What information does a digital fuel totalizer provide?

A digital fuel totalizer plays a crucial role in monitoring an aircraft's fuel management. It provides vital information that helps pilots make informed decisions regarding fuel usage and efficiency during flight.

The correct response includes several key data points: the amount of fuel used, the amount of fuel remaining, the current rate of fuel consumption, and the fuel weight. Tracking fuel used and remaining allows pilots to assess how much fuel has been burned during the flight versus how much is left. This information is essential for flight planning and managing fuel reserves to ensure safe operations.

The current rate of consumption is particularly important for optimizing fuel efficiency, allowing pilots to adjust power settings and throttle based on real-time data. Furthermore, knowing the fuel weight is crucial because it affects the aircraft's overall performance, including its weight and balance calculations. This comprehensive set of data allows for better operational decisions and enhances safety during flight.

In contrast, options that suggest limited data such as only total fuel aboard or only the current rate of consumption do not convey the full extent of information that a digital fuel totalizer provides. This capability to integrate multiple aspects of fuel management and present them clearly is what makes the comprehensive set of data essential for pilots.
