What does it indicate if the DC VOLTS meter flickers while on battery power?

If the DC VOLTS meter flickers while on battery power, it may indicate that there is an unstable reading being provided by the system. In this scenario, an accurate voltage reading is critical for assessing the health of the battery and the overall power system. Flickering typically suggests fluctuations that could be interpreted as a lack of stable voltage, possibly due to poor connections or issues within the battery system itself.

Therefore, the indication is that there is a potential problem present, which warrants investigation. A flickering meter does not reflect the reliability or correctness of the voltage reading displayed; rather, it signals that something is amiss and inconsistent. Thus, the correct interpretation should align more closely with the need for further assessment rather than confirming that the displayed voltage is indeed correct. Recognizing and reacting to such discrepancies is essential for maintaining proper operational readiness and safety in aircraft systems.
