What technique is key for effective fuel management?

Consistent monitoring of fuel levels and usage is essential for effective fuel management as it allows aircrew to track consumption patterns and make informed decisions throughout a flight. By keeping a close eye on fuel levels, aircrew can identify potential issues before they become critical, ensuring that they can make adjustments to flight plans or initiate fuel-saving measures when necessary. This active oversight helps to maximize the efficiency of fuel usage, ultimately leading to safer and more cost-effective operations.

Regular flight path evaluation, while important, does not specifically focus on the proactive management of fuel levels in real-time, leaving a gap in direct oversight of fuel consumption. Reducing overall passenger weight can contribute to fuel savings, but it is not always feasible or effective in managing fuel throughout the entirety of a flight. Increasing altitude may provide some fuel savings due to reduced drag, but this also depends on aircraft performance and operational requirements, making it a less reliable technique without the direct oversight provided by monitoring fuel usage.
