How much fuel does a Boeing 727 fuel burn?

Answer 1

Fuel Capacity of B727-100 is 8,186 Gallons. A B727-200 is 9,806 Gallons.

With the 727-100, 12,000 lbs is burned in the first half hour of flight. In the next half hour 4,000lbs is used and thereafter for the entire second hour, another 7,000 lbs is used, i.e. 23,000 lbs in two hours, for the third hour a further 7,300 lbs is burned.

One US Gallon is equal to about 6.7lb so I leave you to figure the rest.

Early Boeing 727-200 aircraft still used the JT8D-7/9 engines with about the same consumption, but the Advanced version was certified to higher weights with more powerful JT8D-15/17 engines.

Later model 727-200 aircraft with the more gas guzzling -15 or -17 engines at a rough guess might burn 20-30% more than the figures mentioned above.

All airliners burn the most just after take off and in the climb.

Answer 2

This intercontinental long range plane burns 5 to 6 litres of fuel per second during take off until it reaches 3000 ft then 3 to 4 liters per second until it reaches cruising level at 35000 ft where it burns 1 to 2 liters of fuel per second. These values are approximate. In her fuel tanks she carries 80000 liters of fuel.
