Home' Asian Aviation : AAV February 2011 Contents At a time when Airbus has been
trumpeting the launch order for
its re-engined A320neo -- the
biggest single aircra order ever,
from India's IndiGo -- Boeing has
held o from such a radical move.
e US company has remained sceptical of the idea
of replacing the aircra 's CFM International CFM56
engines with new-generation powerplants such as the
CFM Leap-X or Pratt & Whitney's PurePower geared
turbofan, saying that the net economic bene t of such
a move would be just 3-4 percent, when everything is
taken into account.
Instead, Boeing is pinning its hopes on an all-new
single-aisle family that would o er more radical savings
but will not be available until beyond 2020. In the
meantime, the manufacturer argues, it can continue
to re ne its well-established 737 single-aisle family to
keep it competitive with any upgraded o ering from
European rival Airbus.
e Next-Generation 737 (737NG) -- a term that
applies to the -600, -700, -800 and -900 variants of
that aircra family -- went into service about 12 years
ago, and Boeing says that it has not stopped improving
the aircra since then. e incremental upgrades have
ranged from the addition of fuel-saving winglets to
lighter, carbon- bre brakes rst optioned in 2008.
roughout, the aircra family has consistently won
a steady ow of new orders thanks to its reputation for
reliability and solid performance.
"We have a 99.8 percent dispatch reliability," said
Beverly Wyse, vice-president and general manager
of the 737 programme. "While we are proud of the
progress we have made on this airplane, we are by no
Improved cabin, economy
Boeing's latest improvements to the aircra include:
a complete makeover for the aircra 's cabin, o ering
more room and passenger comfort; and airframe and
engine enhancements that cut fuel consumption and
carbon emissions by at least 2 percent.
" is is a perfectly e cient airplane," said John
Hamilton, chief project engineer on the aircraft
family. "We are at the point now where the industry
Boeing refines a classic
While Boeing has so far shied away from offering a re-engined version of its single-aisle 737 family, it is offering
substantial performance gains with aerodynamic and engine improvements, as well as an all-new cabin, writes

Boeing's moving 737 production line was based on lessons learned from automaker Toyota's lean manufacturing system.
