Which part of a flight consumes the most fuel?

BOSTON- It might be a while since many of us have flown commercially, but we don’t forget that feeling of being pushed back into our seat as the pilot put the plane on full throttle so as the plane began to accelerate along the runway. As the plane begins to rise, we can believe that the engines are working the hardest and consuming the most fuel. While take-off may be the most intense point of a flight in terms of fuel consumption, is it true – as some of us have been led to believe – that this consumes more fuel than any other part flight?

9 Feb. 2022 – OAG Labs used data from 10 flights from London Heathrow Airport to various destinations, including a short hop to Paris in an Airbus A319 and a long trip to Hong Kong in an A350. The other flights were to Athens (ATH), Dubai (DXB), Edinburgh (EDI), Geneva (GVA), Helsinki (HEL), Lisbon (LIS), Madrid (MAD) and New York (JFK).

“Total fuel burned is an important metric, but so is efficiency,” Rowland writes. “Aircraft capacity, age and engine type all contribute significantly to relative fuel burn. In our example, the A380 used to fly in Dubai uses nearly 14 liters of fuel per kilometer flown. while the newest A350 to Hong Kong uses only 6.0, less than the A319 to Paris.Meanwhile, the A321neo, one of the newest aircraft, consumes an average of 2.7 liters of fuel per kilometre.”

OAG’s experiment used nine Airbus planes and a Boeing 777 and measured fuel burn in six segments: departure, takeoff, climb, cruise, approach and landing.
