Something is fishy though. According to http://www.howstuffworks.com/question192.htm, a 747 burns 36,000 gal over a 10 hr flight, or about a gallon a second.
A gallon of Jet A has ~121 MJ. 121 MJ delivered in 1 second is 121 MW. Therefore, averaged over a 10 hour flight, you need 120 MW, or 24 FF’s. The difference
might be explained as a peak vs. average output.
Sounds about right… I doubt they would operate at anything near full power while cruising. I’m surprised these back-of-the-envelope type calculations are in that close agreement.
