malfunctions but do not specifically pertain to battery safety during engine starts, and therefore, do not directly relate to preventing battery damage in the context of starting operations.
