How much fuel is used for jet airplanes to take off?

The amount of fuel used by a jet airplane during takeoff depends on several factors, including the type of aircraft, its weight, the airport elevation, and the weather conditions. Here are some general estimates:

1. Short-haul flights: For short-haul flights (less than 500 miles or 800 kilometers), jet airplanes typically use around 2,000 to 4,000 pounds (900 to 1,800 kilograms) of fuel during takeoff.

2. Medium-haul flights: Medium-haul flights (500 to 1,500 miles or 800 to 2,400 kilometers) may require 4,000 to 6,000 pounds (1,800 to 2,700 kilograms) of fuel for takeoff.

3. Long-haul flights: Long-haul flights (over 1,500 miles or 2,400 kilometers) can consume significantly more fuel during takeoff. Some large passenger jets may use 8,000 to 12,000 pounds (3,600 to 5,400 kilograms) or even more fuel just to get off the ground.

These figures are rough estimates and can vary considerably depending on the specific aircraft, its engines, and the prevailing conditions. Fuel consumption during takeoff also contributes to an airplane's total fuel usage for the entire flight, which includes taxiing, climb, cruise, descent, and landing.
