One advantage of electrical and electronic fuel quantity indicating systems is that?

The advantage of electrical and electronic fuel quantity indicating systems being able to show several fuel tank levels on one indicator is significant in modern aviation. This capability simplifies cockpit displays and reduces the space needed for multiple gauges, thus enhancing the overall efficiency of the instrumentation layout. In contrast to mechanical systems, which typically require separate indicators for each tank, electrical systems use electronic signals to relay data from multiple tanks to a single display. This not only improves readability for the pilot but also provides a more integrated view of fuel management, critical for safe flight operations.

While ease of maintenance and calibration are valid concerns, they might not always favor the electrical systems over mechanical ones. Similarly, while electrical systems may have some level of immunity to interference, they are not entirely immune, as certain conditions can still affect their performance. Hence, the ability to read multiple tank levels from one indicator is a distinct and practical benefit that highlights the advancements of electronic systems in aviation.
