What is the correct calculation for trip fuel?

The correct calculation for trip fuel encompasses the fuel consumption from the moment the aircraft takes off until it lands at the destination. This measure is crucial for flight planning, as it provides an accurate estimate of the amount of fuel needed for the entire journey, excluding taxiing on the ground before takeoff and after landing.

Taking into account the dynamics of flight, the trip fuel calculation considers various phases of the flight, including climb, cruise, and descent. By focusing on the entire phase of flight from takeoff to landing, it allows operators to assess not only fuel efficiency but also operational safety and compliance with regulations regarding fuel reserves.

This choice differentiates itself by encompassing all necessary segments of the flight, providing a comprehensive view essential for ensuring sufficient fuel for the entire flight operation.
