Many years ago I heard a very strange piece of news... According to this an airplane taxis more kilometers on airport aprons than it flies in the air - on an average...
If this is true then it is a tragedy of economy... A flight means 1,000 to 15,000 kilometers - and an airplane rolls more than this? This means that aircraft (up to USD 330 or 380 million) are hardly ever in the air...
However you can understand even this nightmare - because who has got on Earth 50 - 60 tons of jet fuel for one long-haul flight? If you quit buying the Boeing 747-8 Intercontinental then you can spare both the respectable price of the airliner and the oceans of jet fuel connected to this monster...
The real fuel consumption of a Jumbo Jet in the air can be reconned out from its power output... The power output is not the thrust but it can be reconned out from the weight of the airplane, its speed and the duration of the flight...
In other words a Boeing 747-8 Intercontinental may seem giant (and it is giant actually) but when it flies it must be lighter than air (this is a miracle of technology) - and a Jumbo Jet speeds faster than 900 km/h: it is faster than any hurricane... Of course, you also have to heat the airplane during the flight, you have to supply the air-conditioning and other electric systems with power and you have to supply the hydraulic systems with power, too - so appreciations to the busy little auxiliary power unit...
If anybody is considering to acquire a Boeing 747-8 Intercontinental after re-thinking its energy balance you can contact The Boeing Company: Boeing.com
