As a general reference, here are some approximate fuel consumption rates for different Boeing 747 models during the take-off phase:
- Boeing 747-400: Around 5,500 to 6,000 gallons of fuel (20,800 to 22,700 liters) per engine.
- Boeing 747-8i: Around 6,000 to 6,500 gallons of fuel (22,700 to 24,600 liters) per engine.
These fuel consumption rates are typically for a standard take-off procedure, which involves gradually increasing the thrust of the engines to accelerate the aircraft down the runway until it reaches its take-off speed. The actual fuel consumption may differ from these estimates depending on the specific circumstances of the take-off.
Please note that these fuel consumption rates are just approximate values and can vary significantly based on the factors mentioned earlier. Airlines have implemented various strategies, including optimizing flight plans, using advanced technology, and training pilots on efficient flying techniques, to minimize fuel consumption and improve operational efficiency.
