Which method helps pilots track fuel efficiency during flight?

Real-time monitoring and calculations provide pilots with the most accurate and up-to-date information regarding fuel efficiency during flight. This method allows pilots to analyze fuel consumption in conjunction with flight parameters such as speed, altitude, and weight. By using onboard systems, including fuel flow meters and performance management systems, pilots can calculate fuel burn rates, compare them against flight plans, and make informed decisions to optimize fuel use.

This active approach ensures that any discrepancies or changes in flight conditions are addressed promptly, allowing for better fuel management and planning for any necessary adjustments in the flight profile. It emphasizes data-driven decision-making rather than relying on subjective methods or outdated information, which would be less reliable when assessing fuel efficiency in dynamic flight environments.
