Question: 1 / 550

When are fuel quantity gauges usually considered accurate?

Always check them visually

Only when tanks are full

Only when tanks are empty

Fuel quantity gauges are typically considered accurate when calibrated regularly. Calibration ensures that the gauges provide precise readings, reflecting the actual fuel levels in the tanks. Regular calibration takes into account various factors that can affect gauge accuracy, such as temperature fluctuations, changes in fuel density, and the condition of the gauge itself.

Relying on visual checks or the state of the tanks—whether full or empty—does not account for the inherent limitations and potential inaccuracies of fuel gauges. It’s important to recognize that fuel gauges can be affected by various operating conditions, and they may not provide reliable information unless they have been verified through proper calibration procedures.
