The Joyce B/S barometer, page-44

The only arrogant and ignorant individual is you. Fuel consumption graphs are grossly simplistic and don't accurately reflect real world use.

Airlines use complex computer models to plan routes using dozen s of variables. These are adjusted on a per-flight basis

Here is real data from Singapore Airlines for the13,600Km San Francisco-Singapore route.

Flight Non-stop One-stop

Route SIN - SFO SIN-NRT NRT-SFO

Aircraft Airbus A350-900 Boeing 777-300ER Boeing 777-300ER

Consumption 99641 kg 69391 kg 102558 kg Consumption per Passenger 393 kg 249 kg 368 kg Consumption per Passenger and 100km 2.9 kg 4.5 kg 5.61 kg

The above demonstrated information refers to real operated flights between this cities. The results state clearly, that a flight on an Airbus A350-900 is more fuel efficient than a flight with a stop in Tokyo. For one passenger on the non-stop flight, 393 kg of fuel are required. For the same route but with a stop in Tokyo 617 kg are needed per passenger. Hence, 36% of fuel per passenger can be saved by using the A350-900 and flying non-stop.
