|Quoting Lrgt (Thread starter):|
With all the information on the internet, there seems there to be no website that lists aircraft's fuel burn numbers!
It's highly proprietary. As noted in prior replies, actual fuel burn is very sensitive to a whole bunch of factors (environmental, procedural, and technical). The Flight Management Computers on all current-generation airliners have very accurate models for fuel burn so this information is known, it's just not released because the people that have it have spent a lot of time and money developing it and they're not going to give it away for free.
