Why do some 747 have 5 engines?
Why do some 747 have 5 engines? Among commercial aeroplanes, this facility of carrying a spare engine, known as the fifth pod in aviation circles, is the most effective and fastest way of transporting a huge aircraft engine by air, though due to the extra weight of the engine the speed of the airliner gets reduced to some extent.
Why is 747 obsolete?
Built in 1967 to produce the mammoth jet, it remains the world's largest manufacturing plant according to Boeing. But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes.
Is the A380 retired?

How much fuel does a 747 burn during taxi?
But it's much more than a time waste. It's also a big source of carbon emissions. The average taxi time in the U.S. is between 16 and 27 minutes, which accounts for about 5% of a flight's fuel consumption. A Boeing 747, for example, uses 1 ton of fuel during a 15-minute taxi.
Why does 747 have a hump?

Why do airlines not like the A380?
The arrival of the A380 in 2007 was poorly timed. The price of jet fuel had begun to creep up, and by 2007 was floating at around $4 a gallon. This made airlines shy away from the expensive to operate four engine jets of the 80s and 90s, and to look instead to fuel efficiency as a major deciding factor.
Is the 747 better than the A380?
The B747's range falls slightly short of the A380, with a typical range of around 7,790 nautical miles (14,400 kilometers).

Can a 747 land without engines?
Without engine thrust, the 747 had a glide ratio of 15:1, meaning it can glide forward 15 kilometres for every kilometre it drops. After calculating the glide ratio, the crew realized that they had less than 30 minutes to regain power before they smashed into the ground.
