Which fuel type is used for a flight from takeoff to landing?

The term that best describes the fuel used for a flight from takeoff to landing is "trip fuel." This specifically refers to the amount of fuel required for the aircraft to complete its flight from the departure airport to the destination airport, accounting for the planned route and any necessary adjustments during the flight.

Trip fuel is determined based on factors such as the aircraft's weight, the distance to be traveled, expected weather conditions, and any potential delays during the flight. This ensures that the aircraft has enough fuel to reach its destination safely while meeting operational requirements.

In contrast, taxi fuel refers to the fuel consumed while the aircraft is on the ground and taxiing before takeoff. Contingency fuel is the extra fuel that is important for addressing unforeseen circumstances during the flight, like diversions or holding patterns. Block fuel comprises the total fuel on board at the start of the flight, including taxi fuel, trip fuel, contingency fuel, and any reserves required. Therefore, while trip fuel is specifically focused on the journey from takeoff to landing, block fuel encompasses a broader range of fuel types utilized from gate to gate.
