COMPETING BEAUTIES IN THE SKY (A380 VS B747-8)
The
world’s largest jetliner, Airbus A380, has dominated the skies since its
introduction in 2007. Now it has a contender. Boeing’s
recent innovation, the 747-8 Intercontinental, is in direct competition with
the massive A380. Both craft sit at the top of their class, feature similar
characteristics, and compete for a dominant share of the same passenger market.But
which is better? Both planes attracted quite a buzz when they were first
unveiled, but who reigns supreme? The following comparison reveals the hard
facts behind the “face-off of the year” in the aviation community.
Capacity
In
typical 3-class configuration the A380 can seat nearly 530 passengers. The
747-8 certainly scores slightly lower at only 467 passengers. However, the
numbers of passengers on a certain airplane can vary depending on seat
configuration requirements of a particular airline. Another
factor to consider: a few more seats aren’t always a draw to airlines looking
to purchase a new craft. “With an A380, you run the risk of not filling every
seat whenever you fly,” remarked Boeing deputy program manager Elizabeth Lund,
during the premiere of the 747-8 last month.Since
its introduction, however, the popularity of the jumbo Airbus among airlines
has remained strong. According to Airbus, as of Feb. 2011, the total orders
amount to 244, with 44 craft currently in operation.Since
it was only recently unveiled, orders for the new 747-8 are just beginning:
Korean Air, Cathay Pacific, and Lufthansa are the fist to place orders for the
plane.

In terms of overall length, the 747-8 bests
the A830. At over 250 feet, the 747-8 is currently the longest commercial
airplane in the skies—about 13 feet longer than the A380.
But
the A380 still remains the world’s tallest aircraft at almost 80 feet. The
747-8 is just shy of 64 feet.The
Airbus 380 may not be the longest, but it still carries more passengers. In the
end, it all comes down to choosing a model that fits the needs of a particular
airline. Customer orders will show if Boeing got it right again.
Price
Engine
choice, design weights, and level of selected customization by airlines are
some of the options that factor into the price of a plane. The
Boeing 747-8 is priced at just over $317 million, while the Airbus 380 costs
considerably more—$375 million. Airbus increased its catalog price nearly 8.4
percent at the beginning of the year.If
airlines are to choose between the A380 and the 747-8 due to cost alone, the
decision is simple—for every five Airbus craft purchased, a customer can buy
six of the Boeing.
Speed and Range
According
to Airbus tech specifications, the 380 can fly at a maximum cruising speed of
Mach 0.89. The 747-8, meanwhile, only offers a maximum speed of Mach
0.86. Of
course, as passengers, we feel little of the speed when flying.The
range of the A380 shows it can travel over 9500 miles in a single trip, while
the 747-8 will not fly much beyond 9200 miles.The
world definitely looks much smaller nowadays when taking a trip from New York
to Hong Kong, from LA to Mumbai, or from London to Singapore—trips that these
crafts are capable of.
Fuel Economy
With
rising fuel prices, and low-budget airlines on the rise to meet travelers’
demands, of significant concern is how much fuel a plane will burn to take a
large number of passengers from point A to point B.Both
planes are designed with innovative ideas to meet real economic concerns. These
formidable craft incorporate features such as new wing designs, improved
engines, and lighter materials to achieve the best possible fuel efficiency
based on number of seats and distance traveled.“The
747-8 has the lowest operating costs of any airplane in its class; the lowest
trip cost; the lowest cost per seat mile; and the lowest fuel burn per seat
mile,” explained Jim Proulx, Boeing Commercial Airplanes Communications.On
its website, Boeing offers a host of reasons why their craft trumps the Airbus.
Compared to the A380, the 747-8 claims to be 10 percent lighter per seat and it
burns 11 percent less fuel per passenger.So
what does Airbus say? Unfortunately, Airbus press offices both in Europe and
the U.S. could not be reached about the comparative fuel efficiency of the
competing craft.But
the showdown between the A380 and 747-8 is far form over. In a WSJ online
article from Feb. 13th, an Airbus executive claims that the 747-8 has yet to
pass evacuation tests.“Boeing
will meet or surpass every requirement for passenger evacuation,” countered
Boeing’s Proulx.According
to Proulx, “about one third of the market that Boeing sees for very large
airplanes (400 seats and up) over the next 20 years is for freighter
airplanes.”In
early 2007, Airbus made an announcement suspending the development of the A380
freight version, and as Boeing claims, “it was too heavy and inefficient,
meaning that the 747-8 is the only airplane in that market.”
